Picked up some new wildcaught tigers from peru and was wondering how many people have had success acclimating there wildcaughts with water that was a ph of 7.5 or greater. My water is 8.5-9.0 out of the tap and then goes through a r.o. unit to make it 7-7.5. I've tried chemically lowering it to 6.5 but it will just bounce back to 7.5 in about 2 days. I've tried some driftwood with no success (must have been preboiled?) and I tried peat but doesn't work well and is very messy. So I gave up on lowering the ph. Just hope other people have had success at high ph.
