Well I guess it is time to put some real effort instead of trying to have buyers remorse. I currently have a small cubeish tank. It's deminsions are 40w x 36d x 22t and made of acrylic. So I do like the tank but , I think I need to revisit the whole build shabang. It comes way too far out from the wall. So I am going to redo pretty much the whole thing. At this time I decided to let the tank go fallow while I figure things out. I think I will be needing a lot of advice as I am changing a lot of the way things were done . So first piece of advice I need are lights. I currently use a 400 w metal halide. I have in my possession 4 6" makers heatsinks. . I also have , I think 36 RB , 16-20 NW , 8 tv ( 417 nm) , 8 tv( 430 nm) and 8 OCW and all the drivers . I am thinking of adding T5 at least 2 but since a cube thinking 2 36" and 2 24 " if it is needed at all . This tank has a 4" euro brace around the perimeter as well as a 4" front back across the center . It is clear acrylic but still I am thinking that due to the depth of the tank and all the bracing I could probable still get pretty good coverage where the rock work is placed. By th way I am thinking mixed reef with fair amount of fish. Does the lighting sound ok , I really would like to u the items I have.
