Review on 🐠 Aqueon QuietFlow LED PRO Aquarium Power Filter 75: The Ultimate Filtering Solution for Your Aquarium by Pamela Bellancoutt

You have to be very careful with these filters. We have a 55 gallon tank that has gone through 3 or 4 of these filters (next size down) in the last two years. So far we have used two 50 gallon Aqueon filters at the same time. We have goldfish and we love to get ahead of the mess they wreak. Now we use 75 and 50. They will burn out if you drop the water too far and you will have to buy new ones. Even for a few moments when we weren't sucking water, they burned. You must, must, must turn off the filter BEFORE you start the water change. Once the tank is full again, reconnect the filter. Help him by pouring some water into the filter canister that may have leaked. They are much more sensitive than other brands of filters, but we keep coming back to them as we place the tank in the bottleneck. They are flat between the tank and the wall.
