Picked up a submersible pump today at a local tool shop called harbor freight for $9.97. Its small but they had big ones too for cheap. I might put it in my 35 Gallon SW tank for a little more movement dunno yet. I have it in a bucket now with a piece of my LR that has that razor hair algae stuff on it. Gonna leave it there w/o any light til its dead hopefully and it still remain LR.
