The Nitrogen Cycle! The most important aquarium info!

[@Laayoh]

This is one of the best beginner-friendly explanations of the nitrogen cycle. The most crucial part that I just didn’t get at first is that the cycle is constant and doesn’t just happen when you first set up a tank. I think the visual graphics and animations really helped, especially for someone like me who’s a visual learner.

[@FishShopMatt]

Thank you, that's awesome to hear. It took me a while to make the graphic so glad it's useful hahaha

[@SagasInStitches]

Thank you Matt. Now I know why I kept failing with problems constantly. First not enough water change and then too much cleaning. I never had it explained in a way so easy and simple to understand as you just did. I had a pile of aquarium books I just ended up giving away, because they weren't helping. Maybe you should write fishbooks as well :D

[@darrylmoore5847]

Since discovering KZbin fish videos many years ago I have watched lots of videos on the nitrogen cycle. Your video is one of the best. I find people either over complicate the subject or they treat the viewer like they are completely stupid. Thank you for making a video that will actually help a new fish keeper.

[@faedoyle4147]

I was an over-cleaner when I started. You’re such a great teacher. This is so perfect for newbies. ❤❤❤

Thank you so much, I used to clean too much too.

[@Guzmana895]

I've seen a few videos about the topic and somehow still don't fully understand. After watching this video now it makes perfect sense because you didn't just talk about the topic but you also mentioned not fully cleaning the tank itself keeps the bacteria alive in order to help you. Thanks Matt

[@thomasdeansfineart149]

Wow. Thank you. Perfect timing for me. My mature aquarium has seen increasing nitrate-to my surprise-and I’d assumed the plants and great filter would take care of it. The fish load has gradually increased because of fry born in the tank maturing. I thought water changes/filtration/heavy planting would handle it. Now I know better. Thanks again for this super explanation, Matt 🙏🙌👏

I'd have to say this may be the best explained and engaging video about the nitrogen cycle I've seen. And that's hard to do lol - well done.

[@MandyJane123700]

I had to make myself stop over cleaning my aquariums. I thought I was being the best fishkeeper, and didn't understand why I was getting bacteria blooms. Now I know some things do need cleaning, but I try to never do everything all at once, and I've learned to appreciate all that life in there is important.

[@FishShopMatt]

Exactly, there is definitely a level you need to clean too and then stop. I was the same as you when I first started fishkeeping though.

Matt, good explanation for the new folks and vital info for everyone to remember. Understanding nature is essential. Nature is not a sterile environment. A tank without plants (unless fish dictate otherwise) is going to always be a challenge to maintain good water quality.

[@wa77os79]

Some pet shop outlets are to blame for the lack of knowledge given to customers who buy a tank setup. Ive been sorting a mates tank out for him,they bought the setup,then bought some fish for it(same time).angel fish guppies neon tetras and harlequins.No one told them to Walt before adding the fish.nothing about cycling the tank.they set the tank up water,temp.tap safe. bottled bacteria and fish.BIG fish kill.nitrite levels though the roof.Now added some of my filter media and 10/15 percent of my water to his tank.I think shops need to ask the customer the question,do you know what you're doing..this might prevent fish deaths..top video.10/10..🎣

[@rossallen738]

This is a great simple way to explain part of the nitrogen cycle, and is how it is utilized for most people in the aquarium hobby. I'm an environmental engineer who has been through a number of classes that we talked more in depth about the nitrogen cycle. Nitrates can actually be broken down in an aquarium if it is built with nitrate removal in mind. Ammonia to Nitrite to Nitrate is all performed by nitrifying bacteria that breath oxygen just like fish do. Then there are denitrifying bacteria that will break Nitrate down into N2 gas and H2O. The N2 gas will then escape out of the water just like CO2 and other gases do. The key for denitrifying bacteria is that oxygen is toxic to them. They need anaerobic and anoxic zones to survive and they BREATH NO3 instead of O2. When they breath NO3 it is converted into N2 and H2O. There are a number of ways to encourage anaerobic and anoxic zones within an aquarium setup. By having deep sand beds that are undisturbed the denitrifying bacteria will have a safe haven that they can thrive in. Another way, that is likely more effective at removing all of the nitrates in the water would be to have a very large filter with very low flow. Another KZbinr explained this with graphics, but I can't remember the KZbin channel... Basically, the first half of the filter will have oxygenated zones and the nitrifying bacteria will do their thing, and actually consume all of the oxygen. The last half of the filter media will receive water high in nitrates, but 0 oxygen. This allows for the denitrifying bacteria to convert the nitrates into N2 gas and water. The trick is that the filter has to be designed in a way that it has anaerobic and anoxic zones to allow for denitrifying bacteria to survive. Denitrifying bacteria colonies happen to be very susceptible to change and can be wiped out very quickly if exposed to any oxygen and these colonies grow and reproduce very very slowly... A deep sand bed is the simplest solution. But it is paramount that the deep sand bed goes undisturbed so that the growing colony of denitrifying bacteria are not killed.

[@SeventyRS]

Fantastic information for me. Thank you. I have an older aquarium that has been having nitrate and algae issues and this just made it all click in my head. It's heavily planted and I do regular water changes but still couldn't quite get the nitrate level down enough. Bigger changes and lighter feeding are clearly needed.

[@WarrenS-t9c]

Thanks Matt, been a fish keeper on and off for 40 years and many things and thoughts have changed over that time. Working a two on two off (weeks) Im exploring alternative ways to reduce Nitrate. My tanks hsve to go teo weeks without water changes. Father fish has opinions on how much nitrate you can allow in a tank anf Dr Knovak has a possible method of removing Nitrates and competing the cycle. Im experimenting with dr Knovaks plenum at the moment. Just putting it out there that there may be alternatives to the water change as an end result. Enjoying the videos 😃👍

[@FishShopMatt]

Absolutely there are alternatives, I think the hardest thing is those alternatives can be unsightly or difficult to understand.

[@Chompchompyerded]

The plant that uses the most nitrate is corn. I've never seen anyone plant corn into their aquarium. Legumes (Beans, peas lentils, etc.) actually put nitrate into the soil, so never plant beans in your aquarium. I've never thought of putting lions or wildebeests in my aquarium, but I would like to raise rhinos in it. I've heard that they don't do well in water though. Maybe I'll go with something smaller like rams. Blue ones. Ewes are straight out. Only rams will do. There are problems keeping rams in tanks too. First off, their poo is absolutely gigantic compared to the size of the aquarium, second, the plants keep getting tangled in their fur, and third, they don't do much better underwater than rhinos. Dying the fleece blue doesn't seem to help either. Matt, can you tell me how to keep a ram underwater? I fancy a Leicester longwool to any others. I don't really care if it's dyed blue or not. What would you say the minimum tank size would be for one, and will it be aggressive toward my other fish? I want to keep corys and tetras in with it. Maybe even a khuli loach too if there's room. I'd also like to know what to feed it. Do you know? Also, does Maidenhead carry Leicester longwools, or is that something I'll need to get from the Maiden's Bum. the pub nearest my flat? If I have enough to drink there, I can see just about anything, but somehow I always come home bankrupt, and wake up in the morning with nothing to show for it other than a whopping headache. I really should not shop there as often as I do. Maidenhead has much nicer things. 0I wonder how hops would do growing in an aquarium? I've grown sweet basil, lemon grass, and even raspberry canes in aquariums, and I grow spearmint in my Oase hang on back filter (have it sitting in the big space just before the filter media, and leave the top off the filter), but I've never thought of growing hops in one until now. Not that it would matter. I don't know how to brew beer anyway.

[@nickdarke2138]

Great explanation Matt and ideal for any newbie aquarists. Historically, I've always been one for a slow cycle without resorting to chemical additives, building up stock levels over a period of several months (regular water changes and testing obvs). Mainly this was due to a lack of viable alternatives, but things are certainly different now!

[@FishShopMatt]

Thank you! Yeah I can understand that, I also slowly add fish but like the back up of the bottled bacterias.

Hi Matt, I'm a beginner and have started small (i.e. with a 25 litre tank). Got various rocks, a piece of redmoor and 3 different plants. Sand over a plant substrate. Done a fishless cycle and after bang on three weeks, water parameters were pretty much spot on, i.e. 0 for ammonia, nitrites and nitrates. Plants are all growing well btw. Your first suggestion on the control of nitrates is to do weekly 20-25% water changes. Each time that is done, should I put the required dosage of de-chlorinator and some more bottled beneficial bacteria (NT Labs filter starter?) into the 'new' water?

[@ricardotolosa2671]

Hi Matt, brilliant explanation. I've never realized that the cycling is ever going on.....then my question. Once the aquarium is good for fish, after cycling, does the amonia/nitrite/nitrate cycle starts over or the nitrite does not come again when you put fish there?

[@FishShopMatt]

Thank you, ammonia and nitrite shouldn't really ever appear in your aquarium once it's cycled but. When adding new fish, feeding lots, doing a big clean you can get rid of enough bacteria that there ain't enough to cope with the waste so you end up with a spike.

[@baldyspice220]

Hi Matt. Loving the vids as always. You and MD have inspired me to get back into fish keeping after a five year break. Currently building a heated fish room with 8 tanks and sump. Just want your opinion on something. Do you think it would be a bad idea to seed my sump in the heated fish room with media from my outside carp pond? Wanting to speed things up when it comes to adding fish, you know the score 😬😬

[@FishShopMatt]

Thank you so much! In theory there would be nothing wrong with doing this. The only issues would be if you were super unlucky and introduced a cool water bacteria or parasite. But I think the risk of that would be so so small.

Hey Matt. I cannot get the testkit you´ve recommended in Denmark. Do you know if the sticks with an app reader from JBL are good ?

I’ve just upgraded their tank, and I made sure to not clean any of the plants of hardscape that I moved from the old tank to new. I’m assuming this will have helped with the cycle?

[@katywi4534]

Matt, How do you get rid of brown algae? I had to dismantle my 55gal do to it. Miss it though.

Depends on the type of brown algae, could be down to nutrients in the substrate, it could be to little lighting. I would just keep changing things like more water changes, less feeding and changing the lighting until I see a difference in the algae.

[@maxine3587]

I'd be interested to know too.

[@FishShopMatt]

Personally I like sand but it can't be a fine play sand. The main reason being is sand has less gaps between it so fish waste sits on the surface where as gravel has bigger gaps and the poo and uneaten food can get in there. But really with the correct setup both can work well.

What about things that can add ammonia etc to the water? For example I am using a lot of pond soil and I've read that it can add ammonia to my tank which may explain why it's been cycling for a week with what seems to be 0 drop in ammonia? Should I water change to remove this or will that also reduce the bacteria too much? Edit: Tank is otherwise empty, a few stem plants, pots and gravel - Will be stocked with rams once it's safe.

[@FishShopMatt]

You could certainly do a few little water changes and as long as you don't disturb a lot of hardscape and the filter you should be fine. Eventually the filter should deal with this but it may leach ammonia for a while so it will probably be a waiting game.

Today another 50% added Beneficial bacteria again, just tested again and still high. Please help 😪. I have Anubias and Java ferns. Everyday another dead Swordtail 😔😪😪😪

[@FishShopMatt]

So there are a lot of things that could be happening. Firstly what is your ph? If you have soft water the ammonia can be ammonium which should be less toxic but still tests as ammonia. I've seen ammonium sit around in an aquarium for ages and not go anywhere. With the water changes you have done it should have cleared most of it. But you may find where you are adding the beneficial bacteria and if it's ammonium they may not have an abundance of food. This means the bacteria are dieing and then causing their own little spike in ammonia. It's a difficult position to be in and if it was me I would try a water change or two without beneficial bacteria and just use tap water safe. You could then use some ammonia remover filter media to absorb any ammonia that is in there. Hope this helps and makes sense.
