Aquarium Co-Op great video cory just got my new betta for my 180 litre tank😄

[@Ants_major]

Aquarium Co-Op do you have any tips to look after betta

[@arnodrijfhout3858]

Jack Kent Are you like a new guy to betta?

[@courtneycoulson1564]

Aquarium Co-Op hi Cory how comes out of all the live bearers you don't seem to like swordtails? ???

[@NeonTetraAquarist]

Aquarium Co-Op No Cory this is fine JUST THE WAY IT IS!😁😂😂😂😂😂

[@boscohemi3874]

One thing you can tell about this guy Cory is he is not out to rip anyone off. Explains everything right down to the penny. I wish We had a guy like this here! I would never buy from anyone else again.Guys like this everyone should support. ( Canada)

[@AquariumCoop]

Thank you for the kind words Bosco

[@wendysterlingcarr]

Bosco Hemi I always buy my sponge filters from Cory

[@aspectinc]

Bosco Hemi why did you put (Canada) in brackets ?

[@seratonin7004]

I agree! I'm in Australia

[@fishenthusiast5408]

@@AquariumCoop Could you please put a online shop in Canada if not I understand have a good day

[@djndjn]

Hey Cory. When your store recommended running my 55 with two sponge filters i was skeptical. They heard that my goal was to create a planted community tank. After five months, the water chemistry is so good that I have a hard time justifying water changes. My fish could not be happier as evident by the amount of offspring now swimming all over the tank. My plants grow like weeds and look amazing. I appreciate the great advice that I get from you and from your store team. Thank you!!

[@AquariumCoop]

+djndjn glad to hear it. Sounds like you have built a strong ecosystem.

[@CatFish107]

Replying years later to see if this sends you a notification, and to ask for an update on your tank, please. Hoping your ecosystem remains stable and vibrant.

[@ethanna1684]

I wish when i was sucking on my syphon changing water m&ms came out rather then gross aquarium water

[@AquariumCoop]

I wish they did too. Have you seen my video on how to gravel vac? In most cases you should be able to avoid ever having to suck on the end of the hose to start the siphon. kzbin.info/www/bejne/gorZZqFmlp1ohbs

[@ethanna1684]

Wow thats so much easier, thanks for linking that video

[@tbas8741]

You know that water specially Dirty is hundred times worse than LITERALLY Licking a Public Toilet Seat.. Another tip to start is end of hose in buck put a turkey baster or large syringe on it then pull the plunger up fast and all the way apart it will suck up and flow :D

[@bebebutterfield1]

My turtle tank makes chocolate walnut turtle candy....I wish.

[@ashleymaree329]

My husband did this the first time he tried vacuuming the gravel when I wasnt home... 😂😂 Laughed my ass off when I showed him how you can make it start siphoning without putting your mouth on it! 🤮

[@AdamTillontheWeb]

I wasn't sure I completely understood, so I went out and got my own educational props. I'm good now (and full).

[@AquariumCoop]

practice makes perfect.

[@OnHisDime]

haha

[@wendysterlingcarr]

Adam Till from Arctic Lights Aquatics yes I learned that I need m&m’s to cycle my tank. I love the process lol

[@twodaend]

Holy cow, this was one of the easiest to understand explanation of the nitrogen cycle and how bacteria colonizes I have ever seen. Now I think I understand why my fishless cycle is taking forever. Along with the tank and decor, I have a canister filter and obviously my tank and decor bowl has not fill up yet and/or I have so much more room still in my canister filter bowl, thus the bacteria is taking longer to fully colonize and eat the added ammonia. I'm going to keep waiting, but now I think I understand. Thx for a great video and explanation.

[@cremnallac4494]

twodaend do you have fish in your aquarium now?

[@peteon4wheels627]

This is the best way I have found on the net, Cory you need to take up teaching part time as your great at what you do, rock on Cory.

[@AQUAPROS]

Great video Cory, Love the way you chose to explain it :)

[@ADUAquascaping]

AQUAPROS 😎

[@jimmyreese4740]

This is the first Aquarium Co-Op video I ever watched and Cory did an amazing job explaining the nitrogen cycle.I was just about to give up so glad I found this video and became a better aquarium keeper an a Aquarium Co-Op fan for life.

[@lizhelm9922]

Thank you!!! Homeschooling family here. (I also love learning and enjoying nature!) I can not thank you enough for spreading your knowledge and passion. Your videos are personal and you're the teacher that says "there are no stupid questions" I can't thank you enough. I would have given up by now without your videos

[@CYL347]

I love how he explained the difference between nitrite and nitrate while pronouncing same.

[@rebeccasanders7890]

I think he is just recapping it for himself.

[@pawelmatus]

But my fish don't go to the bathroom, they just do it in the tank. lol

[@marshmellow6152]

Omg gold 😂😂

[@shane1489]

Bah Dum Tss 🥁

[@arnam3282]

I don't know how many times I watched this video, and I am still watching it. For me, this is the single most influencing video to get me in the hobby. For this, I am forever grateful 🙏🙏

[@jci8972]

Spot on with your analogies and making the topic really easy to digest 😆. This made the cycle process less daunting to deal with and answered so many questions I had. Thank you for putting time into your videos! We’ll be swinging by your shop again soon to say “hi” to Murphy!

[@piipaatirullaa]

Finally an aquarium video, which explains 'everything' crystallized in a few sentences. Thank you !

[@tinynina76]

You're a great teacher! Thank you. 😁

[@bookmouse770]

I was telling my family about your superior video and my daughter wants me to explain it to her while using M & Ms over the weekend. :-))

[@xfahrenheit2581]

The only video that made me understand that frickin' Nitrogen Cycle, made me subscribe on the spot! So nice of you considering us, visual learners! You're the best, man! Thanks!

[@myagroenhagen3991]

This is a brilliant way of teaching the Nitrogen Cycle! Thank you!!!!

[@AquariumCoop]

+Mya Groenhagen hope it helps someone out there :)

[@justjoshin5140]

You’re the best dude! You’re my go to for anything fish/aquarium I need to know. I appreciate the effort you put in so much. I’m basically going from only knowing fish need water to knowing everything like nitrogen cycle and a lot more so I can keep my fish and aquarium healthy and thriving!

[@2DebbieDoo]

WOW! Five years ago, I spent over a year researching and fretting before I finally put my tank up and "cycled" it. Then waited another 6 months before I finally put fish in, I fed the water food every day! I was a wreck over the nitrogen cycle. I learned MORE in 17 minutes then I ever learned from the web! AND it was a whole lot more fun, please tell your wife thank you!!! Take good care of you and yours.

[@plushpossum]

This is hands down the greatest video ever made for fish keepers. Anyone buying their first aquarium should be REQUIRED to watch this video!!! ❤Absolutely a staple in the hobby.

[@alimorland7524]

"Ite is yikes! and Ate is A-Okay!" was how I first taught myself the difference.

[@glendasworld4125]

Good one. I just learned the difference with no trick. Lol.

[@deborahjeanne2141]

😍 what a great way to remember!

[@elchicanofinikero1780]

This video actually helped me understand that a lot better, I'm planning to work at a fish store and now I know how to explain the nitrogen cycle to customers

[@ashpaws6708]

I love the way you filmed this with the cards and stuff. I had no idea about the Nitrogen Cycle until I started watching videos like this and looking on forums. It was soo confusing but this really cleared it up! Many of my fish in the past have died mysteriously, and now I understand why they did. There was probably sooo much ammonia in the tank! I feel really bad now, but luckily I am planning to get a tank with a couple mollies, so I can retry.

[@krissanamay2194]

I've been looking on KZbin for someone to explain this cycle to me so I can completely understand it, and you Sir, did that. THANK YOU!!!

[@justanotherpersonhi7215]

Every other video I found was vague or just trying to promote a "instant cycle" product, this is helpful to understand the processes

[@jimbobjones5014]

I'm about half way through the video, just finished the summary of the nitrogen cycle and wow it was made simple and understood, thank you so much for all your help and support with new aquarists 🙏👍😀

[@therandomgoat2908]

3 years late to comment but this really helpme understand more! I like how you make it more simpler than other youtubers. Thanks for the info!

[@dloz85]

Thanks for this video. I knew this but didn't KNOW it, you know?

[@PolarAzulTigris]

I just wanted to say thank you; this is my to go to video to explain the Nitrogen cycle to a new fish owner. Also first video I actually understood what I was doing wrong with mine so thank you again.

[@resilientrecoveryministries]

I am always impressed at how well Cory explains things.

[@mikehunt9392]

Corey, if I’m using an all in one fertilizer but then also using a water conditioner such as Fritz, which also removes ammonia nitrite and nitrates am I pretty much just wasting my money?

[@gavinjones916]

Omg thanks so much that made so much sense

[@tallen6285]

Love your videos. You have filled a niche that helps so many aquarium hobbyists with your knowledge and practical tips. Looking forward to more species videos, either fish or plants. Keep up the great work !!!!

[@dangavioli1656]

This is the single most important video for the new aquarist!!! Thank you Cory and all of the aquarium coop team that made this possible.

[@3D1ofakind]

You have no idea how helpful this video was, thank you. Subscribed

[@klutziekat7709]

This video is so wholesome! Love coming back and watching these old videos, the channel has grown so much 💙

[@laattardo]

I'm a beginner, and this video is great. I can say I had no idea about this subject and now I do! Thanks for putting this out there!

[@lilbmxman66akax999thhokage]

Dude, wow, holy crap this made this sooo much easier to understand 😅

[@wolfenspeign]

Thank-you so much! As a Fish Noob, who recently got a 5 gallon tank with some Guppies .. and being frequently unsure if things are good/not good, and using the wal-mart test strips to check if things are ok -- this video (and i've watched 5+ other ones on the nitrogen cycle now) really helped me truly understand what exactly is happening, and i can relax, as I also see my fish are just fine, and i've just been a bit paranoid. Thank-you so much for the excellent, very EASY visual explanation.

[@monique6ful]

I’m a newbie in the tank world and this was very clear and concise and made me understand. Thanks man I truly appreciate it

[@brooksmenard2256]

I wish my teachers at school taught like this I learned so much

[@brittanydrake5794]

Cory, this is amazing. Thank you soooooo much. This has answered so many questions as someone who is still fairly new to the hobby. This is a life saver 🙌🙏❤

[@ImJustFunSize]

Wow! This was the best teaching video ever. Thank you for making this so easy to follow!! 😊

[@kathieperron5627]

Thanks for your easy to understand videos with great explanations that get right down to the nitty gritty.

[@Thatblue35]

I’m just starting out with my first tank and your videos are helping me out so much! Thank you for making these videos which are easy to understand and are very helpful!

[@cristopherrodriguezmatias9337]

My godson understood the nitrogen cycle thanks to this video. I'm helping him start a new aquarium from scratch. Thanks for the amazing work.

[@martyndurrant1643]

that was awesome I was a bit confuced on what happens but now I'm all good so thank you for putting time and effort in doing this and I hope you enjoyed your m&ms

[@ZugieXIII]

This is by far the best Nitrogen Cycle video I have seen. Fantastic!

[@nathanhoveyaquatics]

Are watching in 2025. I don't think videos like this ever lose value. Thanks for making all the videos you have as they can be used as cheat sheets/ brain reminders.

[@kaglione]

Thank you, very easy to understand. Probably the best starter video I have seen.

[@TheFreakinpenguins]

Really great video! I did not think of the nitrogen cycle this way, but your demonstration made it easy to understand.

[@aljanecko]

Best video I’ve seen about the cycle, you made it very simple to understand.

[@skg122596]

I only recently got a water feature in my backyard and added 3 goldfish to it and am admittedly absolutely clueless as to how to maintain the best environment for them. This actually explained it to me in a way I could understand so THANK YOU!! I will definitely subscribe!!

[@AquariumCoop]

Glad the magic of candy could help ;)

[@karthikkannan6753]

Brilliant stuff candy man, Thks! 🇮🇳

[@LindaLights]

Such an excellent tutorial, especially for a beginner like me. Really get a lot out of your videos, thank you!

[@aliciap9922]

This is such a wonderful and simple way to explain the nitrogen cycle! I'm totally going to use this visual to help explain it in my pecha kucha in my public speaking class.

[@kaylawolfie1111]

I need a refresher since I just set up my new 40. Been a while since I last cycled a tank. So thank you man.

[@DiscuskwekerijBeSunshineValley]

30 years aquaristics and after seeing this video i can only say: YOU ROCK

[@tracytamura7121]

This is great . I will use this in homeschooling the kids today . Thanks

[@AquariumCoop]

Don't forget to pick up the m&ms! :P

[@tracytamura7121]

We have lots of m&ms from Easter . Lol. I have been trying to teach my 6 children about how to maintain a tank . They help with all aspects of a 120 Mbuna tank & a 75 planted angel & rainbow fish tank . This video will be an awesome teaching tool !

[@jem-agemstoneonlydiscovere8134]

Smashing video Cory. Helps visual learners like me. Learning is always fun. Just got into aquascaping and most of your videos re-assures me. Thanks and keep up the good deed!

[@Myname2663-w2z]

Best video ever! I loved the props. It really simplified the concepts and looked delicious. Thanks so very much.

[@Lifewithpets72]

This was fantastic information so clearly and concisely put! Those M&M though were making me hungry!

[@Carloszengotita]

really found this video very fun to watch it felt like I was back in school ,u did a terrific job Cory

[@monicabassett783]

Trying to get my 7yr excited about the hobby. He was totally into the M&M explanation. Thanks!

[@stojohnny]

Great video. I'll be sharing this with my brother and sister. I gave each of them aquariums a while back and this will far more informative than I was trying to explain it to them. Keep up the great work!

[@AtomicJenga]

Best video demo of "cycling" on the internet!!

[@fishtales2597]

Hi thank you for explaining this, I now understand how the tank cycle works. Brilliant.

[@peachypanda96]

Thank you for making this video Corey!! I'm in the process of researching and setting up my first proper aquarium and this was really helpful in understanding quite how the nitrogen cycle works! It can be a little confusing to new fish keepers and having a visual (and probably very tasty) representation of this process makes it so easy to figure out!! Of all the things I've learnt from your channel so far I think this one will stick with me the most!! As always, I love your videos - I find them not only really helpful in planning and understanding what i will need for my tank but also really fun to watch! I'm always looking for aquarium related channels but yours is always by far my favourite! My boyfriend and I are planning a trip to the US (we live in the UK) and I'm really hoping we can come and see the shop for ourselves!! I'd love to meet you someday as i feel like I could have a really interesting conversation with you and pick up loads of great tips!! Again, thank you for taking the time to make this content as I'm sure its exhausting running the channel, running your store and keeping up with all the comments people like me leave on your videos! I think I can speak on behalf of many of your subscribers when i say, seeing the little notification that tells me you have uploaded a new video really brightens my day!

[@AquariumCoop]

+peachypanda96 I'm glad I can help those new to the hobby. This video was targeted directly towards someone like you.

[@michellelemoignan608]

Really great video!! I love the work you put into actually showing the process through the use of M&Ms! Thank you for sharing!

[@aaronr5287]

Thank you so much for your videos man, I've been keeping fish now for about 3 months and I've learned so much from you brother. Thank you!

[@Mihigo26]

This video finally helped me understand it. Under-rated video, a must for any newbie! KUTGW.

[@johnwright3306]

I've learned so much from you , really makes the hobby easier and enjoyable

[@FlynnsFishForum]

Awesome video Cory! I really enjoyed it! The candy really made a good visual.

[@alanp1385]

You make it simple, you keep it light and you also entertain. You’re a funny guy Cory. That’s why I love your videos. Thx 👍

[@kyletullyowns]

Ive seen SO many of your videos but this is hands down the most entertaining 🤣 if only my water changes had blue m&ms come out of the hose.

[@Laura-wg1yp]

"I'm going to do some more water change" Sure Cory... sure 😜🙈😂

[@AquariumCoop]

You don't want to see my automatic water m&m changer :P

[@Laura-wg1yp]

[@CBales2006]

Best visual ever! I so needed this

[@marcoa.camacho1288]

Wow, came across this video and it is very very clear to me now what nitrogen cycle is. Thank you so much

[@amandamccollister7373]

you are so good at teaching people how to take care of their fish and aquariums. Thank you and God bless you.

[@Snowflake3981]

Cory - would love if you reshot this and made it into a 5-7 minute video. I recently got my nephews into fishkeeping and am trying to teach them some of the basics, a video would really help but I don’t think they’re patient enough for a 17 minute video. Better yet - do a whole series of videos for kids!

[@KalindiYoga]

Great video 👍 Using the M&M makes it much easier to understand. Thank you.

[@Michael10755]

Dude! your the absolute best! Extremely helpful, knowledgeable, and ya get me to chuckle at the same time.. Thanks @Aquarium Co-Op

[@AquariumCoop]

Thanks for the kind words.

[@Michael10755]

Aquarium Co-Op You're welcome.

[@Daveydriver]

Excellent video Cory. I would love it if you could do a video on maintaining healthy bacteria when you do a major overhaul on your tank. Especially when your filters are switched off for some time.

[@joannemcneill156]

This was really fun to watch. I've never seen nitrite in any of my tanks. Only a small amount of ammonia and varying amounts of nitrates.

[@australestarr]

Thank you for this explanation, it was very useful to help educate our 9 year old about the why's for caring for his new fish tank.

[@joeestes4958]

Perfect way to explain! Thanks Cory. Saving this video for whenever I am asked about the nitrogen cycle.

[@ejfishes7610]

Thanks Cory appreciate the information in that forum!

[@Sarah-oh8si]

Thank you so much for this video and explanation. I have just started working at a pet store and have no fish experience. I need to learn and this was amazingly helpful, cheers

[@Coronakenify]

Peanut M&M's -- Life is Good !!!. You hit it out of the park again. If I owned a LFS this would be required viewing for any first time fish buyers.

[@nevermindlaughs]

we don't deserve you cory lol , thanks for all the help you and the aquarium co-op team deliver time and time again.

[@nevermindlaughs]

bonus points for being legit and keeping the mistakes, point very well made, stupid clear, love this video

[@catlash3540]

This was awesome. It helped me and my kids understand better

[@rcampbell456]

I got a new tank and plan on populating it with native sunfishes I catch and some plants. I am going to try and use the local lake water, rocks and soil in the water and mix it with aquarium ready treated tap water to top off the tank. Do you think this will work in helping with the introduction of beneficial bacteria being that the lake water and rocks should have some? I understand this will introduce algae as well probably, which isn't a problem to me since a little algae should help process the nitrates until the plants take control and I can introduce some algae eating animals.

[@erxkeel]

dammit, now I want candy,

[@sabrinamoore6551]

this is such a helpful video when trying to understand nitrogen cycle!
