We just tested one of these over a 40 breeder, and with one unit, the par around the edges is about 80, and towards the middle on the bottom, 200. Halfway up in the middle, it is 300, more results will be posted, for an sps tank, 2 units would be reccomended for a 40 breeder.
You'd be ok running one of these over a 65g (just a taller 40g breeder) for softies even to the bottom? I will have a 3" sandbed, so that'll help.
