Pre-form
I haven't been able to find any large (150g) pre-form ponds in this
area and would like something around 500g or larger. I've seen that

Lowes has a 270 gallon preformed pond, thats where we got ours. It was around
$300. They have one that is I think 300 gallons also, but it doesn't have
plant shelves. I don't know what the cost of it was.
