Yep a 4 foot Lunar aqualight. about 6 months old according to the seller. I was thinking of runing Actintic(sp?) over the tank, as well as the moon lights (wow are they ever cool

) I am debating on getting a second 175 watt MH, or perhaps trying to upgrade to 250's or 400's. and building a canopy
if I removed the 10,000k lights do you think I could retofit 250 watt DE's in their place and just run the fixture?
