Strengthening the floor, if it is a fish tank with a straight bottom, the problem is not big, just be careful not to let the water pass between the bottom of the cabinet and the floor. The reinforced floor has enough compressive strength, but it is afraid of moisture. If there are earthworms or geothermal energy under the reinforced floor, it is recommended not to put them directly, because the tank is too heavy and the floor is slightly thick or low, which is an unavoidable problem for the place and a hidden danger for the tank. If there is an earthworm floor, it is suggested to remove part of the floor from the area where the cylinder is placed and let the cylinder land directly. It's safer this way
