I am absolutely amazed at this pumps power especially as quiet as it is! I have more than 60 outlets running and I see no evidence that it will not handle even more. You can literally stand right over it and barely hear a sound. I hooked it up to a 1/2" Schedule 40 PVC line I ran all the way around my 15'X12' room. From there I used the small valves in holes that I drilled into the PVC above the tanks and aquarium tubing ran down from there into the tanks sponge filters. Makes for a great system with plenty of power. I am really impressed and happy with this product!
