Ive been having having issues with my QT lately, I do 100% water change get it back to normal and within 3 days I have pea soup. Its driving me nuts cause its worthless to QT fish that you can't see to observe. Ive torn the whole tank down, cleaned everything, changed all media and 3 days later pea soup. I thought it was the window behind the tank causing this, so I blacked out the back and try and keep the blinds shut but no help at all. Thoughts, help anyone?
That's crazy. How is the QT set up? Any liverock, sponge or anything? Have you tried adding water from your display when you do water changes? Just grabbing at straws here I'm stumped too.
