Remember, your pump, filtration system and UV clarifier work together to ensure clean, clear water and a healthy ecosystem.
Regular filter maintenance is critical to your system running efficiently. One clear indicator that your filter needs to be cleaned is a change in water flow. If you notice a reduction in water flow, it is time to clean your external filter and/or the prefilter on your pump. The methods for cleaning a filter will be different from filter to filter. Consult your owner's guide for specific information.
Remember: don't use untreated tap water to clean the filter
Untreated tap water contains chlorine and chloramines that can kill beneficial bacteria colonies. Use a bucket of pond water that should have already been de-chlorinated to rinse the filter pad or other media.
