How do I soften the water for my Discus? I just put a water pillow in the filter. I have well water in my home, and I like to know what what would be a simple thing to do, since the eater has to be change frequently?
Lowering the pH:
1. The pH can be lowered by using a pH-lowering chemical (available at pet Shop).
2. The pH can also be lowered by plants and fish during respiration, when CO2 is exhaled into the water
3. Peat in a form of dried moss can also be used to soften and lower the pH of the aquarium water.
