4200k Mh

[lonestar]

Does a bulb this low in the spectum definately have no positive effect on coral growth. I have 2 smaller tanks (75 gal and 55 gal). They are both filled with live rock and sand and 1 is full of corals. I want to combine both of these together to put in my 200 gal tank. I have 6 VHOs that i can move as well. I will have 24 inches of water to light up (above the 6 inches of sand). I went today and purchased a few mh ballast. I really can not go and buy 3 or 4 of the 6500k iwasakis right now. I was just wondering if running 3 of the 4200k mh and 6 VHOs (3 blue, 3 white) over 24 inches of water would work. If the 4200k gives no positive effect at all, I might as well just wait till i can go buy the right bulb.
Thanks,
Jeremy

The 4200 are 21.00 each. They are also within driving distance. I would have to order the 65s. I only bought 1 of the 4200k bulbs just to see the effects of mh compared to vho. I do like the ripple look. If you all think that it will have negitive effects if anything, i will not even put 1 on my tank.
Thanks
