I have tap water and my kh is about 16 in a heavily planted tank 29g with
diy co2, gh 12, ph 7.7, NH3 0, NO2 0. How should I go about lowering it
safely? I may know the answer to my own question but I am not a very
confident aquarist quite yet. But how about doing week water changes? Up to
what percentage would be safe to do weekly? My tap water has a kh of about
4. Yes I'm not sure how my KH got so high, my tanks only been set up for 3
months now.
Thanks for the advice in advance.
