I purchased this filter to take care of my 125 gal. tank. When I pulled it out of the box, it was so very HEAVY. I could only imagine what it would have been like with water in it, and lifting it from under the tank, out of the cabinet. I did return it and got the next size down. Even then my husband had to help me carry it to the kitchen sink. Atheon has super great products with design of ease in mind. I love the 300 I bought, so I know the 400 would be just as good.

I keep it on a 55 gallon with two AquaClear 110s, no leaking in a month so far, strong pump & very quiet. I just purchased my second one. Update: 01/2020 I have 3 of these for now on my 55 gallon tanks. Quiet, powerful, long lasting so far. I use that hang on basket thing & add polyester filling to polish the water, I use a pre-filter on the intake & open the canisters every 4 months to clean them. Love this Canister filter.

Easy to set up, no leaks, quite, and moves a lot of water. My 135 gallon tank is staying nice and clear.

This thing is a beast, I love how you can change up the filter media to whatever you want. I changed it the carbon in one level to purigen. Never had more clear water.

No cons, only positive I just hope it works for a long time.
