PRODUCT FAQ'S
Yes, you should clean your filter after adding Phosfree and letting the system run continuously for 48 hours (while keeping an eye on filter pressure to ensure it doesn’t rise about 10 psi over start-up). You should also ensure that the filter is clean prior to starting a Phosfree treatment which will allow the product to work more efficiently.
While these products can assist in the stain removal process, they are also need to be used as maintenance treatments. Metals that cannot be fully removed through the filtration system (especially in sand and cartridge filters) are kept in suspension by Metal Free or Scale Free. Calcium molecules are deformed so they can’t stick together to form scale and other metals are kept in solution so they don’t settle back on a surface to cause recurrent staining.
Yes, vacuuming the pool surface thoroughly and cleaning the filter are two very important steps in the stain removal process that cannot be skipped. Cleaning the filter helps to remove some metals from the water. Others that cannot be removed are kept in suspension with maintenance products like Metal Free or Scale Free.
