Biodegradable Urns : Fluval 3/404-3/405 Impeller Cover for Straight ...
I keep replacing these stupid impeller covers because the clips keep snapping and don’t hold the impeller in place, causing a loss in water pressure and a horrible clicking noise…But the Fluval is so good that I keep buying these things by the... the clip breaks…It’s becoming harder and harder to find these pieces, and i’m terrified that i’m going to end up replacing my 404′s when I can no longer find this part… That will be a sad day…. Every time… The pressure becomes too great on the impeller, the clip weakens, and SNAP.
