Moves a ton of water, but noisy By tvoydan on 1/3/2014
tvoydan wouldn't recommend this product to a friend
Both 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.
