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
carbon filter pad ?
Activated carbon does have some amount of debate surrounding its use.
It does a number of things, but the main reason for use in a fish tank is to adsorb chemicals....with the hope that the chemicals adsorbed are poisons, gases etc. (but it is not particularly great in telling what is a poison and what is not !!).
Eventually, its adsorptive potential will be reached; it will also become clogged by gunge and bacterial colonies.
Normally, it is unlikely to release the poisons it has adsorbed. But it is also a catalyst....and it could catalyse the production of harmful compounds from much less harmful compounds.
Now, as said, that is unlikely to happen under normal operation but where there may be a danger is in attempts to 'regenerate' the carbon in a domestic oven.
Generally, if you don't replace it then it simply becomes a substrate for bacteria to grow...some may be part of the nitrogen cycle.
It can clog and it can slough off the bacterial colony if not maintained properly.
