Water clarity is 50% water balance and 50% filtration. If the filter is not being run as often as it should be or if the filter is not working efficiently, then proper water balance will not solve your problem. Filter aids, such as, Sparkle Up and Baquacil Flocculent, can be added to help improve filtration. Clarifiers can be used in conjunction with filter aids to increase the size of the particles so they can be filtered more easily. In addition to chemical remedies, proper water circulation inside the pool is vital. Your returns should be pointed downward at a 45-degree angle and away from the skimmer to create a circular motion.
