Baquacil® Filter Aid is a highly efficient powder that increases the effectiveness of D.E. cartridge filters. This swimming pool D.E. cartridge filter aid helps the filter capture tiny suspended particles of dirt and debris that would otherwise slip through and return to the pool, causing dull water. These particles are so small that a filter, even in good working condition cannot remove them. If continuous filtration does not improve clarity and/or no rinse in backpressure is noted, the use of a filtration enhancer may be necessary. Baquacil® Filter Aid will assist the filter in the removal of particles too small to be trapped on the filter media.
Before using Baquacil® Filter Aid, make sure that the filter is clean and in good operating condition. For diatomaceous earth (D.E.) or cartridge filters, disassemble and hose off the grids or cartridge (s) to remove any loose dirt and debris. Inspect the grids/cartridge(s) for any tears or holes and replace as necessary. If grids/cartridge(s) appear dirty after hosing, clean with Baquacil® Filter Aid as per label directions before proceeding. For sand filters, backwash and inspect condition of sand. If the sand bed contains dbris, clean with Baquacil® Filter Aid as per label directions. Replace the sand if it is very dirty and caked together. Remove skimmer basket(s) and pump hair/lint strainer. If the pool is equipped with a suction type automatic vacuum, disconnect and remove from pool. Make sure that returns are pointed downward and open valves for skimmers and main drain (if pool is so equipped) to create a circular flow pattern. If pool is equipped with a timer remove “OFF Trip” to allow for continuous filtration during treatment. The filter should be equipped with a pressure gauge in good working condition. Under no circumstances should the backpressure be allowed to exceed the filter manufacturer’s maximum recommended operating pressure. If back-pressure rises 10 psi above starting pressure then either backwash or hose of grids/cartridge(s). If acceptable water clarity has not been achieved then repeat application of Baquacil® Filter Aid.
