Thanks for your imput, to answer your question.
My current plan, feel free to critique
reef 48lx18wx24h I currently only have a 1" sand bed, I am tossing the idea of creating another DSB
but I had a bad experience with disturbing one once. So I am a lil skittish.
I plan to have SPS
in the upper left and center, LPS
on the right side (current/light/aggression requirements dependant), some polyps in the lower left, and plenty of growth room between all. I also want to have Tridacnid clams on the lower center/left which is why I was considering a DSB
to get them closer to my twin 175 MH
with 36watt PCs which I think most would consider marginal for them in a 24" tank. I figured with placement of the fixtures and adding in the sand and shell the mantle would be about 27" from the bulb, 21" of that being water, I am not super happy with that figure.
