    Does anyone know if using a tap water filter or purifier will lower pH and/or hardness? I have extremely hard water were I am but my pH isnt that high at 7.6 out of the tap, 7.8-8.0 in the tanks. Was just wonder if this would help to remove harmful things that could be the water along with lowering hardness levels.

    A reverse osmosis filter would do the trick for you. They remove almost everything from the water including minerals. You would need to remineralize with a product like Seachem Replenish.

    If you are talking about the cheaper filters like a Brita or carbon filtration than you wouldn't see much change.

    The filters we have strip everything from the water. I don't use those ones for the tank because I couldn't keep things in balance and went back to normal town water.
