Emperor Power Filters

Pros: Excellent water quality and stability. Fairly Quiet, Easy to Clean
Cons: Cost of filers could be cheaper

I have been running the Emperor 400 bio-wheel filtration system in my 58 gallon marine show aquarium for a little over two years now. I am also running a smaller version in my 35 gallon tank, but that has only been for the past six months.

...

Pros: Efficient, quiet, easy to maintain.
Cons: Can't think of even one.

WOW!! Have filters come a long way in 20 years!! I have recently re-entered our great hobby to find "the nitrogen cycle", and what must have been the reason I lost so many fish years ago. The power filters of the early 1980's were primitive by ...

Pros: It really works.
Cons: A bit noisy.

I must say, I have learned a lot about aquarium power filters in the past year. I can also say without any reservation, this filter makes a huge difference to our fish tank. The results, are shall we say, clear. I have tried two other brands, the first ...

Pros: Durable, Reliable, Powerful, All-Around Great Filter
Cons: Can be noisy with biowheel, large and wide,expensive media if use it.

The Emperor 400 is one of the best filters on the market and is possibly (some argue the Aquaclear 500) the best bang-for-buck filter on the market.

The Emperor 400, as it name implies, pushes 400 gph through the filter. A good number to use...

Pros: Excellent filtration, Ease of use
Cons: Pricey

Recently my husband and I were faced with a problem concerning our new 60 gallon glass tank. We raise guppies, platties and neons and the tank was not clearing up with the two filters we were using. Upon the advise of our fish store we purchased an...

Pros: Excellent power head. Dual filter/media/power wheel. Servicable.
Cons: Not for small tanks. Almost boolean flow control.

My 55 gallon tank, complete with two Oscars, four Tinfoil Barbs, and two Clown Loaches, started out with two of the high-end Top Fin power filters. They were great filters, but the level of nitrite in my tank was still out of control. Based on the...

Pros: Best filter on the market, unlike canisters there is no fear of flooding.
Cons: fairly expensive

I've been raising fish for over twenty years and few products actually do what they are suppose to. The Emperor filter comes in two sizes: the 280 and 400 model. This filter uses their "bio-wheel" technology taken from the larger "wet n...

Pros: The best biological filtration available in a power filter
Cons: Cartridges are a little spendy.

I raise African Cichlids. Inherent in this task are two facts. You must maintain relatively high stocking levels in order to "keep the peace" and these fish love to dig. These two facts place a heavy demand on a filtration system. My advice is this:...

Pros: Excellent Filtration, Easy Maintenance
Cons: Replacement Cartridges Expensive

First off let me say that I have been using Emperor filters for 7 years. I have many tanks ranging from 10-100 gallons. I house many species of African Cichlids. As anyone that keeps these fish knows, they are very messy. I currently use both the 280...

Pros: Does EVERYTHING, easy to use, great combination of filter options
Cons: NONE

I have been in the hobby for many years and have used all sorts of filters including aquaclears, magnums, penguins and a host of others. I recently setup three aquariums at work and was using several different filters on them. I had to replace a few a ...

Pros: good cleaning power easy to use quiet
Cons: replacement cartridges bit pricey

We have 7 fish tanks in our home and have 4 with Emperor Power filters. Since we have discovered the cleaning power of the Emperor it is our filter of choice. We have both salt water and fresh water tanks that have filters with bio-wheels and not. The ...

Pros: A great power filter. Easy to maintain and use.
Cons: Flow adjustment allows the pump to run dry.

I use the Emperor 400 on both of my 80 gallon salt water aquariums.

These filters are made by Marine Land and use the Emperor filter cartridges as well as bio wheels. The cartridges contain the physical and chemical media while the bio...

Pros: Easy to use, Easy up keep, Quiet
Cons: Lots of pieces to clean.....

I have a Emperor 280 on a 30 gallon tank and I love it. I have had it running for over three years now and really no problems to speak of. Keep this filter up and working well is really painless. I clean it real well about once every three months and...

Pros: Multiple options for optimum filtration
Cons: NONE

I chose the Emperor 400 filter because of the positive comments I heard about it everywhere I looked. A friend recommended it, as did multiple pet shops. I located the item online to purchase and it was listed as a Customer Favorite. I have found...

Pros: Great filtration, easy to maintain
Cons: Sometimes hard to get started again after shutting off

I have owned the Emperor 400 filtration system for about 3 years now. I think it does a wonderful job keeping my tank clean (55 gallons). I now have 4 goldfish and the water remains clear and clean. There are 4 slots for cartridges and you have the...
