Hey everyone, I have set up a 75 gallon tank to keep Angelfish and possibly one pair of rams and of course a school of cardinals. My problem is the ph and hardness of the water from my tap. Untreated my tap water is very hard and high ph and I want to know if I can safely lower both with peat and keep it stable. The water that the angels are raised in is about 7.2-7.4 ph and and a hardness level between 80 and 110. Any advice would be appreciated. Thanks
