When it comes to pumps, I think the main difference in external and
submersible pumps comes in what size is the pond. For small ponds, the
submersible pumps are best because you can get pumps with small flow rates,
but for large ponds, any of the submersible pumps that have high flow rates
also have large electric demand.

Hello all!

I am really and truly just starting out, as in no hole as been dug, but
the
area where the pond is going has been roughly surveyed. Last spring i
built
a small 100 gallon indoor pond, but i did it very quickly with out doing
much research. this time i want to do it right, and i'm trying to figure
out
how much money its all going to cost me so i can make a budget. Since i
don't have any sort of hole dug, i can only go by my theoretical
dimensions
to guess the volume. My concern right now is pumps (which is better
submersible or not, and how much its going to cost). and as you may have
noticed i'm starting to ramble so i'll cut it short. My questions are,
what's the best way to approximate volume (using some online calculators
i've gotten numbers ranging from 1,500 to 11,000 gallons)? and would
anyone
be willing to provide me with the pros and cons between the
submersible/non-submersible pumps, or at least point me in the direction
of
finding such information? thank you in advance!
