Hello, I have a 112 gallon aquarium and my Ph is around 8.0-8.2, and I have researched a lot on web and it has said that a stable ph is better that the right ph, this I believe but, the fish I am looking to keep are angelfish, bala sharks, dwarf gouramis, zebra danios, rummy nose tetras, and some clown loaches. All these fish thrive best in ph of around 6.5-7.2, so I wanted to acheive a ph of around 6.8, but I read that that can be very hard to do because it would be hard to keep the ph stable. So would it be better for me too keep my ph the same, or should I try and change it so my fish will do better and maybe even breed. Any suggestions or comments would be nice. I was thinking of using peat moss and maybe Seachem Acid Buffer to get to that ph level but I am not sure if I am wasting my money and if it will work. Thanks for your time and sorry about the long comment.
