RED SEA CO2 Test Kit
I've been following the CO2 chart that is based upon the levels of PH and KH and recently bought the RED SEA CO2 test kit to see if the chart is correct and just when I thought I had a handle on CO2, I'm confused again.
My PH is usually around 6.4 with approx. 1 degree of KH yielding a CO2 level of 12m/l (according to the chart).
According to the test kit, I do not have any dissolved CO2 in my tank.
I am using the RED SEA Turbo CO2 Bio System and have 96 Watts of lighting on a 38 gal. tank. All of the growth in my tank has improved dramatically since the addition of CO2. I have also tested the water at night and in the morning with the same results.
Does anyone have this test kit and if so, maybe point out something I might be doing wrong?
Does the relationship between PH and KH DEFINITELY indicate that one has CO2 in their tank?
