I have a tank with only guppies that I have had setup for two weeks with now 8 guppies. I tested the water and the water hardness is very soft but the ph is alkaline at 8.4 which is the highest the strip will read so it could even be a higher ph. My question is since I have guppies I know the water is suppose to be medium hard to hard so what can I do to make the water harder without raising the ph?
Also how who aquarium salt change the results because I bought some but have not added any yet.
Thanks
