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 explain???

Just back from 10 days of glorious sunshine in Turkey. I did water change on my mbuna setupday before I went and my son was taking care of daily feeding. The day after I got back, I discovered the filter and heater were both off. Panic! I immediately turned both on again,tested water, readings were Ammonia 0.25, Nitrite 0, and Nitrate 5. Did a large water change and dosed with easylife and everything is fine. The fish are all happy and there isn't a single loss.

Although I am extremely happy and relieved,I am somewhat bewildered as to how I 'escaped' this potential disaster.

Your thoughts please

Hi Christy, the ammonia would have crept up gradually and fish can adapt to poor water conditions if this happens slowly... also as the temp would have dropped the cooling down of the water would have slowed their metabolism down and they would have used less oxygen and cooler water holds more oxygen... you were lucky tho, as they would have to be very healthy to put up with this....fish are adaptable as long as they are healthy and kept in a healthy well maintained tank B)

Also depends on how long they were off.
It also been warm out too bar one or two cooler nights.
A friend of mine lost half his stock when his son turned everything off one night
cos the water returning from the filter was disturbing watching the tv.
He noticed 2 or 3 days later.
He only had to put the pipe under the water level.

It would really depend mainly on the temperature and the pH.

Your test kit probably does not measure ammonia per se but measures ammonia and ammonium.

The % ammonia as a proportion of total ammonia/ammonium in your water will drop with lowered temperature and lowered pH (which may have happened with a filter crash anyway….even in a malawi tank where the alkalinity has dropped).

Somewhere in the Water and Health section here are some graphs of how the proportion of ammonia depends upon temp and pH.

Ie the explanation is more likely to do with the interpretation of the ammonia test result rather than any other bizarre process.

But, the fact that the fish survive indicate that the water was in good condition anyway.

The biggest danger here, though, was when you re-powered up the filter: external filters are the worst for wiping out a tank from toxic compounds being churned back into the tank from billions of dead bacteria.
