just got a 250 gallon acrylic tank for my jardini. planning to put it in my basement but im worry if i need to reinforce the floor. my basement floor is raised. will it be able to hold this tank full of water? tank will be sitting in the corner of two main walls. plus im planning to order 2 300w heater plus the 200w i already have, will this be enough to heat the tank? sorry this is my first big tank.
