Emperor 400 Questions
Bio0Wheel Power Filter Emperor 400 Complete 3 stage filtration.
For up to 90 gallons filters 400 gallons per hour.
how does it work for you?
Id love to hear opinions.
I dont like the marineland cartrages because of the carbon and the price, but other options are available including a media basket which is what I use. Bio wheels are not the best for use with CO2 injection, and thats why I am looking to replace mine with a canister.
Well the Emperor 400 comes with two of the Actual Filters 2 media baskets that go infront of the filters and then two biowheels.
ive been thinking about Co2 injection. Is there any risks? like can to much kill my fish? is it difficult to set up?
Also i can find a variety of plants. my LPS only offers two types of plants and Petsmart offers the same ones.
Do you buy yours offline?
Well, I cant give any advice on how well the Emperor work with Co2, since I do not have Co2 in my tanks. I do have 3 Emperor 400s, and i really like them. The media baskets are great for adding extra carbon to remove meds. I buy generic media from DoctorFoster and Smith. Alot cheaper, and comes with a clamshell frame, so you can make your own media and save even more money. The filters have given me no troubles. Always start right up. Bio-wheels are always working properly. Have also used the bio-wheels to jump start a cycle on a new tank. Worked great!
bio-wheel is great idea but as it gets build up of gunk, it will stop turning. Needs jet spraying to remove the gunk or replace the wheel.
Wether it will handle 90 g, depends on amount and type of fish but would not recommend to use on 90 even 2 of them. Better off w/ 2 canister type.
I guess when someone said not w/ CO2 injection, I'm assuming CO2 loss due to action of bio-wheel thus purpose of inducing CO2 injection is waste of efforts.
well whats so great about the canister type? it seems to be twice almost 3 times more expensive and the GPH are alot lower? I understand the Co2 loss during the bio wheel action but
$234.99 for a
Up to 100 gallons
vrs a 55$ Emperor 400 which is up to 90 gallons 400 GPH - Hang on power head
Ill spend the money if it seriously runs laps around the Emperor. Please and thank you for the help :D
I use two emperor 400's on an 80 gal discus tank, Two emperor 400's on a 75 gal and one emperor 280 on a 29 gal tank. They are no trouble and actually are a bit overkill on the 80 and 75 gal. If you keep the return water entering the tank below the water line then surface agitation that could drive off some co2 would be minimal. You just wouldn't want the water fall affect . That means keeping the tank level at the same level as the trim around the top of your tank. The spray bars on the emperor are easy to clean with the brush provided and i have cleaned them with the filter running. The bio-wheels should never be cleaned. The impeller needs cleaned once every couple months or whenever the flow of water is slowed down and does not pickup after rinsing the filter cartridges in aquarium water that you take out at water changes and is easy to do. I put the blue filter cartridges in the back furthest away when standing in front of it and the grey media cartridges closest to the back glass and they are filled with ceramic beads for extra biological purposes. The blue filters catch the majority of the crap in this way and grey media containers don't clog up. Once every three or four months I rinse them out if needed again in old aquarium water. Never use tap water. Hope some of this helps.
A big benefit of the biowheels over other HoB designs is that the primary source of biological filtration, the bio-wheels, are the part of the filter you're not going to mess with. You can perform normal filter maintenance without the risk of disturbing the bacterial colonies. If you're going to get a HoB filter get a marineland bio-wheel one.
Canister filters are less work. The instrsuctions on mine, say to only clean out every 3 months. Most of the media inside can be washed off and reused. The biological section rinsed in tank water. After the initial cost, they are very inexpensive to maintain. Not to say you should get one. The Emperor is a fine filter. I have never had to replace a bio-wheel. My bio-wheels on my goldfish tank are the only ones I have ever had to clean. That was do to some algea growth from indirect sun light. They easly cleaned off in old tank water. The spray bars can get clogged over time, but easy to clean with the brushes you will get with your filter.
I find canister filters are way more trouble than Emperors. Canisters require a special effort to clean, where the Emperor filters have cartridges that are very easy to access at any time.
Additionally, if you were to go several months without cleaning the canister units, the buildup of detritus has the possibility of causing problems with your phosphate levels and carbonates that make up your buffer system. These are problems the marine hobbyist is very familiar with, paying very close attention to these ions. The same principles are at play in a FW tank.
Canister filter manufacturers often brag about the forced flow of water thru the filter pads. I laugh at theses statements, because the water is forced to flow thru the filter pads in a Hang on unit as well. The only exception is when you neglect the clean the pads. And the truth is you would be better to not have mechanical filtration at all than have mechanical filtration thru a filter pad clogged with detritus.
Moving on, not only are the Emperor units very efficient biological filters, they are exceptionally well designed. The placement of the blue filter pads to catch debris allows for the activated carbon chambers to remain unclogged. This high efficiency use of activated carban is very effective at keeping Nitrates low! The reason is that activated carbon absorbs organic acids that would have been processed by the biological filter. In the case of the Emperor, ALL WATER first flows thru the activated carbon chamber, effectively removing organic acids, before these acids have the chance to be broken down into Nitrate by the biowheels. Less organic waste entering the biofilter means less buildup of Nitrate.
It is really an incredible unit. I doubt there will be any advancement in the FW hobby for a long time that outperforms the effectiveness of this hang on. For the last decade every manufacturer has tried, but so far nobody has touched what Marineland has accomplished with the Emperor product line.
If you haven't noticed, I won't use anything other than Emperors on my FW systems. I have used them on dozens of setups and never experienced any degree of dissatisfaction.
