KH and GH
Hi there, I bought a used 50 gallon tank, and the previous owner told me I need to use Aqua Vitro GH Mineralize and KH Carbonate.
He was running a DIY CO2 setup. Is it necessary to add these to your water every time you do a water change. I have not found anything on the net regarding adding these to a tank. Any help would be greatly appreciated
