Rated 5 out of 5 by from Solid filter I have been using this filter for years now. Unfortunately it has become very loud still works perfectly however the noise is extremely annoying. I would like to buy another one to replace the current noise box but I can't seem to find an emperor 280 anywhere for sale. Other than having noise after years of use I still want another one because there isn't another hang on power filter that works as well as this one great overall design.

Rated 5 out of 5 by from still think its the best filter for the money i read a lot of the reviews about these filter and its unfortunate that some people have issues with it. i have used mainland products for my aquariums through the 30 plus years I have had aquariums and the emperor and penguin as well as the magnums and have had great success with all of them. i have 4 emperors running split between two 65 gallon aquariums they are quiet both are in my bedroom all i hear is the water moving. These filters are easy to maintain as well. i utilize the reusable media containers

Rated 4 out of 5 by from great filter I'm running these filters on 7 tanks. To make these filters perfect they need to be quiter and have rinseable filters that don't plug up so fast.

Rated 1 out of 5 by from Horrible! I have had this filter now for three weeks. I have 150 gallon tank with two turtles. It worked great the first week. Then it stopped sucking up water. I have cleaned the entire filter checked the intake valve and propeller and there is absolutely nothing wrong with it. I have no idea why it's not working. I still have to manually clean my turtle tank out every week to keep it clean. Was not worth the money I spent. Returning it today.

Rated 5 out of 5 by from Marineland Emporer 280 replacement I'm so sorry on my response to your email, I was on my phone and I accidently slid my thumb over the report button and no...and it wouldn't let me change it?Why did Marineland quit making the 280 model??? What replacement did they make for a 20 to 30 gallon tank? I really love the dual action with the spray bar. I know the penguin filters are there but I really like the spray bar action. All said and done...they are the best power filter on the market! And I have tried a lot over the years.

the spray bar is not working on my 400. just cleaned it and hooked it up. no water is getting to the bars. the water is flowing very good. any suggestions

Asked by: hollywood22
This means your flow manifold cover was not put back in place. You probably left it out. It is a "tear drop" shaped piece about 2" in length that snaps over the impeller onto the bottom of the flow manifold housing itself.BREX

I have one and it will not work anymore

Asked by: Tom Gosorn
We are sorry to hear this Tom! If you haven't already done so, remove the intake tube, and the flow manifold housing. Using distilled white vinegar, thoroughly clean the intake tube, impeller, and bottom of the filter box. Take a q tip or soak the corner of a paper towel with vinegar, and clean out the well of the motor in the center of the bottom of the filter box. You may have some mineral or other build up preventing the impeller from turning properly. Your unit has a 5 year warranty, so if you are unable to resolve this issue, simply give us a call.BREX

Can I use emperor 400 w/ a sand bed tank? Will it clog it and cause problems?

Asked by: nora
Excellent question! Sand will clog ANY filter if precautions are not taken. You can use the Emperor 400 with sand, but be sure to not allow the intake tube to be any lower than 1/2 way down in the water, and fill the bottom and mid-level strainers with some filter floss. There are also strainer pre-filters on the market that you can slip over them as well. BREX

Is it safe to use an extension cord to plug in the emporer 400? From where my tank sits the drip line is just a little shorter than I'd like, but it's the only spot in the house where a 60 gallon tank will fit.

Asked by: Kiti
We appreciate your contacting us regarding this potential issue! No, and extension cord would not be safe. We recommend a powerstrip for all of your aquarium products, that is UL approved for aquariums, and has surge protection. BREX

is there just one size bio wheel for these filters? I know I use an "E" size filter cartridge.can u please help me figure the right one also what is the best schedule for changing the wheels? thank you for your timeBest regards

Asked by: Toddsan2002
Thank you for your support of Marineland products! Yes, there is only one size of bio wheels that fits this filter. The bio wheel should never be replaced unless it has become damaged, warped or lost. You would need this particular bio wheel: http://www.marineland.com/Products/aquarium-parts/Filtration-Products-and-Skimmers/Emperor-Parts/BIO-Wheel-Assemblies-for-Emperors.aspxBREX
