I have a 10 gallon tank with 2 Glofish tetras, a black Molly, 1 Mickey Mouse Platy, 1 Sunburst Platy, and 1 red wag Platy. The ph is 7.0, the Alkalinity is 80mg, and my general hardness is only 30 mg
. The hardness is really low and the Alkalinity is low also. What should I do?? I'm worried about my fish!!
