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

Whats your alkalinity? And Magnesium levels?
did you test for these?

It still amazes me how often Magnesium is over looked by marine keepers. MAG levels should be kept at 1500ppm.
Calcium 450 ppm, Magnesium 1500ppm..3 Times more important
Magnesium is used in the growth of everything in your tank, from your Coraline algae right through to your fish. It also stabilizes your PH.
Your PH, for me, is too low.. i suspect your magnesium is low and ALK too, both work side by side.
Raise your Alk, Mag levels and your coraline algae should start to use your nice calcium levels to grow again..

Let me know if this helps and if your testing for ALK and
MAG.

sorry for getting back so late darkin.work as been hetic as is everyones i expect before christmas.Just to let you know i brought a sample of water down to the lfs for testing everything is fine with the water but they don,t check for magnesium or calcium and i think i was reading the salfin tests wrong.I am going to confirm the readings with paulm and kireon as i think they use these all the time.When i explained what was happening in the lfs they suggested putting iodene in the tank and it sould improve in a week or so.Thanks again for your advice its great to know theres help only a click away.

Does your LFS do marines?
Strange that they don't test for Mg and Ca:huh:

Adding iodine when not testing the levels, can cause you more problems, as your corals don't like elevated levels of this element!!
Get Keiron to test your ALK levels, your Ph is too low, did you mention that to your LFS???
