So I never used IAL in my betta tanks before and now that I have been, my pH has (expectedly) decreased. That's no issue as its around 6.2 or so. But now it doesn't match my tap water and I don't want to be adding chemicals to change it. Also even though my water leaves white crust residue, it doesn't test as having much buffering capacity.
What I'm thinking of is switching to Atison's BettaSpa, which has buffers in it. I would gradually switch over, to avoid quick pH changes. Then I was thinking I could add some to replacement water and let it sit for a couple of days. That way tank and new water would match and Es would have benefits of the IAL without the pH issues.
Does this sound like a reasonable plan? Other ideas that don't involve adding chemicals?
