So I did a water change Monday and added some calcium to the tank. (maybe the problem). Anyways I also kicked on the filter and kicked around the sand to allow the detritus to enter the filter. Then I changed the filter. I measured and the Nitrates and Nitrites were too high so I added this stuff I got at the store that eliminates ammonia, chlorine, nitrates and nitrites. I added a lot cause the freakin nitrates and nitrites would NOT go away. Anyways with all the stuff I added the tank is now clowdy, the mushrooms, anemone and zoanthids are now all closed up and unhappy looking, but the fish are perky as can be. WHat happened?? Also the protein skimmer started collecting white milky looking stuff that didnt smell like the usual "crap" that it takes up. When I get home tonight I will probably do a 90 percent water change and start over. I have a nano tank to put the animals in for now.
