Good advice here.

MH/VHO combo is probably the best.

However, I've seen some amazing tanks/sps coral grown under only VHO or T-5s. With T-5s showing what I'd say was "more natural or standard" colors and growth patterns.

If I go SPS again it'll probably be all T-5s, or, T-5s and 2 bulbs of VHO actinics as I still think the VHO actinics are better at putting out "true" actinic than any other bulb.
