Here is my month old 28G JBJ Nano w/150W 20k halides, auto top off, temperature controlled, box of awesome. I like it

Calcium addition via CaCl2, buffered by Kent superbuffer dKH. Trace elements, buffer and magnesium added by ATO. Feeding is H2OLife frozen rotifers, cyclops, and oyster milt about 2-3x a week. Currently skimmed by a very old BakBak 2R. Tank is experiencing mild diatom problems likely due to a combination of source water (RO only, no DI) and the fact that it is so young.
Future addition plans; several Acans and more SPS.
