a simple way to get lower pH water to put into the tap is to use part rainwater in your water changes, i assume people run it through a basic filter first (like brita water filter or something similar) then use e.g. 30% rainwater and 70% tap water. then you keep the goodness from teh tapwater but reduce the pH of it.

I would like to restate that leaving the water is probably the best option.

It is not a high pH that is affecting your fish, it is the fact that you are sending the pH from 8.2 down to 7.6 and then back up again to 8.2 in a sort timescale with some frequency.

Most fish tht have pH problems don't suffer from a constant pH a little outside their rnge, but rather from constantly fluctuationg pH where someone is attempting to maintain a non natural level through chemicals and additives.

Thats what I am doing but using mineral water instead

interesting, what water stats do you get from this water? i must admit it had never crossed my mind to use it!

I am using mineral water from Cumbria. PH, 6.5, ammonia 0 Nitrite, 0 Nitrate 20ppm. Unsure of KH or GH as I don't have a tester for these. The tanks PH has sat at 7.4 for over 24hours now. I am adding small amounts of this mineral water when I do water changes.
