So I am looking to upgrade to a much larger aquarium but in order to accomplish installing the new tank I will have to move my current 75 gallon display. My in laws have a 300 gallon Rubbermaid that the grandkids used to swim in. I was planning on curing rocks anyways and was searching for a tub large enough to cure enough rocks for the new larger tank but figure I can maybe just use this to house all cristters and maybe also get some live rock cooking. Would it work if maybe I only lit a portion of the tub to keep coral happy and utilize the rest to cook some additional dry rock? Has anyone ever used one of these for a somewhat temporary all in one tank? Any advice or input?
