So I noticed when I got home my corals aren't opened up, and my 2 out of 3 urchins have lost some spines, just some, so i tested all my water parameters and the only thing that is bad is 20 ppm of nitrates. but that is no where near enough to do anything weird to my tank, since it used to be at 40ppm everything else checks out fine, But I do notice since I got my skimmer that my water doesnt have a certain smell it used to, in fact it has no smell at all it smells like fresh mixed saltwater, and my collection cup is filling up everyday, it said the skimmer would slow down the less waste there is, and the skimmer collection cup is brownish water, but now my water seems so clean its like almost reverting back to cycle itself, plus my water levler system is adding about 1/2 a gallon a day and so my (salinity) or w/e is 1.120 hmm so right now im puting more salt into my tank but I turned off the skimemr for now I think my tank was doing fine the way it was and now that i tried to make it cleaner i disrupted the bacteria and all that stuff, anyone ever have this problem. it's the only thing i can think of.
