For All Water Chemistries EXCEPT Soft Soak
Clean filter(s) are vital for circulation and heating systems to function properly. Cleaning your filter(s) every 4-8 weeks will produce cleaner, safer, water and will extend the service life of your filter(s) for up to one year.
Clean your filter(s) by following these five steps:
NOTE: If necessary remove calcium or mineral build-up by briefly soaking filter(s) in a separate acid solution. To make an acid solution, add 24 ounces of SpaGuard pH Decreaser to five gallons of water.* Mix thoroughly. Soak filter(s) in acid solution for 10 minutes. Thoroughly flush acid solution from filter(s) using large amounts of clean water.
CAUTION: Before soaking filter(s) in acid solution, all oils and cleaning products must be removed. Failure to remove all oils and cleaning products before acid soaking my result in a permanent restriction of water flow through the filter and cause premature filter failure.
REMINDER: Failure to THOROUGHLY remove all SPAGUARD FILTER CLEANER from filter(s) will result in foaming.
WARNING: Always add acid to water.
Do not mix chlorine or liquid bleach with acid.
Wear rubber gloves and safety glasses when using acid or chlorine.
