i got some sad news to say for my 55 gallon tank ??? I did a 50% water change due to cloudy water and hooked up my new rena xp4. I moved around some decorations so i could hide my java moss that keeps getting clogged in the filters intake. Filter on pumping super fast yet cloudy still and lost about 20 convicts??? i went on rena site and ordered a lot of filter media and a new test kit as my old one got ruined. So i am at a stand still right now with no idea what the problem is. Only the convicts seam to be coming up and staying at the top but everyone else looks fine. Anyone have a similar problem or any ideas?
