I came back from a 5 day vacation and when i came back one of the 5 1/2in gold fish was eaten. nothing but bones left and my tank was Horibly cloudy. i put in some "AmQuel+ plus" in my tank to remove the ammonia from the dead fish. the next day I bought some "Clarity" water clarifier in it and the next morning it was clear and i changed the filter floss like it said but later that night it was just as cloudy as b4. So the next day i changed 50% of the water and it cleared up just a bit and yet again it got cloudy later that day. Dose any1 know why this is and/or what i can do to clear it up????
