Lowering pH - is it worth it?
My tap water has a pH of 8.2. I have zebra danios, an angel fish, a swordtail, a female betta, and some cories that have all adjusted to the high pH. I now have available to me some purified water that, when combined with equal parts of my tap water, will result in a pH of 7.4. The new water has been proven to be safe for fish and the water would not rebound since this is not an additive.
My question, though, is whether or not it is worth it to slowly lower the pH since the fish are now used to the higher pH. Would I possibly kill some of the fish by doing so, or is the lower pH so much better for the fish that it would be worth the hassle and headache?
Thanks for any thoughts!
