I have a water fountain that is run from a huge water fall pump that used to be in our water garden. I have the pump sitting 1foot off the ground on a milk crate. It is sitting in about 3 fit of water right now..

What water depth should I have the fountain in and also is this aerating the pond at all? Or do I need to buy an aerator instead? The pond is 7/10ac and 16ft deep by the dam.
