Agreed.

Bro uses a britta and it only drops his tap water .02 or so.

I have 2 R/O filters and the water is almost the same after. 7.0 before and 6.8 after.

I have a hanna combo that needs the ph probe replaced for the scound time but 6 years old. Now I use a cheap milwalkie but they work very well and last as long as you don't drop them in water. And I know when it needs calibrating by always checking the R/O, it never changes.
LOC NAR on probation Reviewed by LOC NAR on probation on . Dramatic pH drop in filtered H2O? 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! Rating: 5
