I've got a co2 kit coming and I live in a very hard water area so I've been using 75% to and 15% tap ive got my ph down for sometime now and is currently reading 7 on a liquid test. When I start dosing the co2 people say aim for a 1ph drop? Is that only for the duration of the lighting period then after lights out it should raise 1ph again? Does the up and down of pH everyday affect fish? It's only a 70 litre maybe I should I'm for 15ppm? Just Val's,sag,crypt,hygrophila syamensis and anubias in there ATM.
Thanks in advance.
