SO! I am using this: https://www.google.com/aclk?sa=l&ai...hUKEwj_nsunr46GAxV8FlkFHaoVCosQqygIiQs&adurl= with my 11.4 gallon cube tank, is it safe? its been up for 3 months but im scared that one day it will come down, im thinking of putting 2-4 long screws beneath the top panel for extra support, should I do that, or am I fine?
