Hey Steve,
Looks pretty slick. So, the Sea Swirl is controlled by the controller to come on at a predterminded time every day? My guess is that there will be a few areas where detritus collects but it may not be a significant amount. Do you have a dosing pump to add your dechlorinator? Also hope your air pump is tied down so it doesn't fall in your water tank.
Can't wait to see it working.
