hi i currently have a 60 ltr tropical fish tank. Im going to be upgrading to a 125 ltr tank. Am i ok in using what water i have left in the old tank which is just under 50% and filling the rest up with treated dechlorinated water. Bare in mind the new tank will have a canister where my old tank has a hexagonal gravel filter. All i got is a sponge driven filter by the air pump i can transfer over. In the canister as its all dried out i was going to replace with new media. Im hoping other than daily water changes for a bit this should be it? Sorry im not a hardcore fish keeper so i dont really know much on the tank switching. Be gentle with me
