@Kayen: yes, the maintenance is fairly little, tho its more than i'd like haha. it would be much less if there wer no shrimp.
@Squared: Water changes on this are 95% twice a week. The funny thing is about my reef, its the frag tank, but my main reef is actually smaller by 7 gallons :P The main reef is a 3 gal pico. You can find it on nano reef forums.
@Pinoy: Right now I am back to more than 20 shrimp, most are the smaller youngest generation, though a fair amount of the juveniles still remain (I have to catch those out of there soon) No water circulation, during water changes it gets lots of mixing but otherwise the shrimp can create their own currents for respiration.
