Ok so i have a 54 gallon corner tank at this point and am planing to upgrade to a 150 gallon fowler. What i was wondering is i would like to sell my 54 gallon to earn money for the tank i plan on getting. But i want the live rock for my new tank and i would like my live sand (if that is okay not sure). But how do i keep thoughs alive until i get the tank fully setup which will be months. Also i was wondering what do you think would be a reasnable price for my 54 gallon tank. It is not reef ready i use a fluval 405 and a cpr backpack I would be selling tank stand fluval 405 filter and cpr backpack. What should i ask for it.
