Cleaning Your Pool Filter
Keeping a clean pool filter is essential to maintaining clear water. Before breaking down the steps to cleaning your filter, it is important you know what type of filter you have. There are three types of filters: sand, cartridge, and diatemacous earth (D.E.). A sand filter contains either filter sand or ZeoSand as the filter media. A cartridge filter contains one or more white paper cartridges, and a D.E. filter contains large grids coated with D.E. powder.
CLEANING A SAND FILTER
There are three ways to clean a sand filter: backwashing, using a chemical sand filter cleaner, and changing the sand.
- Backwashing your sand filter is important to cleaning the sand of dirt, algae, and other build-ups.
- To backwash your filter, turn the pool off, turn your multi-port valve to ‘Backwash’, turn the pool on for about 2 minutes (or until the sight glass clears up), turn the pool off, turn your multi-port valve to ‘Rinse’, turn the pool on for about 30 seconds, turn the multi-port valve back to ‘Filter’, and turn the pool back on.
Chemically Cleaning Your Filter:
- There is a chemical designed to clean your sand filter.
- This half-gallon bottle, called ‘Sand Filter Cleaner’, is added through the pump basket and backwashed into the sand filter.
- Once in the filter, the pool is turned off for 8-10 hours to let the cleaner work.
- Then the pool is backwashed and rinsed, then normal filtration is resumed.
Changing Your Sand:
- Every 2-3 years it is necessary to change out the sand in your filter with new sand/ZeoSand.
- To schedule a sand change, contact our Service Department.
CLEANING A CARTRIDGE FILTER
To clean a cartridge filter, the first step is to remove the cartridges from the filter and rinse them off to loosen any dirt built up in the cartridge. After rinsing the cartridges off, it is essential to soak the cartridges in a cartridge filter cleaner. For more in-depth instructions, contact your local Hawaiian Pools retail location.
