The upper corner of my refugium seam started to come apart this weekend and being the paranoid person that I am when it comes to leaking I would like to see if I can find a 20 gallon long tank so that I could turn it into a refugium. Would like to find a tank that is near new condition, if not I prob just wait til the petco $1/gallon sale, hopefully that should be soon with the holiday shopping season starting up here. Hopefully not too far from where I am, thanks.
