How does this product compare with Eheim Biological Filter Medium?

It's comparable. Eheim media is definitely better, but it's also much more expensive. If you're using this media to fill up a canister filter and need a lot, get it. The difference won't be incredible. However, if you're trying to maximize the performance of a hang on back filter, or a canister filter, go with eheim and don't look back.

These bio media can be used in any filter than media can be added to. I use it in my canister filter along with bio balls. If you have three trays, it should be in the middle tray, above sponges/cotton, and below charcoal above. If you have only two trays, place above thye entry tray with sponges and then place charcoal on top. For a reactor and a canister filter, if the reactor is after the canister filter, you could put all the matrix bio in the canister and then use charcoal in the reactor. In variation will work as long as the water flow is: outflow of tank and enter the canister with mechanical (sponges/cotton) first in the the flow, then biological (bio balls or matrix or both) second in the water flow and chemical (charcoal, etc) the last in the water flow. This is the recommend order and ensures the chemical is last. Hope this helps and I can answer more, just let me know. Bill

This is prefilter, its primary purpose is not bio filtration. So it should be used in the first basket, before mechanical filtration. Most people seem to think this is for bio. If you want a media for bio, you should get biomax as it is much more porous than this.

I am about to purchase this but another customer has carefully opened the filter media holder and replaced the active carbon and filter floss with similar filter media used for fish since this is a basic filter. We already have such materials since we do own a 50gal fish tank. So you can go to the pet store and buy what you need rather than buying a brand new filter every month.

It replaces your carbon filter. It sucks up nitrogen-containing organic compounds, but won't touch metal ions, phosphates, or chloride. You will still need a bio-matrix medium, and will still need to use Prime.

I think their is enough biological included, I squeezed all that came with it into bottem two trays and then filled to top tray with Matrix. This worked but I found that 'low flow' warning come on. After a month I reduced the amount in all trays and found the flow rate had been resolved. Great filter so far the only think that is not working is the flow rate chart. I just wish it gave real flow volumes rather than percentages.

I would suggest checking the recommendations for the particular Eheim filter you are running because it should provide this information. That being said, the product in the picture is what came with my Eheim filter and I bought another box to have on hand when I need to change it out. I checked the box I have on hand and it looks like you can also use this product with the larger ceramic type media they sell. If your filter contains 2 baskets you could fill one with this and the other with the larger media. I hope that helps!

For a res tank, in the bottom basket i used Fluval bio max media, and in the second basket use pre-filter media. For the top basket, the best results i found were with 2 activated carbon bags. This combination will have your water crystal clear and odorless

Read my review on the Winix -- I'd pass on that one if I were you. I am not a big HEPA filter fan -- they are EXPENSIVE to replace and once nasty bugs get trapped, well, they can reinfect you. I'd look for something with electrostatic plates you can clean at no added costs.

Foam first because you don't want debris collecting in your biomax. This filter is pretty small, so I' m not sure you can fit enough biomax to make a good enough colony of bacteria. Better off letting you substrate colonize and just use foam and carbon in the filter.

I know you asked this months ago but I think all the answers given were incorrect and it is an important question. The product description lists aesthetics, chemicals, dissolved solids and radiological contaminants not biological contaminants. If you look at the Seychelle website, they describe their filters. The advanced filter removes bacteria and viruses but this one is meant to be used with potable water. They now have a combination advanced/radiological that they call "extreme" which covers everything. I apologize to Seychelle if I am incorrect, but if you read the product description carefully they do not say that this filter removes biological contaminants. Seychelle has the only filter I"m aware of that covers radiological. I'm about to order this and will use it with water purification tablets if I'm drinking non potable water.

I have a Marineland Bio-Wheel filter on my 20 gal tank and I use Algone all the time. Works great.

I have no idea, we don't use it. We prefer to use water that has already been filtered. This filter looks like it create a sanctuary for bacteria and bio-film and we also didn't want to have to purchase more replacement filters for this gadget. We've had our Krups for about a year and are very happy with it. We had a Krups before this one, so we're happy with the brand and designs. BTW, it's pretty noisy when it cranks up at 5 am in a quiet house!

I think seachem matrix is a good product. However I prefer Eheim substrate pro. Yes it is expensive but it lasts forever and does not break down like some other bio-media products and fall apart. I have friends that used the seachem matrix and they say they like it but for me I will stick with what I know works.

I'm sorry Ethan but I do not know the other model, so I can't compare. This model has been excellent for my astma, I use it in my office. The is another purifier brand, IQAir, http://www.iqair.com/, that I think is better, although more expensive, that I use at home.

Thank you for contacting AquaRain Support. Water conditions can be of great concern, especially when traveling to developing countries and the AquaRain has been designed specifically for this reason. Since bacteria vary greatly in size, porosity alone will not define the efficacy of a filters performance. The internal pore structure has a great deal of influence on ceramic filter performance. Testing with live organisms is the best determinate of performance. Our filters have been tested using the EPA protocols in a unique way. Our ceramic test articles were abraded down to 10% below their measured end-of-life and exposed to contaminated water before being sent in to the laboratory for testing. This was done to confirm that our ceramic filters were fully effective and safe to use until they reach their measurable end-of-life. Normal testing protocols only use brand-new, hand selected articles for testing and are therefore unreliable where the water quality is of concern. We went further and tested our filters with Brevundimonas diminuta, a very small bacteria used for testing in the health industry. We met EPA purifier standards even when using this much smaller test organism. Because of our real world testing results with this live organism, we realistically rate our ceramic pore size at .2 micron absolute. We have a great deal of information on our website especially, under the "testing" tab. There you will find a downloadable PDF Testing Summary Sheet for our ceramics. I hope this has answered your questions, please write again or contact us directly should you have any further questions. Kind Regards, AquaRain, Inc.

I've used the eheim for over a year now. It's simply the best filter I've ever used. A hang on back filter isn't even in the same league. Super quite and works great. BUY IT!!!
