henward Posted January 30, 2011 Report Share Posted January 30, 2011 http://www.eheim.asia/prod_e_media_setup.html here, they have course media, course foam, bio media THEN filter woold doesnt the media get clogged up? i have my fine wool before any bio media. also they have that wet and dry one. does anyone use that? it doesnt have any mechamical filtration. how does that work, doesnt the media get clogged quickly./ Quote Link to comment Share on other sites More sharing options...
henward Posted January 30, 2011 Author Report Share Posted January 30, 2011 never owned eheims before. but the profesional series, the water frmo tank goes from top, then the impeller sucks it from the bottom tot he tank. so in theory, the dirty water should first meet course media or foam. anyone with eheims with feedback?

kiwiplymouth Posted January 30, 2011 Report Share Posted January 30, 2011 All of my aqua one Cf's and sunsun work the same way. I.E. water flows from the bottom to the top of the filter Quote Link to comment Share on other sites More sharing options...
ryanjury Posted January 30, 2011 Report Share Posted January 30, 2011 Yeah mine are the same it makes more sense having the coarse and fine media before the biomedia but seems to work well with the fine afterwards. Quote Link to comment Share on other sites More sharing options...
blueether Posted January 30, 2011 Report Share Posted January 30, 2011 My cf1200 is setup per the instructions: In & Out \\PumpHead// 1 ||Wool 1 ||FineFoam 2 ||CoarseFoam 2 ||Noodles 3 ||CoarseFoam 3 ||BioBalls EmptySpace But I feel that there is a lot of wasted space and was also wondering how others have their filters setup. I was thinking of doing something like: In & Out \\PumpHead// 1 ||Wool 1 ||FineFoam 2 ||Noodles 2 ||Noodles 3 ||Noodles 3 ||CoarseFoam BioBalls (in bottom) or In & Out \\PumpHead// 1 ||Wool 1 ||FineFoam 2 ||Noodles 2 ||Noodles 3 ||Noodles 3 ||FineFoam 3 ||CoarseFoam BioBalls (in bottom) Quote Link to comment Share on other sites More sharing options...
henward Posted January 30, 2011 Author Report Share Posted January 30, 2011 i have all my foam before any bio media Quote Link to comment Share on other sites More sharing options...

SamH Posted January 30, 2011 Report Share Posted January 30, 2011 I've always found that first mechanical media in order from coarse to finest followed by bio media works best. So coarse sponge, filter wool and then bio noodles/rings/balls. Just stops the bio media from getting clogged up too fast. HTH. Quote Link to comment Share on other sites More sharing options...
Rabbit Posted January 31, 2011 Report Share Posted January 31, 2011 FX5 filters top down Quote Link to comment Share on other sites More sharing options...
henward Posted January 31, 2011 Author Report Share Posted January 31, 2011 yeah iput the filterwoodl on top basket and fill two bottom ones with bio media. I find that works well and doesnt clog the bio media as fast or much at all. qwhy would eheim recommend letting dirty water pass through bio media?

suphew Posted January 31, 2011 Report Share Posted January 31, 2011 Have you guys actually looked at the link? The first product used is Eheim Mech which disburses the water. It doesn't say it but I'd assume it also houses heterotrophic bacteria which is the one that breaks solid waste down into Ammonia. In most of the filters this is then followed by mechanical sponges and then the biological media. Quote Link to comment Share on other sites More sharing options...
henward Posted January 31, 2011 Author Report Share Posted January 31, 2011 eheim prof 2, 3 and 3e and classic. the mech is the last one before it goes out. i am seeing that the bio media get flow first before course and mech media. unless im wrong with my flow. i dont reall use eheim. im jsut curious as this is more for curiosity than actual practical use for me.

Eheims, flow direction is from the bottom up. If you look at the classic's in particular the input fed is on the bottom and the motor on the top.

suphew Posted February 3, 2011 Report Share Posted February 3, 2011 Heterotrophic bacteria has a bad side Only happen's in anaerobic conditions which is very unlikely in filter with all that oxygenated water flow. But this is the reason why filters should be cleaned when there is a power outage. For those that are interested here is some easy to understand reading on Heterotrphic bacteria. http://www.bioconlabs.com/autoheterobac.html Quote Link to comment Share on other sites More sharing options...
livingart Posted February 3, 2011 Report Share Posted February 3, 2011 only a possible problem if your water dissolved oxygen levels are very low Quote Link to comment Share on other sites More sharing options...
henward Posted February 3, 2011 Author Report Share Posted February 3, 2011 oh ok the eheim prof series puts the water stright from the top and pump sucks it from the bottom, so water flow is top to bottom and up again, does that make sense?

Adrienne Posted February 4, 2011 Report Share Posted February 4, 2011 so with the fx5 should the coarser media be at the top? Quote Link to comment Share on other sites More sharing options...

Adrienne Posted February 4, 2011 Report Share Posted February 4, 2011 hmmm... maybe thats why my fx5 hasn't done as well as I thought it would. :oops: Quote Link to comment Share on other sites More sharing options...
henward Posted February 4, 2011 Author Report Share Posted February 4, 2011 my have fine filterwoodl on top baster and bio media at two bottom basket, i dont bother with course bio media, i go straight to filterwool Quote Link to comment Share on other sites More sharing options...
suphew Posted February 5, 2011 Report Share Posted February 5, 2011 Yep No FX5's work from the outside to the inside. The dirty water goes round the outside of the bucket, through the foam to get to the biomedia in the middle of the bucket. This is a great system because you get a huge mechanical filter area so it need cleaning far less often. Quote Link to comment Share on other sites More sharing options...
GZ_Loach Posted February 7, 2011 Report Share Posted February 7, 2011 Eheim has better bio effeciency, it has been proven in a lab test compared to the fx5's, what they found was that the fx5's were a little bit better at removing suspended particles from the water due to the large number of foam blocks. And depending on what your keeping in the tank I would prefer bio filtration over mechanical as most filters these day come with more than enough mechanical filtration and not enough bio filtration, I guess it all comes to down the the fish and how much waste their making. Also the fx5 hasn't got anywhere near the flow rate that it claims to have as they test the flow of the motor by itself, not the whole system with media etc. There was a link here somewhere where the thread was posted on monster fish keepers.com. But in relation to the subject, did the fx5 have instructions as to how the media should be arranged inside the filter? I've always thought its better to have the water travel throught course media 1st and then bio media through to fine spodge (I don't like using wool) Quote Link to comment Share on other sites More sharing options...

The dirty water goes round the outside of the bucket, through the foam to get to the biomedia in the middle of the bucket. This is a great system because you get a huge mechanical filter area so it need cleaning far less often. Read you manual Quote direct from page 13 of the manual: 1. Filtration always begins with a mechanical stage of waste particle removal as water is drawn through the foam that lines the perimeter of each basket. It continues as water is pumped "down" through the "media" in the three baskets. 2. Bottom media Basket, This basket receives the purest water stream, making it the proper place for dedicated biological media. As for Eheim having a better bio efficiency, this would depend on the media used, as the FX5 doesn't come with it's own media i would like to know what they used as a substitute. Although the filter states the pump has a flow rate of 3500l/h which is true for the pump, page 4 of the manual also states that the filters circulation is only 2,130l/h so the fact they could prove the output wrong was never that at all they simply didn't read there manual.

Why do I need to read the manual, isn't this what I said? The water starts outside the mechanical filter media, on the outside of the bucket, goes through the mechanical media to the inside (biological media) of the bucket?
