Recommended PH, GH, KH for Discus

Breeding 5.5 6.5

I would avoid buffers/additives when keeping discus; unless, they exceed the ranges above. Discus love good clean consistent water quality, so be careful of even slight fluctuations when performing water changes.
Note: Some PH buffers increase phosphates in your water and promote algae growth.
Hope this helps!
