I am on well water and I have tested it for phosphates and don't detect any.
I will check again. I have a countertop RO
unit. My ph is 4.0 in my well water
and it takes me a week to buffer it up to do water changes and that is a royal
pain! I have corals and fish and they don't seem to be bothered with it. They
look healthy. Chili coral polyps extend a lot, Xenia looks great, leather finger
looks good. I don't understand my phosphates. I put in a boy'd chemipure
filter bag yesterday and am trying that. His red slime remover WORKS!
