My water is 46 ppm or about 2.5 hardness. I want to fill my 75 gallon with livebearers, especially guppies. I tried the Equilibrium and I hated it, it is hard to dissolve and makes my tank cloudy, as well as being expensive. After watching several of Cory's videos, I think I can get by if I use crushed coral substrate as well as some liquid Fritz Complete. I understood to use marine salt at 1 teaspoon per 10 gallons for the beneficial salt and all the trace elements and want to convert that formula to the liquid Fritz. Should this setup make my water good for guppies? Thanks!
