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

Aeration and PH

Can excessive/extra aeration in an aquarium affect PH levels?

Yes.

ian


just yes, without any explanation?
Who are you and what you did with Ian? :lol:


Someone who is trying to do some work on a discus tank in which one of the main filters has broken.

But, yeah, just 'Yes'.
But how much it affects pH depends on various things.

Yes it will normally increase PH.

One way is it's effect on Co2 (carbon dioxide) in the water.
Co2 mixed with water forms carbonic acid which lowers the PH.

You dont have to intentionally add Co2 to the water, it happens through fish respiration, plants and algae respire after lights out giving off Co2 and gas exchange at the waters surface taking in some Co2 from the air.

Aeration drives off Co2 which in turn raises PH.

If you are just adding an air stone it wont be the aesthetically pleasing bubbles that add all the oxygen. Most if not all of this will happen at the water surface were the bubbles break the surface causing gas exchange and driving off the Co2. This in turn increases the PH.
