I know a lot of poeple use QT tanks, my question is after (cycleling)setting up and after useing this tank what then become of your tanks? meaning do you keep the water in it, heater,filter and power head running to keep it cycled or sould I just start all over and shut it completly down untill the next use? Or if i were just useing it as a holding tank for coral or other fish? I have since gottin a lionfish that a friend had gave me and I wanted to use this tank when Im doing major clean up or mantinace on my 55 gal for short periods of time, I dont really want to get stung by this lionfish :death: LOL, know what I mean Your help is much appericiated :D......
