Yeah I was aware of the 9-10 times that I will need to drain and refill the tank. It kind of works out anyway cause I will be adding sand as well to the tank at the same time so I will be lowering the pH as well as siphoning out some of the dust kicked up by the sand.
Also, from all of the videos I have seen on youtube about making your own background, once the cement is "set" as you say in 24 hours, it is good to put in the tank.
