We've never seen any evidence that Zeolite was better than sand -- though it's much better than MISSING sand, if a filter has gotten low, because the pump is too big for the filter.

MOST of the causes of cloudy water are biological (algae or people 'goo') or chemical (calcium + carbonates, or other bad chemical mixtures) in origin. Once the cause is resolved, the speed of clean-up is determined by your filter.

But to even begin to help you, we'd have to have some idea of what your chemical situation is: what have you added, and what are the current chemical levels? A VERY common cause of problem is high stabilizer (CYA) when pool owners do not understand that their chlorine level has to be at least 10% of whatever their CYA level is. Pool stores don't help, because they refuse to sell the K2006 kit which allows accurate measurement of CYA levels, and FC levels over 5 ppm. (See http://pool9.net/tk/
