Thanks for compliment, chucke!
Nolapete,
I'm using 5 maxi 1200s for flow (2 on a wave timer) in addition to two mag 7s that run the skimmers in the sump. When the timer goes off, there's lots of turbulence right where the sps are.
The only heat problems I have are in the middle of the summer. I have a fan that cools the mh ballasts and a smaller fan that blows across the water when the lights are on. Temp is usually at 78 give or take a degree. I haven't seen the heaters go on, ever.

I was told that the mags produce heat, so I was wondering if that was so.
