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

Anyone know anything about the above as a buffer?

Best to experiment with smal dosed of your water to get a more accurate reading.
I use bi carbonate soda (Bread soad)to buffer my Malawi water and it works a treat.
Ph up is expensive and it either does not work or is only temporary.

Dont know anything about Koi ponds, but i do know that bicarbonate of soda and calcuim carbonate are 2 different things, if you buffer your water with bicarb of soda this will raise your KH, if you buffer your water with calcuim carbonate you will raise your KH and your GH.

One thing with calcuim carbonate is that is very hard to dissolve, much easier to use calcium chloride.

I think you will find that both of these products contain simular properties
Try this link, it could explain a little further than I went.
www.practical-water-gardens.com/how_koi_ponds_work.htm

see
The pH in a koi pond is under regular pressure from the by-products of biofiltration. When koi excrete ammonia into the pond, the processing of that toxic compound into nitrite by bacteria will inevitably release free hydrogen ions causing the water to become more acidic.

NH4+ + O2 --> NO2- + 4H+ ... Ammonia is converted by bacteria in the presence of oxygen into nitrite, releasing free hydrogen ions into the water

Now who is the rocket scientist that started this lol

In simpler terms..

Nitrate= Niitric acid. Nitric acid eats in to the kh (your buffer)of your water. If your kh drops to one or less your ph will start to crash.
