Does your filter pressure rise just a few days after backwashing, while the water still looks a little dull despite perfectly balanced chemistry? Your filter media is clogged with oils and grease that backwashing will never remove. Sunscreens, lotions, body oils, and organic residue eventually coat the grains of sand or the folds of the cartridge. Regal Filter Cleaner dissolves this residue and restores your filter’s true capacity.
Backwashing dislodges dirt; it does not degrease. That’s why a filter that has never been chemically cleaned can lose much of its efficiency while still looking clean.

How to track your starting pressure
Note the pressure on your gauge when the filter is clean, right after cleaning. This is your starting pressure. When the reading rises about 7 to 10 psi above this value, it’s time to backwash. If the pressure rises faster and faster each time, it’s not just dirt—it’s greasy buildup, and that’s exactly what this product tackles.

Frequently asked questions
Isn’t backwashing enough?
No. Backwashing removes particles, but not the oils and grease that coat the media. Only chemical cleaning removes them.
How often should I clean the filter?
Once or twice per season for normal residential use, and more often if the pool gets a lot of use or pressure rises quickly.
Does it work on cartridge filters?
Yes. The product is suitable for sand and cartridge filters. The method differs: add it to sand filters, and soak cartridge filters.
Can I use it while the pump is running?
Follow the instructions on the label. Generally, the product should work without circulation to dissolve the grease, then be rinsed away before putting the system back into operation.
