low CO2 levels any good?
I've been reading that levels of 20 to 30 ppm of CO2 is recomended.
Is lower CO2 levels any good for a low light?
I was considering adding diy CO2 to my large tank just to get some CO2 in.
Will it be a waste or will it benefit even at a low level.
Lighting is 1wpg, tank is 550 liter.
