I used two brass fittings in making my top off. I read on RC that brass is made of copper. Well, I noticed something is bothering my ritteri. I checked everything phosphates, ph, calcium, trates, trites, ammonia, the works. Since I mix my calc with my top off water the fitting was sitting in a corrossive solution which probably made it worse. How do you remove copper or unwanted elements? Carbon or polyfilter or both? I did a water change yesterday and will do another one tomorrow. Any one else with some ideas. Can anyone validate the above...copper/brass.
oops meant to put this in the general section
