I'm planning my build and need pump suggestions that'll give me around 1k gph at 5' head. It'll need to be located in the stand, so noise will be of paramount concern. My secondary concern is that of heat transfer, as I'd like to keep as much pump generated heat out of the water as possible. I don't want to say that price isn't an issue, but I will shell out the cash for the best if te value is there. What's everyone's thoughts?
