Gravity Filters

Compact Pond Sieve Pre-Filter For filtering bottom drains and pondless water features. Flow Rates up to 5,700 gph (95 gpm) For koi ponds: This compact pond sieve pre-filter captures fish waste and debris from koi pond bottom drains for easy removal. Placed before the pump, it improves the overall health and appearance of the pond by keeping the pump from passing fish waste and debris to the biological filter, maximizing bio-filtration efficiency. For pondless water features: This compact pond sieve pre-filter captures debris for easy removal from pondless water features. Removing debris from pondless waterfall features naturally reduces algae growth and helps maintain clean, clear water. Learn More
