I've been running into a cloudy water problem after water changes and dosing. I've been dosing nitrates, phosphates, flourish, and flourish iron after water changes. The water becomes cloudy and gradually clears. I have a non co2 tank into which I dose nitrates, phosphates, and equilbrium at the levels recommended by Tom. Water is crystal clear. I haven't done a water change yet on this tank.

I read some postings here and on APD and suspect that there may be an interaction with the iron in Flourish , Flourish Iron, and po4 since I have been dosing them at the same time.

Is this likely the problem ? Also If this interaction is producing iron phosphate does this mean these two elements are not available to plants when they combine ?
