lol, well- when I get ahead on my extreme picotope project, I will be looking into crafting a box type of cover for the rear sump- maybe utilizing the fan into the setup to help with cooling.
btw, nice setup! that is how I started- installed an ATO sump into the stand.
On another note- I almost pulled the trigger on a reef octopus external protein skimmer over the weekend for the RSM. Keeping my eye on the lookout for an external protein skimmer.- one less motor in the water.....
If the picotope extreme setup pans out- I may utilize an Auto liquid feed refridg system into the RSM. The Pico is the experimental guinea pig for the RSM.
