mojano infest

[mossman604]

so i put my good rock from my 40 into my 75 and set it up, the 100 lbs of mojano infested rock i put in a rubbermaid container, after 3 day it really started to stink like dead body stink. so i moved it outside. it has been a week now i made up a 5g bucket to rinse the rock off and im making more since the water has formed a membrane over the surface and there are about 1000 mojanos on the bottom of the rubbermaid, im letting the rock sit in an empty bucket for a while till my new water is ready.

any comments, am i doing things that are bad¿
