Waterbox 90.3 Sump Setup - Filter Cups with Poly?

[Ian Bollinger]

Setting up my WB 90.3 and not a fan of the filter socks. Water likes to drain down the gaps of the cover plate instead of down the socks. I was considering a fleec roller but the reliability concerns along with noise swayed me to filter cups. Hoping for some insight:

- What polyfil do you guys recommend running and often do you find yourselves replacing it? Looks like walmart has some good deals..
- Do you run anything else in the cup like a filter pad of some sort? Considering cutting out a thin pad to place overtop the cups for noise and prevent water from draining down sides
- Open to any other insight or suggestions

Plan on running some carbon and occasionally GFO in a separate BRS reactor in the sump. Getting back into the hobby after about a 8 year hiatus and lots have changed.

Thanks!

I ran this stuff for a while and purposely left it loosely in the cup because I did not want to filter 100% of the water going through. Better for copepod populations to allow a path between sump and display without mechanical filtration. Changed every few days. Much more convenient than cleaning socks.

I’ve since switched to a reef mat and teed my drain to a refugium that bypasses the roller for my pods. IMO the reef mat is by far the best solution if you can afford it and don’t have low nutrients. Super efficient and convenient. Very reliable and not really that noisy. It also has a setting to only advance at certain times so you don’t hear it.
