hey, just wondering if anyone had any pictures of their diy co2 injectors? I'm mostly curious about the placement of the air stone and line it's run on.

thanks,
adam

You should hook up your airstone to some kind of reactor even if this means just putting it under the filter intake.

If you just letting the CO2 bubbles rise to the surface you aren't getting the best out of the CO2 injection.

I've been experimenting with the placement of the airstone and I found by putting it directly into the filter (under the filter sponge) you can really increase the concentration of CO2.

Check out my post in the DIY fourm for more info if your interested.

Well, I have a wet/dry filter running on my 75 gallon planted tanks (I know that wet/dry's are not the best filters for planted tanks.) I have 2 DIY co2 bottles running. I stick the hoses into the intake of my pump, and the pump churns the co2 into fine bubbles which is pumped into the tank. It seems to be effective because my plants really took off once I did that.

See? lol Laughing

OK, I think that sounds like a good idea. I will try that.

thanks fish boy!

Yeah I connect the tube from the CO2 bottle to an airstone which sits in the intake pipe of my filter. Seems to work fine.

I just have regular old play sand from lowes.......But I think there is another factor helping the plants. I have enough sand for a deep sand bed in that tank. It allows anaerobic bacteria to form, which convert nitrate into nirtogen gas bubbles. I have to stir up the sand every week to get rid of these, because they can harm fish. BUT, the plants love the nirtogen gas, so I am pretty sure that is helping them along with the CO2.
