![]() Quote:
I was hoping to move the same amount of water with an MP40 on, say, 50 or 60 % instead of an MP10 on 100%, thus reducing the total noise output ![]() But, after listening to the ones I've been near to so far, I'd say the 40s are mucho louder than 10s, even at low speeds. The 40s tend to growl and grind, whereas the 10s only have a higher-pitched whine/whistle to them ... kinda like a street-vacuum-truck-kinda-noise in the distance I got some tips from Tang Daddy After a conversation with him, I changed the setting and may even try the 2 pumps I have on different panes of the tank So, today I will move them around, instead of the standard locations recommended by EcoTech, and we'll see what happens ![]() This may even lead me to buy a 3rd 10 ... who knows ![]() |
