Hi all

Got a question that's been troubling me...

My PH is 6.1 after Co2 injection at 1.5 bps. KH is 1.

Using the CO2 chart, that is about 24 ppm. I know my KH is abit low and I have just added coral chips to increase KH to about 3-4.

Assuming I can increase KH to 3, and PH increase to 6.4 (due to the coral chips), is the CO2 then 35 ppm? or is CO2 still 24 ppm as I have kept in constant?

My tank is a 2 feet tank. I feel that CO2 at 1.5 bps is already adequate. However, I am tempted to increase the CO2 due to 24 ppm.

Please advise.
