The Easiest Way to Get CO2 into Your Aquarium - Passive CO2 How To Guide

[@NateK-MN]

GREAT video. Thanks for implementing what Ocean Aquariums introduced to the world and making it more accessible.

[@BlakesAquatics]

Thanks Nate 👍

[@AussieAquatic]

I find the Sodastream CO2 really easy to find and low cost enough for me. Passive is super easy and is a simple step in the right direction :)

[@BlakesAquatics]

Yeah i was tempted to use one of my normal keg king co2 bottles but the sodastream is so portable and easy

[@marypaigeflynn4512]

Hello Colin, I'm always happy to see you. Hope you are well 🤗 this is one of those times that I slap myself on the head like 🤦 why didn't I think about this one 🤣 looks like a possible project coming up soon!! I hope you're having a very blessed day my friend!💚🌿🐟🌿💚

[@CoolTies]

What a creative idea and seems better than the passive Fluval kit I purchased in the past. Thanks for sharing!

[@GuadalupeGuacamole]

Love this idea…where did you get the clear rectangle container?

[@BlakesAquatics]

Just from kmart

[@plumber1331]

Great video..thanks.. going to give it a try

[@1blanchett]

This was sooo easy. Literally took 5 minutes now I've got co2 running in my tank

[@MHAquaticsUK]

Great stuff Blake!

[@micahagresta]

good video!!! keep up the good work.

[@AussieRic]

Easy & Awesome stuff !!!

[@DanielKeepingFish]

Good passive Co2 explanation video bud. Easy to understand for someone new looking into it.

[@aquaaz3568]

How do we connect a 4.5 kg co2 fire extinguisher that's sounds like a out of the box idea

[@BlakesAquatics]

There are adapters you can buy on ebay 👍

[@aquaaz3568]

@@BlakesAquatics I'll look into it thanks. Awesome video had me super intrigued

[@chriss1609]

Thanks for the video Blake, can this be used on a 55 gallon set up? I don't want to use injected co2.

[@BlakesAquatics]

Absolutely it can 👌

Cool idea, great work as always

[@bbbaa2706]

Hi Blake, thanks for your creative design of CO2 equipment. Wonder how to manage the amount of CO2 into the tank per second? For example, Steel bottle CO2 connected with diffuser allows us to set 1 bubble per 2 seconds.

[@BlakesAquatics]

hi mate, the way to control how much dissolves is to limit the surface area, smaller opening equals slower diffusion, larger opening equals more co2. cheers for watching

[@bbbaa2706]

@@BlakesAquatics Thanks for your kindly reply. About the surface area, do you mean the size of transparent container which attached to the fish tank?

[@BlakesAquatics]

@@bbbaa2706 the size of the opening 👍

[@inevitability3269]

Good video, Blake! I like the idea of a little extra co2 for the plants. not looking for maximum growth, just a boost. Would you say this is mainly for smaller tanks?

[@isaiahfreeman8734]

Thanks for the info! Also, what’s the name of the song that’s playing throughout the video?

[@BlakesAquatics]

Thank you! Sorry to say I cant recall. It would be a copyright free track from epidemic sound, you need a subscription though unfortunately

[@isaiahfreeman8734]

@@BlakesAquatics No worries, thanks for the reply!

[@Les-OZZYTHEOSCAR]

Really good video b!ake , would love to give this a try one day

[@dylanb9277]

Could we use a small container and only fill lightly to control having a small enough amount of co2 in the container that it diffuses over the course of the day rather than staying on at night/lights off?

[@BlakesAquatics]

The co2 will dissolve until it reaches saturation point. A smaller container will just fill/ empty faster

[@dylanb9277]

@@BlakesAquatics I figured as much, so if I find the right size container I could fill in the morning and it would ideally empty itself before lights off (erring on the side of caution)

[@BlakesAquatics]

@@dylanb9277 yes

Now I wish I had kept the soda stream I wasn't using.

[@kathydoro1527]

Wow great idea

[@BlakesAquatics]

Thanks 😁

[@rolfkarlsson276]

Dunno if it would be a problem, but if you have corys, bettas or other labyrinth fish, I would not use this method. Since they gulp air and use haemoglobin just like us, my guess would be that you could kill your fish if they decide to gulp from the wrong place. Co2 is toxic in high concentrations, not just oxygen displacing. Maybe just a net or something permeable would fix this, or if not needed, alleviate some anxiety.

[@BlakesAquatics]

@@rolfkarlsson276 yeah just placing a foam block at the opening would solve that

[@gotfoodstamps]

Can you blow in the tube if you don’t have a co2 pressure bottle ?

[@BlakesAquatics]

It wont really dissolve into the water unless its 100% co2

[@yenriver5255]

totally agree something is better than nothing..

[@VyvienneEaux]

That’s a really nice plastic container!

[@marypaigeflynn4512]

"Lifes Betta" with Blake and these awesome videos and projects!! This one's got me stoked! Guess what I have a sodastream that we never use, been sitting up on a shelf for over a year 🤔 it's my daughters... but guess what it's about to be mine 🤣🤣🤣 thanks for the video Blake, As always, I enjoyed it.... I hope you've had a good start to your work week and I hope you have a very blessed day!!🙏😁🌿🐟🌿💚

[@BlakesAquatics]

Thanks Mary 😄 good luck with it

[@edstar81]

that's a great idea mate. Thanks for the video :)

[@chevyfish4028]

I do like the passive method better and believe it is safer despite not being able to be turned off at night.

[@BlakesAquatics]

It definitely has its benefits far less wastage as well
