Do I need a check valve or bubble counter on my diy CO2 setup?

Hi Anon,
I’d say yes to both. The check valve is especially needed with a pressurized CO2 system, not compulsory with a Bio/DIY-CO2. But a check valve can prevent you for water backing up and soaking your room.

The bubble counter is good in two ways:

  • You can check how many bubbles will go into your tank
  • If done right you can use it as a washing bottle – this prevents self made biomass to get into the tank

There are good tutorial videos for a DIY-CO2 System on YouTube, in this one, a washing bottle / bubble counter is included. I’d never go without washing bottle again. In my system I don’t have a check valve. 

Please keep in mind that Bio CO2 won’t be effective in tanks with more than 10 gallons.




Look at all those greens! A majority of the plants are coming along nicely although I am having troubles dosing my ferts. A huge amount of glosso started to die off which is killing me softly.

I’ve been busy collecting hardscape goodies which I’m itching to put in a cube tank I have my eyes on. If I do go through with the cube, It’s bye-bye to this guy (too much maintenance).

Hey do you know anything about CO2? I've heard it can lower the pH in an aquarium and I know betta fish can "adapt" to a high pH but I think mine is too high for that. I've also heard that a diy co2 system won't work in aquariums with a high pH so I'm kinda confused. Also, I just got some aquarium sand, so I'm excited to now be able to cap my dirt with sand! Maybe my hair grass will start spreading better. They have really long roots o-o

Unfortunately I don’t know anything about using CO2. The fast-growing stems aren’t really my thing, so I’ve never looked into it. aquarium44 should be able to help you with it! Best of luck with your planted tank!



Hi, yes CO2 will lower the pH value of the water. How high is your pH? If it’s really high you can use soil substrate additionally, it also lowers the pH by eliminating the carbonate hardiness in the water. But if you plan on keeping a Betta, be aware that you shouldn’t use a lid then (Bettas and CO2 is not cool when a lid is on the aquarium because the Betta goes to the surface to breath and the air under a lid will be full of CO2 which could kill your fish).

DIY CO2 is the same as pressurized CO2 but it has a higher maintenance because it does not last very long but you can do it for almost $0. Almost ;) The only thing is, Bio CO2 is not suitable for tanks with more than 10 gal / 35 liters.

If you want know more about this topic you can ask me specific questions :)

Thank you!

My pH? I can’t give you an exact number, because when I tested it using a high-range pH tester I didn’t get anything close to the colors the test expected me to get. I’d estimate around 9 or more. My parents had to use hardcore chemicals to lower the pH in our pool. It’s well water, very soft with a small amount of tannins.

I really have to have the lid on, but there’s also parts of it that I can remove so that the co2 can escape. Plus I have plants: two Java Ferns, some anubias, and a bit of hair grass (that hasn’t been spreading, another reason why I need CO2), so they’ll be able to absorb the CO2 and produce O2 for the Betta (and snail, if he makes a difference).

The (10 gallon) tank is dirted (miracle grow organic) with a sand cap. The sand is supposedly pH neutral. I got it yesterday and put it in last night.

Anyway, I do have a few questions if you don’t mind answering them.
What’s the best recipe and size container for the CO2?

Will an airstone work as a diffuser? It’s about 6 inches long. I can get a small one if I have to. I also have plenty of tubing and a check valve.

Totally unrelated to my water and CO2, but could I buy stuff at garden stores to put in my aquarium such as calcium, as long as there aren’t any harmful chemicals in it? What about organic fertilizers in general? Because there are zero pet stores in my town yet there are numerous garden and farm stores.

Wow, pH around 9 is … well .. high! Do you already have animals in that water? Maybe you should go for a lot of driftwood in your tank, like apossibletwin said in this post

Do make DIY CO2, you can watch a video on YouTube I find pretty good. I’d recommend at least a 2 liter bottle for a 10 gallons tank. For the recipe take a look at this article. I think you will need to experiment with that. If you use tab water make sure you use water around 60-75°F or else the yeast won’t react anymore (never use water with more than 75°F). Just go and try if it works for you – I gave up in Bio CO2 pretty fast because I am so fucking lazy lol 

There are indeed people who use air stones (something like this) as a diffusor and you should test if it works like you need it. Just put the DIY system onto the air stone. 

It’s a difficult thing using gardening fertilizer in aquaria. As a shrimp keeper I’d say no – for a long time no shrimp keeper fertilized their plants because it was said that the fertilizer harms the shrimp. There are now tested fertilizers which I use. On the other hand I really don’t know how certain fish react to that. I wouldn’t risk it. 
I use EasyLife fertilizer (Nitro (NO3), Ferro (Iron), Fosfo (PO4)). 
Maybe you can find a reseller online for similar fertilizer? 

Hope I could help.. Feel free to ask further, it’s the dialog which educates us both :)

6 ways to cool your aquaria

It’s summer and in some regions it’s hot hot hot. Here are six ways to cool down your aquaria:

  1. Keep your aquaria in a permanent cool place like a cellar or a room which won’t get so hot during summer
  2. Keep your apartment cool by using the A/C, keeping the windows shut during day and aerate during night when the air is cooler. Keep the shades shut so no sun will shine into the room.
  3. Lights off: Aquaria lights could heat up the water so keep it off during the hot days. Plants usually are ok with no light for about two weeks.
  4. No lid: If you have animals which won’t jump out of the aquarium, take the lid off the tank. Through evaporation the water will cool down. Fish tanks or shrimp tanks can be secured with a little grid but some crabs can shove the grid away. 
  5. Ice: Temporary cooling via thermal packs, ice cubes and supply water in a plastic bottle / bag or frozen water in a bottle are being put in the aquarium (DON’T throw ice cubes directly in your aquarium, shrimp for example can die). Not really suitable for aquaria which cannot be maintained the whole day because you need to renew the bottles/bags several times a day.
  6. Aim a fan at your aquarium (no lid of course). Through evaporation you can cool your water down. Attention: Secure the fan so it won’t fall into the aquarium. You can also use special aquaria fans for tanks.

There are surely even other ways to cool the aquarium water down. It’s better the keep the aquarium water at a steady level. Shrimp for example get a faster metabolism when kept in too warm water. Eventually they die faster. If you have tropical fish, you probably won’t need to cool your aquarium down ;) 

A good summer everyone!! AQ*44

Someone please tell me what this is! While I’m trained in large-scale aquaculture, my skills at keeping small tanks are woefully lacking. I’m hoping to start a planted tank sometime, and these would be a beautiful addition, provided they’re not super hard to care for or toxic. :/

I’m not a botanist either, but that looks like wisteria. Either way, I don’t think that’s what people normally put in planted tanks. Still gorgeous, tho.

Huh? This is no aquatic plants I think. But you know Pogostemon erectum can grow out of the tank and it’s emersed form can bloom in a beautiful violet :)
