      K1 Microbead reviews? Question on pump

      Hello,
      My husband and I are looking to add to our filtration. We were interested in the EA K1 Microbead filter 24". I cannot find any reviews on it. Has anyone used this filter? Is it worth it?
      Second, I also can't find anything on the suggested pump and min/max gph for this unit. It's not on their website or installation guide. Anyone know what that is?

      Never have seen one before. Diagrams from the manufacture show good flow distribution on the top and bottom. Many have just a simple single perforated pipe. Most pressurized filters like this have ratings that are very optimistic. Well known manufacture so parts shouldn't be an issue.

      Several manufactures now have bead type filters using larger media. They don't filter to tiny micron level a true bead filter does but they have less backpressure, backwash easier and not prone to caking.

      Have you thought about adding a small RDF?

      i know of a koi dealer that loved his. still need some prefiltration, so i will take a smaller rdf to diy shower all day though

      in my opinion this filter has side mount ports which are superior to top mount ports and dual flushing is
      great as the smaller media takes more to flush. when backflushing most the waste stays suspended so side mount and this is about the best a bead filter can get i feel

      Thanks BWG!
      We have thought about it, but it's not affordable right now while paying to finish my degree. Once I get to work we will make significant improvements- like an RDF. But, in the meantime, we need to add to what we have, hopefully adding both mechanical and biological filtration...

      That makes sense...but I didn't even think about the prefilter (still new at this). Do you have any suggestions for a system that won't "break the bank"?

      not sure what current setup is. if you could gravity fed a sieve then a ultra sieve 3 to either a diy shower or moving bed would be fine. if sieve can't be gravity fed them zakki sieve jr then to shower or moving bed would be fine

      Or a sieve to a couple DIY sand and gravel filters.

      I can't find any flow rate info either on the mfg site. There is a 2.5 bar (36.2 psi) pressure rating. A typical pond pump won't come close to this.

      This is made here in the UK, I have no first hand experience of the filter, but I spent quite a lot of time researching it last year and even called the manf. The general consensus seemed to be was that it’s about as good as it gets for a microbead type filter and if you don’t have the space for a normal filter it’s ok, however it was recommended to be used with a Cetus sieve.

      Are you after more Bio or better mech/fines filtration?

      Info I recieved.
      EA does not have a specification for pumps sizing in these pressure filters. Basically, and similar to other brands, the max flow rate isn't really important as long as you don't install a monster pump. What is more important is that you do not install a pump too small (like a Sequence 750 type). Although a small pump may work for bio-filtration, you need to have a pump with enough head pressure to get a good backwash. Most people figure at least a 1/4hp pump type. But you can use larger pumps up to 1hp (or more for the larger sized filters). Most find a good balance at the 1/3 to 1/2hp sizes.

      Actually we need both. Definitely better mechanical, which I"m sure will make the bio we already have more effective, but still, I add additional bacteria frequently along with lots of water changes. I would like to reduce the water changes from 25% daily to every other day if possible because the water is better

      I asked one of the guys in my local koi club who has one, this is what he said:

      Definitely needs a pre-filter before it, otherwise it clogs up quickly - basically needs cleaning everyday.

      The blower supplied with it is too small, doesn’t agitate the K1 all the way to the top when cleaning, so needs upgrading.

      Nexus 220 / 320 is better if you have the space (he has both)

      However it does work well enough and does good with water clarity.

      consider a ultra sieve 3 filter and then focus on the bio. could either do a moving bed filter or a shower for best results and simple maintainenece
