The answer is… it totally depends on your well. Discus fish like to be kept (optimally) at a pH of 6.0, a hardness of around 60-120 ppm TH. So keeping in mind there is a huge variation in water chemistry depending on the geology of the surrounding area. Generally the water in wells tends to be of a higher pH and hardness. Another factor with well water is surface run off! Discus fish as well as any other tropical fish do not tolerate pesticides or herbicides in their water… Generally after a heavy rain pollutants work there way through the ground into the well and in up in your discus aquarium. This can lead to stress, causing the discus to quit eating properly, loss their normal color or possibly even die. The solution to this problem is run your well water through a Reverse Osmosis (RO) filter… these filters remove up to 98.5% of contaminants from the water. This leaves a pure, pH balanced(water comes out of the units at around a pH of 7.0) softened water… perfect for your discus aquarium!
I am often asked… Is well water OK to use for Discus fish aquariums?
