    Here in my area the water PH is 8+. My question is if I run it through a carbon filter, Just like the bottled water companies do. Will that lower the PH or will I still have to adjust? The filter will get out all unwanted chemicals and inpuritys But does that change PH.

    I've heard people say that using a carbon filter to filter the water somehow jacks the plants up. I can't vouch for that, but I know I've heard it's a no no. In any case I doubt it changes the PH. Filters simply filter out the disolved solids.


    The best thing you can do is add some dolomite lime to the soil itself...this acts as a PH buffer and does a very good job of keeping the PH neutral. If you still wish to adjust the water's PH then I suggest using 'PH Down' or look into natural ways to lower PH. The search feature here may land ya some valuable info that's already in the data banks. :ebert:

    I put my tap water(7.8) through a brita filter and it comes out 4.5 1/2 & 1/2 makes 6.7.. perfect.

    I use a reverse osmosis system and it lowers the waters ph.

    Dursky...have you noticed any adverse effects on the plants using filtered water?

    I also use a carbon filter on my water. It lowers my PH from around 8.0 to 6.5. Add the nutes and my PH is a perfect 5.5 (for hydro).


    To answer Herb's question: My plants have had no negative affects from using water filtered through a carbon filter.

    Thanks Alien. :ebert:


    My water's PH is so low already that I would be a fool to filter it with my carbon filter....on the other hand...sounds like it's a great thing for those with high PH water in that it lowers PH.
