Thanks everyone. By "bottom drain" I meant a siphon system that removes excess water from the bottom of the pond and not the top.I will be using a siphon system... Instead of worrying about all the formulas and calculation I read about Can I just go with 10 or 12 inch pipe and be done with it? I understand too small of pipe could be very bad but too big? Is it just because of the price of pipe? Or can you have too large of pipe. My only thoughts would be too large of pipe would make it that much harder to "start" the siphon effect. Thanks for any more advise.
