I just realized that my 150 gallon tank is higher on one side than the other, by the water level it looks like between a 1/4 or 1/8 inch difference, no biggy, but I was wondering would there be anyway to level it without draining the tank. Should I leave it be or should I do something to level it. I've had it up for a few months now and just realized (I usually dont fill it up to the top but decided to fill it to the border and realized it wasnt as high on the other side)
