Ok, I'm upgrading my noobie 10g to a 38g heavily planted, high bio-load, 2wpg T-5 community tank.
I want to get into CO2, but as cheap as possible.
So I have some questions.
-Can anybody recommend a specific CO2 system?
-Should I go manuel, semi-auto, or fully auto?
-How many bubbles per second?
-I haven't been able to find any DIY CO2 threads here, but if someone could give me a link it would be great.
-I also want this to lower pH a bit, my pH is around 7.6 now and I'd like to get it below 7.0, is that possible?
Thanks so much everyone!
