im curious if there are any crabs or something that will sift through my sand that i can add to my QT tank with dead sand and rock. im worried about the buildup of nutrients/waste in the sand so do you have any ideas on how to take care of this problem. i talked to someone recently who had several feeder shrimps make it through hypo, so i was just curious. maybe something that is a brakish species? have you tried before and it not work? im considering getting a few $1 crabs and see what happens.
