Aside from a bacteria bloom and excessive bioload, what may be some other reasons why an aquarium would get cloudy and stay cloudy for weeks at a time?

this was a customers tank... she had said that clarifier worked once, but not again.

Maybe sometimes it depends on the brand Clarifier. Sometimes they are bad quality and don't work. I have experienced many problems through out many many years with cloudy water. I would think to remove about 25% of the water. Or like I did one time: Just all together do a full cleaning like you would do monthly I guess. But when doing the full cleaning wash the gravel fully in nice hot water. And make sure there is no more debris. Or keep the fish out and use a gravel vaccum. The excellent Brand Clarifier I use is: Aqueon Clarifier. It works very well and I put out a review and for many other products. Or just buy a brand new bag of gravel. But you still have to clean it. Also remember to use your Water Conditioner and Clarifier, when refilling tank with water. ****** REMEMBER: you HAVE to replace the cartridge when your water is clear after you use the clarifier. Or you can replace the cartridge too, if you feel that would work, when your water is filled with debris, and it looks as if your cartridge exploded from debris overload

More information about the tank is needed. What size tank? How many fish and what kinds? Have the parameters been tested and are they in the correct ranges for the fish involved? Has the tank been cycled? Is she possibly overfeeding, or not performing enough water changes?
