how much waterfall foam do i need ?

[mofal]

Hello guys,

my pond will be 13 x 13 f , 4 feet deep
waterfall height is 3 feet , width 4 feet

am planning also to use this foam for stabilising some rocks in the pond it self

the question is :

how many 12 oz cans of foam do i need to build my pond and waterfall ?

That is a hard call, depends on the size of your rocks, the number of them, i used one can to take care of one small waterfall.

Check ebay for some cheaper prices.
