can any one tell me what the effects would be on my co2 injection for my plants when i am buffering my tank water with crushed cockle shell or will it not make and difference
If you are worrying about pH being knocked down in a CO2 injected tank then you are going to waste a lot of time accomplishing nothing. The pH is supposed to be knocked down. It doe not affect anything. In fact, monitoring the fall of the pH is one of the ways we ensure good CO2. You really need to worry about CO2, flow and distribution, not pH, because it doesn't really matter.where i live we have a very low carbonate hardness and the ph and kh drops off over a few days and with running co2 its knocks the ph right down
