what is the best way to transfer all my fish from a 60g to a 200g tank? my 60g tank has about 150lbs of live rock and 100lbs of live sand. tank's been running for about 3 yrs now and it use to be a reef but now it's a FOWLR. i would like to do the transfer in 1 day and i have seen other forumers do it before but i cant find the thread anymore. am thingking of putting all my stuff from the 60g to the 200g and fill the rest of the tank with new saltwater. will this work? would i have enough beneficial bacteria for the 200g? am also thingking of using a 25w uv sterilizer but am afraid that i'll affect the beneficial bacteria in the tank. am i algae free with a uv? all suggestions are welcome
