cheaper substitute for pond armour?

[daninthesand]

Hi everyone.

I was on this forum about a month or so ago and came across a thread by a guy makig a plywood tank and lining it with a product that was made in Canada which is more of a flexible product that he mentioned could line a cardboard box and hold water. It was also potable. For the life of me I cannot seem to locate the thread and since I can't recal the name of the product, searching has proven futile.

Does anyone know what i am talking about that can direct me to that thread?

thanks a lot.

Yep, Zavlar liqiud rubber.

About $60 AU for 4 liters, enough to do a 6*2*2 tank.
