Can I turn my filter cups into an algae scrubber?

[RyanHoan]

Hello!

I currently have a refugium section in my sump, but I’m hoping to convert it into a frag zone.

I figure that all algae scrubbers need is flow, lots of oxygen, hard surfaces, and light. My filter cups provide all of that, minus the light!

Has anyone ever grown algae in them/ on your filter floss in the filter cup? I have two cups, so I figure I can keep one as a filter and fill the other with rocks and put a light over it.

Here’s a pic of my sump layout:

Any thoughts are very much appreciated

It’s just gonna be a mini fuge lol. I don’t think it would work for several reasons. Looks like this would be a waterfall type scrubber and it wouldn’t work with submerged cups. You can experiment with putting an air stone/bubbler at the bottom of it for an upflow scrubber with a roughened up mesh screen in the cup but if it does grow algae the drain flow will prob loosen it up and drag it around your tank.
