diy co2 for 55g

I'm switching my lights up to a I was thinking about making a DIY co2 system but wasn't sure how to build one. I'm aiming for low tech and don't use any ferts. Also, can Excel provide enough co2 for my tank because if it does, I won't be needing a DIY co2 system.

You might need six 2-liter bottles running to DIY yeast CO2. Not worth the hassle, imo.

Excel is not CO2. It is a carbon-based supplement that breaks down into a form of carbon plants can use. Further, you still need to fertilize even in non-carbon-dosed tanks.

I also don't want to change the ph too much. I have south american cichlids.

Wow!! That is an extremely strong light. I think with DIY Co2 you are going to need to raise it above the tank.

Oops I was looking at the 3w on you tube.

Can't wait to see updates.

You got me interested in getting that 1 too. I was aiming towards 1 with .5 watt leds.
