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

It is possible to over airate a tank but only in as far as too much air flow will cause the water surface to lift above the column of bubbles and spill over the side of the tank. Also, depending on the fish in the tank, you may cause too much of a current with the additional circulation of water. The addition of an airstone is not what gets the oxygen into the water, but rather the additional surface agitation allows better gas exchange at the surface.
Regarding the positioning of the air stone, it’s a matter of personal choice but it makes sense to keep close to the rear of the tank so as not to spoil the view of the fish. Given that the air will cause turbulence in the tank, it is preferable to place in any dead spots in the tank. So if you have any areas in the rear of the tank where food / debris typically accumulate, then this is the best place to position the airstone. It will lift the debris into the water column and allow the filter to remove it.
Hope this helps.
Cheers,
Bill.

If you are looking to grow lots of plants then air stones are a no no.
I'm no expert but that was the advise in one of the amazonas mags on CO2 and planted aquarium.
Having said that they do look good!

I thought an air stone would have no effect on plant growth ?

'Running an air pump is like shaking a bottle of soda Or beer: the CO2 will be driven out of the water. So give your air pump a well deserved rest. '
How much it will affect plant growth I don't know. I'm guessing it probably is refferring to heavily planted tanks as I've seen lots of tanks with plants and air stones.
I'm sure some of the more knowledgable posters will be able to shed some light on it if you excuse the pun!

It would depend on the plants.
I find that Bolbitis will not grow well unless it has a good current by it (and an air-stone is perfect).
On the original question, not all fish take too kindly to strong surface agitation.
If you are pumping too much ozone into the tank then that would also be a concern as over-aeration.
So, yes, if too much ozone is being pumped in then over-aeration is not a good thing. But with a normal perfectly working air-pump that should not happen.
