But, I think the 15" would be fine for the corals.

Try the yo-yos they sell on fleabay for folks growing "medicinal" drugs. I have them and they work OK - not great, but OK.
I will have to take a look at these and how I could incorporate them into the canopy...Bill, I remember your set up...you wouldn't happen to have that seller's Id on ebay would you?

I measured the reflectors and they are 6" tall...so it would sit 9" (on a 15" hood) and 12" (on a 18" hood) off of the water..the tank itself is 24" from front to back, so I still have plenty of room to get in there and move things around as needed.

The 12" canopy is now no longer being considered.
