I'd use a small sheet of plexiglass that I drilled or cut holes in personally. But if you have access to a 3 d printer you might be able to make something customGood morning all!
How should I separate my roller mat and skimmer from what I'd like to be a small fuge area? This is the sump for a Waterbox FRAG 105.4 the I removed the sock holders from, dimensions are 28.3"×17.7"×15.
Top left is for the return pump, top right is an ATO reservoir.
I'd like some rubble or biomedia and chaeto for nutrient export.
