Rated 1 out of 5 by from just up and quits working in just over a year to year and half, i have had to replace this unit 3 times. Each time it is the same problem, it stops sucking up the water into the unit. The only reason, i bought the same unit was becuase of all the supplies i have won't fit anything else. Im lucky if i get a couple months maybe 6 at best before it dies and i have to get a new one. This can't be normal, but the same issue on all 3 is ridiculous.

Rated 5 out of 5 by from Might work forever I've run one 400 steadily for 20 years before replacing it with another. I've never had any problems other than impeller wear. Now using four media holders And four bags of resins, etc., for 8 different media positions. There's space before and behind each side of media holders for the extra bags or packaged media. For me, results have long been no detectable waste chemicals in my 50 gallon tank.

Rated 5 out of 5 by from ALL you need, a wise investment I have had four Emperor filters and three LED lights on five different aquariums. I am currently running two emperor 400's on the back of my 75 gallon Marine land tank with two marine land heaters .They tend to make you lazy because they are so easy to change the filter material even when they are operating!!Up until recently I only had one problem and it was taken care of. The last LED light to fail was refused after I had it only 6 mos, but then PetSmart came through for me on their own took care of it.

Rated 3 out of 5 by from Water flow I have two filters on a 45 gal. aquarium the pingeuin 200 and the Emperor 400. why is the water flow on the smaller 200 much higher than the larger 400. Is the Emperor just a larger filter with the same motor as the smaller one. I get more ripple on the surface from the small 200 filter. why?

Rated 5 out of 5 by from Good filter! Had mine for about a year and works great. It's easy to use and quiet. Thankful it came with a very long intake so that it can be custom trimmed to fit a large tank.

Rated 1 out of 5 by from Two New One Way Too Noisey I have one existing Emperor 400 that is awesome. I decided to add a second to my 75g tank. Bought one a week ago and the filter made horrible rattling noises. Checked impeller and all other parts and all was good. Decided that it must be defective, so I returned it to Petsmart for a new one. Installed new one today with the same issue. Called Marineland and we checked the impeller again and could not eliminate the rattling (castanet) sound. Tech support offered to send me another one ( which was great). However, I would tend to doubt that two brand new ones had the same issue. So I am not confident that the 3rd new one will solve the issue. Fingers crossed for when the new one comes in, but I would love to hear some reasons as to why this is happening when I have had one for years with no issues?????

Rated 5 out of 5 by from Excellent filter This filter has been excellent for over 5 years, have recently run into an issue with the bio wherl spray bars not spraying. It started with spray bars barely spraying,  so I disassembled the unit did a thorough cleaning, and when I reassembled the unit the bars sprayed for about 2 seconds and will not spray again.  I have had this filter about 5 years and no issues until now. No cracks, o rings are still good. Is it possible I might need a new impeller, there seems to be a lot of play in it? And the cover is on the bottom that keeps impeller in place.
