Thanks Andrew, good info. I agree that it increases the surface for bacteria a lot. For bioload/algae reasons, I got rid of my goldfishies (except for a small kinda fancy one) and the two dozen mosquito fish and few minnows provide barely any bioload.
Yeah this was more towards koi and other high volume ponds but I would do it on any pond.
When I had my pond it was all local caught fish, and the goldfish my mom insisted on..... but it was amazing having baby sunfish, a native catfish frogs and the like from the area. Sad to say since we sold the house I will be willing to bet the pond is WAY overstocked, but it may be going fine, maybe I'll see if I can arrange with the current residents if I can go and see it, but that is unlikely. (only moved a mile away lol)

well usually in large ponds you only really change water if your liner breaks, we had it happen twice I remember because of tree roots.... so you will just have some much and decaying matter on the bottom which is probably really good for it, Haven't had a pond since I got back into the hobby because of how our house is and we have no fences and small kids next door, so right now a big pond would pose problems my parrents dont want to figure out.... (even if I can get a solution.
I really really love ponds, I hate not having one.
