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

Just tested my tap water for pH and got a value of 7.5, i also had tap water sitting in a glass for a couple of days and the pH value of that was 9.

Am thinking that the pH of 9 is my true reading as it had time to settle instead of the running tap.......am taughts from anyone???

Cheers

hi gerry

im no expert but yes the sitting water
would be more like your tank water
unless you do daily w/c's!

in my limited experience
i found the whole ph thing overhyped
when it comes to fish health

i had wild swings when i introduced diy co2
to my established tank and no casualities

It depends on the fish that you are talking about. Swings in pH is not good and can be fatal. pH is a log scale so the difference between 6.0 and 7.0 is one hundred times greater. So pH 5.0 is 100 times more acidic than pH 6.0 and so on.

Fish need to adjust their blood to the pH of the water to enable them to absorb oxygen through their gills and it is very stress full to have the pH change faster than they can make the adjustment, for that reason, you should acclimatise fish to new pH and never move the pH more than .5 in one go or 1 in a whole day.

I can never remember whether moving up is less stressful than moving down, or the other way around, but regardless you should try to avoid swings either way. A big swing may not kill a fish instantly but the stress can lead to the fish becoming victim to an ailment they would have otherwise have been able to fight off...

hi darragh

i bow to experience as always
and sure some are sensitive (eg discus)

its just my limited experience (thats my disclaimer ;) )
i got swings of 1 when i set my diy co2 up
got into a panic and onto the ukaps forum
where I was advised to chill the f out about it all! :laugh:
and was told that while its certainly not an urban legend
ph swings are way overhyped

my fish are rugged silvertip tetra and not so rugged oto

regards
