Hi all. New to group. Found site while trying to find a way to lower TA and raise ph.
Seems an aerator/acid is the way to go but . . . I removed the eyeball from my return and took it to local HD to make sure I had right size. Seems my eyeball is between 1 1/2 and 2 inches. It won't screw onto any of the standard 1 1/2 or 2 inch male pvc fittings. I guess i thought i could just buy 1 1/2 or 2 inch pvc pipe and various fittngs to make a home made aerator. Is there 1 3/4 size pvc fittings? (or any other bright ideas?)
