The tank is a standard 180g, started with 50 at no bigger than 2", no idea how many I have left now, maybe 20ish?? very difficult to count them.
filtration is a 50g sump shared between the cariba tank, the diamond rhom tank and the curupira tank, running auto drip at about 1-2g/hr.
have two HK8 in the 180g (2x 3250gph) plus whatever flow I have from the return pump.
