Enrich the water with minerals by using sera mineral salt if you live in an area with soft water. We recommend checking a few of the more important water parameters on a weekly basis – and correcting them if necessary. sera test kits work with liquid reagents, are simple to use, and can detect even small concentrations. We recommend the follo- wing sera test kits initially: GH Total hardness KH Carbonate hardness pH value NH4/NH3 Ammonium/ammonia NO2 Nitrite NO3 Nitrate
