Cycling for Tank Upgrade
I have a 25g live plant tank with two Marineland 225 canister filters, an Aquaripure nitrate filter made for a 60g tank and air stone. There are currently 2 goldfish that are about 6 inches long and one 4 inch long.
I am planning to upgrade to a 50g tank using all the same equipment and gravel. I will have to add some new gravel and plants because of the increase surface area of the tank floor.
Is it necessary to cycle the new tank before putting in the fish or can I transfer all their equipment, plants, gravel and an additional bacteria product?
