As far as an awesome SPS growing machine since the PAR of 20ks are a lot less than 10ks.. how would this sound
3x 20K 250w (insert best suited bulb here)
2x Fiji Purple
4x ATI Blue +
2x UVL Super Actinic
That would be a very nice setup. I think with running the halides at 10k would be too much PAR.. With the 20ks I think it would be an awesome color + perfect PAR.. I am running the 72" so I have 8x 39w T5's
So I think Im going to stay with the stock ballasts based on DarG's advice. But if you were going to replace the ballasts what would you replace them with? I was thinking the Icecap would be the best of them all. Thanks guys I really enjoy the help!

Just be mindful that depending on the 20k bulb you end up, that's going to be an extremely blue spectrum. I'd look at 14k's and swap the Super Actinics for something else, Aqua Blue+'s perhaps if it were my tank. If a very blue spectrum is your thing though, you'll certainly accomplish it with that setup.
