Hi, I was hoping you can give me some help with my sunsun. I cleaned my filter about a week ago and came home yesterday to what looked like a natural disaster in my turtle tank. its a 75 gallon tank about half full with the sunsun filter. I have been using it for about a year with out any real problems. So I assumed my house sitter just over fed and I completely drained the thing and cleaned it with just fresh water and cleaned the filter. I put poly and the green pad it came with in the bottom basket, green scrubbies in the middle and balls and rings it came with in the top. So I checked it this morning and the water is green and cloudy. What am I doing wrong here? Any help is greatly appreciated. The filter is still pumping so I am assuming its working. I was thinking that maybe I just killed off all the good bacteria and need to give it time to regenerate. Thanks for the help.
