Thinking of upgrading the lights from 250-400

[Doug]

Why do you think the tanks lacking light now Mike? It was fine when all sps. Should have kept the 3rd halide.

I think if you want more light, go with a pair of vho super actinics as we discussed. IMO, that will make those lps colours jump out.

Or could always change the bulbs to a higher par type bulb but then the tank will be a whiter colour. The best combo would be a nice crisp 10k with a ton of par and a set of those super actinics to give it the blue type look.
