Hamilton Cebu 250w or 400w

[Rick55555]

Hi,

I'm thinking about purchasing a Hamilton Cebu 3 ft. with T5 and I am not sure whether to go with the 250w halide or the 400w halide.

The fixture is intended for a 90 gallon (36 x 24 x 24) SPS tank. I have a couple of LPS, but 90% of the coral are SPS.

I was thinking of running a Radium bulb. I forget which ballast is best for a radium - Magnetic or Electronic?

The 400w seems like overkill. Thoughts, please.

Thanks,
Rick

I'd go 250's, you'll be fine. I ran my 250 Radium with a electronic Lumateck selectable ballast. I ran it on the HQI setting. Looked great.
