I need to get a pH down from 7.2 to at least 6.4. any ideas?
bogwood? or maybe CO2? I think bogwood is the best way, but you could also use peat in the filter

i thought even with drip adjust the discus wouldnt be too happy. i have a huge peice of bogwood only lowered my ph 0.2![]()

i thought with discus though you would need R0 due to there dislike of tap water![]()
If it's a planted tank, just add some CO2, that will lower the pH. But the only problam you have is it could cause pH swings overnight. What is perhaps more important than the right pH, is a consistant pH.
I mostly agree with Anita, a ph of 7.2 is okay for discus, if your water is not too hard they should be okay, the only reasonably good way to soften water and get an acidic ph is to go the RO route. Just because stability is important. The discus eggs will only hatch in very soft water but young or adult discus should be okay in very clean water in a tank that is not heavily stocked at a ph of 7.2. Acclimatise them very slowly over a couple of hours or more if the water they are coming from is different to yours
