Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

I am not familiar with that media, so cannot comment on the use of it. Maybe I should google it.
The main thing that I always found tricky with home-made experimental filtration is more of the mechanics that hold together without flooding the place (eg having cycling Sohxlet wet-n-dry filtration where the influx was faster than the output tubes could cope with.....but that is the fun).
In the early days, experimenting with reverse flow air-driven undergravel filtration had loads of teething problems of air getting under the filter plate and slowly raising it. But....trial and error....and got it right and very effective eventually.
Air-driven fluidised filters are a goer. So....go for it.
I'm not going to draw diagrams here, but I recon you can easily come up with something viable.

Not sure if that's what my wife would call flooding... fun

As for flooding when making experimental filters.....it made little difference in the early days as even many of the bought external power filters would quite often flood your room (especially some early hang-on external power filters).

k1 is good but there is a new version out with 40% (i think) more surface area if you want to look for it on ebay because thats where i seen it.
i know 1 other bloke who uses it in a compartment of his sump but don't think he's on here. when i was considering filter options for my big build i was gonna use a 25L drum to fluidize k1 but unfortunately it never materialized (or fluidized

Below tank is for sale

I was thinking of 1 1/2 to 2 litres in a setup very similar to yours

Is it just me or did anyone else imagine a drumroll and a clash of cymbals when he said that?
Drum roll and cymbal clash...

couple of pics of my filter,1000 liters of mechanical and static media (hundreds of pot scrubbers).then 1000 liter plastic tank with bout 400 liters of fluidised k1.the fluidised k1 and biocell needs no maintenance,i made a plastic pipe airstone with hundreds of 1/16 holes drilled in it so it never clogs.the fluidised k1 seems to work great,but can take a fairly long time to mature,puttin fresh k1 in a bucket with some sharp sand and shaking a while will roughen the media and bacteria should colonise quicker.my k1 is fed from 4" dia homemade airlifts,but intrduced as part of a sump or easy made diy filter u should have little problems ,i,m very happy with mine.50 liters of media should deal with 1 pound of feed a day.often i have often fed over 3-4 ibs of feed to fish in one sittin without any water parameter problems later.only prob is the maturation rate,but if introduced with other working mature filter and slowly phasing ont old filter or aquiring mature media ,there should b no bother
