IceCap 150w or 250w ballast

[ashkeenon]

hi there

In need of a bit of advice weather to go with a 150w or 250w metal halide light system by icecap.

The light will be for a 36" length by 15"wide by 18"tall and i want to be able to keep Sps corals and clams.

Thanks

I have the 250 w and I am very pleased with them . If you are going to spend the money go with the 250w

250w will work better for your application. You could probably get away with the 175's since the depth is only 18", but 250's would be safer for clams.
