Retirement and forum shutdown (17 Jan 2022)


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

JBL Product confusion - help?

30 Jun 2021 18:21 #1 by BenEadir (John Murray)
Hi all,

I run a 600L Malawi Cichild (approx 60 mostly mature Cichlids and 5 common Plecos) aquarium with 2 X JBL 1502 filters and after many years have managed to get to a point where the Nitrate cycle appears to be completing to the extent that water chemistry is consistently very good month on month including Nitrate close to 0 PPM the big benefit of which is over the last 18 months or so I'm only topping up the tank once a month to replace evaporated water and cleaning and rinsing the filters (in acquirium water) on an alternating basis every 6 months at which point I do a 50% water change. (I'm OCD about getting the water chemistry readings right so use 2 different test kits to verify my monthly check.) 

My setup in each filter is identical and fairly simple

Bottom tray - 30 PPI foam
Middle 2 trays - JBL MicroMec (www.jbl.de/en/products/detail/2418/jbl-micromec?country=ie
Top Tray - 30 PPI Foam.

I just noticed that JBL have another mechanical product called BioNitratEx (www.jbl.de/en/products/detail/8032/jbl-bionitratex?country=ie) which seems to be designed to do the same or a similar job to MicroMec but for the life of me I can't see what the functional difference between the products is or what the advantages of one over the other are?

Can anyone illuminate me?
