Stop being a slave to the pump basket

Pumps and filters always work better with a solids separator ahead of the pump. The AquaSieve2 is a 12" x 27" high-impact, implosion-resistant vessel with a huge strainer basket and a clear lid — the leaves and debris that clog a pump basket in a day collect here instead, and most owners empty it every one to four weeks. The AquaSieve SS is the industrial version, new and heavier for 2026: heavy-gauge polished 316 stainless, 10" x 29", stainless basket with 1/8" holes, positive-seal lid and a water drain fitting — in 2", 3" and 4".

Use the AquaSieve before the pump and a MultiCyclone after it and you'll have the happiest filter and fish you can have. The 3" and 4" stainless units are what GC Tek specs on the MegaSystem3 and the big drum-filter builds.
