How much co2 do i need?
I need some advice. I am trying to figure out how much co2 i need in the tank. I have a 10gallon tank with 40watt strip light about 4 inches above the water. Plants are HC, HM, dwarf hairgrass, brazilian micro sword, and marsilea minuta. I dose ferts using micros and flourish NPK. I have a pressurized paintball system. Right now I have it set at 1 bubble every two seconds diffused using a hagen ladder (dont know how efficeint these work). I have a glass diffuser on the way so hopefully that will work with my paintball system because the regulator's max is 15psi.
A couple days ago I set up a drop checker using homemade 4dKH water solution. THe checker is still blue so I don't know if I have enough co2 in the water. My plants all seem to be growing alright, however I seem to be getting what looks like hair algae, which makes me think I don't have enough co2 in the tank. My pH is 7.4-7.6 and kH is 14degrees. So according to the "sticky" chart my ppm is around 15 which should be okay. Then why would my drop checker still be blue colored.
Anybody with a suggestion? Should I bump the co2 up to 1 bps? or wait until the glass diffuser comes to see if that does a better job of diffusing the bubbles?
