I'm starting to lose my mind and want to change a couple of things.

I would like to know if the IceCap 250/400 would be too much light even if I raised it high enough that it wouldn't scorch the coral I plan on putting in there. Because if I have to raise it too high whatever lies on the sand won't be getting enough light. Or I have been looking at the Tek-Light T5 fixture which seems a little more practical and wouldn't be too much heat.

Also instead of modding my AC70 I would like to look into a 10 gallon sump (that's about as big a tank that would fit under my stand) instead. Only thing is I really have no idea how to build my own and any threads anyone could point me too would be great. Or if there are any lfs/other reefkeepers that could help me build one so I have a better understanding as to how they actually work would be great. I would be glad to compensate for any help. Thanks
