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

I have been using rain water to do water changes in my pond for several years now. I was collecting this from the polycarbonate roof of our conservatory, now this has been changed to a solid light weigh roof this is an aluminium tiles effect roof , just wondering would it be safe to rain water off this type of roof . I would of coarse not use the water off it for an initial period .

Hi Robert my tuppence worth would be that having alluminium contact with water for part changing purposes would be a no no,if it had a surface coating over it in its manufacturing so theres no direct contact i,d say then it would be ok.Just like having a new copper hot water cylinder and pipework would be detrimental to the fish with the copper concentration,see what other responses you get though before making a decision ...

www.nationalfishpharm.com/koipond/water_quality.html "Run-off water from a nearby stream, or collected rainwater may contain toxic insecticides, herbicides or fertilizers. Rainwater from metal roofs or asbestos shingles will contaminate the pond and may prove toxic to both the fis h, and the plants. If the fish display signs of toxicity, execute a 50% water change and/or remove the fish to safe quarters, or a hospital tank until the water has been changed" .......maybe be safer than sorry and use your tapwater with a good water conditioner like tetra aquasafe while the water war is ongoing and address this issue in the future.

The toxic effects of aluminium depend on the aluminium compounds formed, and pH can be part of that.

Remember that clays are aluminium compounds...........but not in a form likely to cause problems.
In many blackwaters you may find aluminium compounds.

But, aluminium should be considered toxic in the form you talk about especially in generally acidic water.
However, silicic acid or other silicon rich acid waters can abrogate or reduce aluminium toxicity.

In acid waters, especially, there is a noted ionoregulatory gill dysfunction in aluminium poisoning....and that can also be in concert with osmoregulatory problems.

The chances are that the rain is acidic and further chances are that you don't have a silicic acid (or other acid silicon compound) in your waters unless your water runs over natural clays or other aluminiumsilicates.
