Just went from my 3 gallon Picotope to a 6 gallon nano-cube, I cant believe how many critters, LR, and coral that i crammed into that little 3g tank lol! I took my old stock 50/50 and mounted it in to the hood so now I have two lights. Sorry no pics I'll get some up soon, anyway i love the look of this new tank, but its missing one thing a fish or two, I think before I add any fish, id like to add a 15g-20g sump/refugium under my desk, anyone have a good link or some tips on how to go about this?
