125 gallon reef
54 gallon fowlr
20 gallon as a safe home for my peterson's shrimp (he's spoiled!)
and a few QT tanks that I just took down, didn't count them.
125
120

50
5
150 rubbermaid tub
100 rubbermaid tub (both tubs will soon be part of central filtration for the 125, 120, 40B, and 22, along with a 50 gal frag tub)
