Emperor 400


daryl

Emperor 400 is perhaps the top of the line in Emperors. It pumps 400 gph. THere are two baskets that hold biomedia - mine are packed with ceramic cylinadars but you can use sintered glass, lava rock, small bioballs or other creative things. There are two cartridges that do the mechanical filtration. Two biowheels finish it off.

The biowheels are driven by spray bars, so they do not rely on speed of filtration. The cartridges can be rinsed and shaken at each change. I think mine only need replacing about once every 6 months. Because there are two of them, you can do one at a time and never lose any cycle.

My 400 does not selfprime with out a bit of grinding and work - something I am loath to let it do. In the times of power outages, though, it has self primed. The three I have have never failed me in any way.

They can be found relatively cheaply - particularly on line or during a sale.

The 400 is rather wide - it takes up the majority of the back of at 20-30 gallon tank.

I really like the Emperors. They are my favorite of all filters.

Since Daryl gave you all the info you need I can only add that I too like mine very much. I have had one for almost 6 mo. I upgraded from a Whisper and wow what an improvement!!

I've only had both mine for a month now, but I can truly say I'm impressed with the ease which they have cycled in. I've used a bit of cycle according to the directions, and like Daryl, I used bio glass in the extra media cartridge with the exception of one that I put extra charcoal in. Eventually I will add chicken grit (aka oyster shell) to that instead of!

None of my Emperors have ever been noisy - in fact they have been extremely quiet.

EXCEPT, just this last week I cleaned the 280's and now they are noisy. Go figure. It has been years without a hitch or complaint and now!!!! :blink:

I am thinking that somehow I got something put in crookedly or not quite correctly in some fashion. I am going to take them all apart again this coming weekend and see if reassembly will quiet it down.

I am almost leary of cleaning the 400s! :blink::lol:

My 400 has been very quiet too. No problems here. Of course now when it is time to clean it it makes "mice" or sucking noises but you have to really be right next to it to hear it.

My 400 is also very quiet. If you listen carefully you can hear the water as it hits the bio-wheels or maybe it's the sound of the wheels turning but thats about it. I've cleaned mine and have to say it was easy .. and putting it back together went without a hitch AND it's still quiet. It is big ... however, it does a very good job.

I have nothing bad to say about the emporors. But, I will share with you what i have read:

The gph of the pump may be at 400 gph but isn't the spraybar/s ran by the same pump? If i'm not mistaken, I think I remember someone doing an experiment with the emporor 400 and it didn't pump anywhere near 400 gph. I cannot, for the life of me, think of how many gph they discovered their emporor actually pumped. Now, I don,t know how controlled this experiment was or what but it definitely deserves some thought if one were to be trying for the "ten times filtration per hour" rule of thumb.

Just a thought....... ;)

That makes a lot of sense! That may be exactly the reason why I need over 15X when I am using all Emperors to achieve the level of filtration I want!

Hi Carol!

Judging from the size of the spraybar hoses, I'd venture to say you could be losing up to 100gph. Maybe more like 70 though. ;)

Uhhh, that sucks. Now I'mma have to get another filter to put on my 125 since I was just gonna use 3 Emps. Hmmm... those canister filters that have a heating option are pretty cool.......... :)

The filters with a heater built in do sound really cool. However, as with many things that are combinations, the "life" of the components do not necessarily match. As with TVs and VCR combos, the VCR dies many years before the TV part does. And then you have to dump them both!

Two people I know have filters with the built in heaters. Both of them have experienced heater failure within 2 years of use - yet the filter is functioning fine. They have stated that they would not purchase that option again. They would rather have separate components that could be replaced separately as the need arises.

Just a thought.........
