I just spent about 12HOURS working on a 30GALLON TALL. I mudded it down, and planted it, then put a layer of sand on top about 1/4CM thick. I had set it on top of a board on top of a dresser cuz the dresser wasn't level. I had it set this way all year, and just redid the entire tank today, and just finished. when i finished i realized the front middle right of the board concaved. I can fit pennies into the gap, so I did for the extra support. Is my tank in danger?? Do you think it can hold for 10HOURS without breaking or leaking?? I have 2BROKEN legs, and did this all by myself. My legs have metal implants which allow me to walk, and i'm so exhausted, and in so much pain, I don't think i can continue any further. I need to rest, before I drain it, and level it back out the way it was. Will it hold long enough for me to sleep?? The gap is about 6 inches wide and there other even smaller gaps cuz the board is warped. but the big gap I filled with pennies which were hard to set in, but I put them in there for the extra support please help. I need to know if I'm gonna have to break it down again, cuz at this point I can barely move, and will need to take more percocet, and try and drain it. 8(
