The intex pumps works OK for general circulation, but as Pool Doc mentioned, they really struggle when trying to clear a pool after an algae outbreak. If your budget allows it, Intex makes a sand filter/pump combo, that would serve you well. Sand is by far not the best type of filter for clearing a cloudy pool (vs DE or a typical cart filter), but 10x better than the very undersized intex carts. That said...keep up you chlorine levels and keep the filter going as much as possible.
