Co2

I have a 30 gallon tank with about 4.2 wpg. My plants usually grow pretty well and i am pretty liberal about my maintanance and fertilizing the tank.

I just wanted to know if two 2 liter DIY co2 bottle is enough for the tank. I do have small amounts of cyanobacteria on the glass from the start of setting up this tank but it is a problem you can't see unless you are very close up to the glass and it dies off and then comes back every once in a while. It usually dies off around water changes and picks up whenever my tank gets stirred up.

I'd say that should be more than unough. I only use 2x 2liter pop bottels on my 75 gallon, and it dropped the ph by about 0.2

75 gallon, fillstar xp2 with inline reactor, 12 Lb pressurised co2, 4.2 WPG-corallife 3x96 watt PC-, fluorite/silica-sand substright.

4.2wpg is pretty high doesn't leave you much room for error. Your going to have to keep the co2 up with fresh batch of yeast and sugar. Its up to you how much time you want to spend mixing up new batches.

I got pressurized in my 55gal and love it.

I used a yeast mix on a 30 gallon / high light with no problems. Pressurized is just more consistant and mess free but Yes it will work.
