not talking of water change.
water can be expensive especially using home water, count on how much you drain. (water bill)
either a new or old tank, test leak. no leak detected, fill away.
few days later, you look at bottom of the tank... the horror, water form at the rear of the tank.
to reseal the leak (or change to a new tank), must suck out the waters.
unless have plants to water them, suck them out and throw them away...
also no need cycle. (it the same water, still has healthy bacteria, no?)
you use 'something' to store used water?
