CO2 levels.....
Ok, so my PH is 7.5, KH 4 degrees, GH 8 degrees, ammonia, nitrate, nitrite
are all 0. I have crushed coral in my canister filter to try and raise the
KH, and have managed to get it up to 4, it was 0.
With the figures I have my CO2 levels are sub-prime. What can I do to
raise them??
My CO2 is a DIY and I am getting one big bubble every 2-3 seconds. This
feeds into a wood airstone that is placed below my filter intake.
