You need to get something that makes the particles clump together so the filter can filter it out https://a.co/d/09RpZp0D I rec this. What you have is residual biological skin and oil sweat and laundry detergents your filter cannot filter out I recomend you have guests and anyone else but your family really rinse themselves off prior to use and dunk there swim suit in clean water as they all have laundry residue on them. A product like above clumps these bio chems together so that they become bigger in particle size and your filter can remove them “Water Clarifier’s powerful liquid formula attracts water contaminants too small for filters to detect, allowing these small particles to become large enough for spa filters to trap and remove, restoring water clarity.” That’s a swim spa the water is balanced and you said you had a bunch of kids in it for 5 hours. Makes sense. Heavy use typically needs a little extra attention than standard maintenance. If the water is “fresh” aka not months old there’s no reason to do a drain first when the issue can be remedied easily with one product. Cmon folks Exp a swim spa thag thing likely holds 1000+ gallons
