Letters, we get letters

Dear Pondlady,
I want to use heavy duty visqueen for my pond. It's cheap and I don't see why it wouldn't work.
I also need to know how many gallons I have so I know what pump to buy.

Pondlady sez: 

Use 45 mil butyl rubber liner. It is fish friendly and will last longer than 6
mil plastic. The visqueen will tear while you are putting the pond together. The rubber liner comes with a 10 year guarantee at the very least, usually 20.
Gallons of water are figured like this: length x width x depth x 7.5 gallons per
 cubic foot. The proper pump moves half the water every hour, so knowing how many gallons you have leads you to the right pump. Larger pumps than necessary are great because they push more water over the waterfall.
