I have a Rena XP2 on my 46. It’s totally quiet, I clean it out once every 6 weeks or so. I use the supplied sponges in the bottom starting with the coursest first. Middle basket has Rena starz and Walmart polyfil in the top basket. If you go with polyfil do not get the fireproof kind, it’s treated with chemicals.
The water is clear and like I said the filter is quiet. I have to hold my hand over the spraybar to make sure it’s running. Maintenance is also easy. To clean, just unplug the power, lift the hose latch and remove the filter for cleaning.
When it’s done, just assemble the canister and replace it EMPTY. When you engage the hose release, the water fills the canister.
Good luck
Charles
