btw, guys, for specs on my 1ft. i DUN use skimmer at all. only small boyu powerhead to make the little wavy features and normal hang on filter. plus a pc fan, and temp stays at 26*C. im quite surprise with my little experiment coz most dudes says a skimmer is a must for all saltwater tanks. BTW, only gt 2 common clowns, 1 fire goby, 2 turbo snails and 1 blue leg hermit. mayb gonna add 1 more hermit and 1 snail. Will it b too overpoppulated?
