The hydra52 is supposed to have a 36x36 spread. The only way I noticed that it does if its mounted like 2 feet above the water. I thought 2 hydra 52's would suffice a 60" area but I did not like the spread so I had to use 3. Its more like a 30x30 spread 1' above water level.
Other than that.... I like it :bounce:
