I only have 1 clown but noticed today that he is just at the bottom of the corner of the tank swimming a little here and there but staying in the corner of the tank.My protein skimmer quit working about 4 days ago when i was on holidays, i shut it off and waiting for a couple of weeks to buy a nice one. When i checked my saltwater tub i mix my water in that i add new water there was mucus white strings in my tub like crazy.Of course that was after i added 5 gallons to my tank, my pump i used before must of had other stuff growing and making the tub and water have white chunks looks kind of similar to toilet paper in water after a while. I am not sure what i should do , i cleaned my mixing tub out and the pump that mixes it and dumped all the water from it out , i have a big shipment of corals coming tomorrow and don't want to kill them if my tank is in rough shape any thoughts or ideas? :(:(
