DIY- ‘Swirler Stein’ pump rotation device

I recently built a rotation device that turns my Tunze 6065 pump 90 degrees every 15 or so seconds. This helps create random water movement in the tank and I’ve noticed less detrius buildup on the bottom of the tank and SPS polyp extension has increased(near the pump). The design of the device is very similar to a Sea Swirl, as seen in the pictures below. It’s also waterproof, once the cover is on, and uses only 4 watts. It works great so far. I’ll be building another one for the other back corner. Just need to figure out how to hide the power cord from sight. Below are some pictures and the link to built your own.
