#ed_op#DIV#ed_cl#sorry about that fist message i didn't read that whole second paige of replys befor a wrote it but i guess you found the same problem i did. also if you find that useing a ph. buffer is not getting you any progress you might want to try adding acarbonate alkalinity booster to raise thealkalinity witch will in turn raise your ph better then ph. up and if your ph is low so will your alkalinity. also sounds like you need to invest a few bones into a good test kit befor getting more expensive fish. p.s i found a goos company is Seachem the product is called reef builder im pritty shur anyways it worked for me, not shure if its avalible in your area.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#also read you have chilling problems, lol i seem to have oposite i have to usea 300w and a 200wheaters in difernt areas in my 75 to keep it suitable over the winter.#ed_op#/DIV#ed_cl#
