Im going to take ever thing from my 15 and some from my 60 gallon tank to a 36 gallon tank. I will put the 15 gallon tank to the 36. How would be the beast way of moving ever thing from the 15 to the 36? What about move a lot of water and add the rest of the water from my 60 gallon tank(like 20 gallons)? Would this work?
