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

Have the DD one and its so esy to use, just have to make sure you calbriate it properly or your readings will be off but i am sure this is true for all refractometer. It also has a temperature compensation built in so it will read the true value of salt content within a large temperature range thus giving you a true value reading.

The DD is the only one i ever had so can,t comment on other makes but i would definitely give it a bigs thumbs up.

With the DD you don,t need any calibration fluid just some RO water, drop it on the refractometer and zero the device. You can then take readings from your water you wish to test.

Easy as that, i say most refractomter operate on the same principle
