http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=discus-ph#1 I have an 80 gal display tank with no fish in yet, i will stock the tank with discus and tetras. Is it true that Peat moss will reduce the PH of the water? if so will it continuously do it; will i have to remove it? will carbon remove the yellowish tint that Peat produces in the water? jhamil 2009-02-25 http://forum.aqua-fish.net/?topic=discus-ph#2 why do you think that you need to reduce the pH of the water? discus can live in a pH of 7.0, years ago it was the done thing to keep them in a lower pH of 6.5 but many of the tank bred starins do not need this. What is your current pH? mickey 2009-02-25
