Any advice for how to balance pH and hardness? I have low pH, lower than 6.4 on the Coop test strips, but very high hardness, close to 300 PPM.
I don’t think most of the fish are affected, but I have a tank of guppies and black neons that always seem to be struggling. The posted image is from that tank.
I have Indian Almond leaves in my two beta tanks, not sure if that will help these guys as well?
I appreciate the help!
