I turned the skimmer off, and took the carbon filters out of the milleniums and my watchman goby died, and my chromis are sick and now in QT with copper. I need to make some serious tank set-up changes....I shouldn't even be running a hang on filter with a saltwater tank....I have no room for a sump....and suggestions for new tank equipment that would help improve my water quality are needed...
Are there any hang on sumps, or anything that would work well that i could use? Also, i've been using regular tap water and putting dechlor and salt for my water and i need a good freshwater purifier. So if you can help me with any of these things it would be greatly appreciated...
