Nice product By G$ on 3/6/14G$ would recommend this product to a friendVery quiet. The 2 head / controller combo a good deal. Simple to set up. Plug n play. They are big but until you spend more than twice as much it doesn't get smaller so you get what you pay for. Very satisfied
Moves a ton of water, but noisy By tvoydan on 1/4/14tvoydan wouldn't recommend this product to a friendBoth pumps (4000 and 3600) move a ton of water. Incredible! The 4000 alone would be enough for my 195ga. In combination they're just amazing.Unfortunately they make a steady hum while running and don't think I can live with the noise. The controller directions aren't the best, but after playing with it for a while, it was pretty easy to get working. There's no option to just run both pumps at the same time. You can only cycle form one pump to the other. This would have been a 5 star product if it had not been for the noise.
