I picked up a fresh Brita water filter yesterday, and have been using it to do some minor water treatment. I noticed something - the pH drops from about 8.5 to a near-perfect ~5.8 just going through the filter.

Does anybody else experience this? I typically just use straight tap but I'm willing to roll with a water change, and at least filter it before adding nutes. Looks like if this keeps doing what it does, all I have to do is add nutes after filtering, no pH down required!
