media level in a sand filter tank

[Poconos]

Only difference between a boat patch and a tank is the pressure. Just remember that even at a few PSI the forces trying to open up the tank are quite high. With the fiberglass webbing though you may stand a good chance. Got nothing to lose.
Good luck and keep up posted.

Thanks y'all. I hope to have the time tomorrow to be able to drain the tank and take a good look at it.

My only concern right now is that I will not be able to physically reach the bottom of the tank. I will analyze that situation when I break it down.
