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

I just noticed in my community planted tank that the fertiliser substrate has gone a black colour. For my substrate I have JBL aquabasis plus underneath regular pea gravel.
I can see the substrate in different parts of the tank and its fine but on one end there's a band of black between the gravel and normal coloured fertiliser substrate.
Any idea what that's all about? Should I be worried?
Water parameters are all within normal limits.
I have a photograph of it but I need a cable to transfer off the iphone which is in work! Will post pic when I can.
Any idea's what it might be in the meantime?

i think its lack of oxygen allowing a form of bacteria to grow i would start moving the strata to allow oxygen in more when cleaning. but could be mistaken

Hey,I agree with Mickeywallace.looks like anaerobic bacteria,some people use Melanoides(Malaysian trumpet snails) to aerate the substrate ,which would get rid of it,but most people try to get rid of them so not sure you want to introduce them in your planted tank:lol:

Hi. You can use the MTS, and then later to get rid of them or control their population, you can use Anentome helena - killer snails. In the future, avoid using a thick layer of sand or try to use sand mix with gravel.

Thanks for the heads up. I'll pick up some MTS then.
I'll stick a post up on the wanted forum in case anyone on here sells them
Thanks,
Neil
