Lance's 225 gal tank

[Lance]

A very pleasant surprise today.
It's the first hot day we've had this summer and I discovered the new light fixture heats the tank less than the old one did even with the extra 570 watts. Huh! (Fans only went on a few times today for short periods, and the temp. never went above 80.8 F)
Because the 400W MH's have way better penetration I have the fixture 15" above the water whereas the old fixture, (Aqualight Pro), was only about 5" above. This fixture also displaces heat much better.
And to think when I bought it I was worried about the tank getting too warm!
