setting up a sump

[trouble]

thanks for your input guys and the warm welcome its nice to get onto a forum where information is shared instead of coveted, been on some in the past where if you havent been doing it for a while then then you are considered unworthy to get involved in the conversation. my power heads are koralia 1& 3 are they not considered a high flow type?if not than what would be a good make to look at. as of yet i am unfamiliar with a good portion of the available products.
