that's going to be nice 10' long with tons of real estates, not to mention external overflows. I went with tradewinds 18,000 BTU 1.5hp, which is the same brand unit I have for my home. currently my unit comes on 2 times a day and 3 deg difference keeping my water temp 79-80 that's with total 6 pumps not to mention a large skimmer. how much room will you have with the doors open front of display and the height of display? oh did I leave out plumbing, pvc cement and don't forget the face mask. very impressive build and keep things rockin' with pics.
