I have a quarentine tank around 60 gallons, just the tank (I'm keeping the filter on it), it is an old lobster tank, as its not that high (I can get the measurements again, don't know where the tape measure is at the moment) I can trade you. You can drain it out the bottom, through that tube, I just have it blocked off with sink plugs for now.
Heres some pics, if you have any questions or are interested, just let me know
Thanks,
Unannon
