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

Can anyone tell me if Activated Charcoal strips any nutrient added to a planted tank?

Now to answer your question I remember reading interesting debate on one of the planted forums.
The conclusion was that it does remove fertilizers and appears to affect more micro nutrients than macro.
It's not bad to use activated carbon as it does add some benefits.
So if you want to use it you'll have to dose a bit more.

As mentioned just dose a little extra nutrients.

It doesn't remove everything....and just as well.

would a polyfilter have the same effect as carbon
john
Personally I doubt Polyfilter does what it says on the tin. If it did, there would be no need for activated carbon or other resins that use ion exchange. Also, its claimed that the salty version of the stuff eliminates the need for protein skimming...bolderdash if you ask me. Yet another miracle product thats yet to live up to its claims.

But, from a chemical point of view.....it is possible that PolyFilter CAN do what is says (not that I use it, but maybe I should give it a run). If it has various zeolite (or similar catalysts) components bonded then it can do possibly some extraordinary things. There has been some great leap forwards in specifically designed zeolite catalysts/adsorprion/absorption/chemisorbents etc etc.
It also sounds as though Polyfilter has some ion-exchange capabilities.....but, again, are the manufacturers being a bit coy about that?
Carbon can do multiple things...generally, it is used for it adsorption qualities. But there may also be some absoroption and chemisorption happening as well. And with adsorption, there is also the opportunity for speeding up chemical breakdown (if molecules are held in close proximity).
Carbon will also act as mechanical filter to some extent, and (if local conditions are right) will hold bacteria for biological filtration. Not that these points are the main reasons for using carbon....just side uses.
Would I be cautious of using the latest greatest invention? maybe, but maybe always worth further investigation.
