C'mon all you Co2 experts...answer me this one,
How much is too much.
Can Co2 be a bad thing.....so we've got heaps of light and heaps of fertilizer and heaps of Co2 pumping into our planted tank...does this...at some point...become injurious to our fish. If so when???
I'm just about to go out and spend the big bucks to set up a heavily planted community tank...so I REALLY need your advice.
Help me, you lot. Please.
