So I'm trying to determine if Clams will be happy in my tank down the road here. I've kept many clams successfully in standard 55g and 75g tanks with 250 W 14K MH's over them. This tank however is different in that it is 30" deep. At 30" deep running 250 W 20K Radium MH's... clams on the sand bed? Nothing I'm doing soon but wanted to get the BAR experience on this if any.

Don't have personal experience with this deep of a tank, but I have seen others threads where they raise up their clam on the rock work to meet the required lighting needs. Would this be a possibility for you?
