Seems like whenever I take out my hot tub filter, some of the stuff that is caught in the filter comes loose and gets back into the water as I unscrew it. Is there a trick to this? It is disheartening watching all that 'stuff' go back into the water, there has to be a better way to remove these filters and keep all the stuff in the filter...without it breaking loose and getting back into the hot tub water...?
