alright this is completely up in the air, but i'd like to put a basement pond in for my mom. she has a wide open basement that gets 0 use except for the washer and dryer. i'd like to build a cement pond that is 3x5x3 which on the conversion chart equal a little more than 330 gallons. i'm looking on lowes and thinking about getting a water pump for the filtration system i want to put in and should i get a pumps exactly what the pond is equal too or should i get a pump that would pump 4 times the recommended amount just like a regular fish tank. there isn't a big price difference between the pump sizes. my only fear is the pump being too powerful and shooting water out the top of the filter.
