What is the quietist in-sump pump that will still push 1200gph or 800-900gph at a 4 foot head. I have *#$# Rios now and the pump great but loud as heck. I want stealth pumps! I don’t have room for a huge pump though or an outside of tank pump. I plan to buy two pumps to replace my Rio HF17 and my Rio 2100 any Ideas would be great.
