My LFS is having a sale on aquariums. Im going to be doing an all SPS tank. Ive been looking at the 150 DD which is 36"x36" and the 200 thats 48"x36". I had a 180 for a while and was going to get a new one and get it pre-drilled but now Im thinking about going with the double deep one. If you had to pick which one would you go with, 150 DD,180 standard or 200 DD? My biggest thing with the DD one is flow, but I do have 2 MP60's. Im planning on ordering it today but wanted some input! Thanks!
