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

Dropped my aquaray 500 in the water and after a lot of drying only 2 leds still work and dimly unless I actually press on the foil or printed circuit. anyone have the wherewithal to fix these or even resue the leds and the frame to get it working as a unit again even if not the original wiring

Thanks

Just a thought - is it fully dried out?
I dropped a phone in the water of a tank (I realise it isn't the same) and after three days in the sun (on the dashboard) it worked again - and has worked ever since.

How old are the lights, are they still under warranty???


I have seen on other forums similar problems with lads accidentially dropping they Aquarays in the tank and them being replaced by TMC.

The reason TMC replaced them is that the light has an IP rating that should make them ok to be submerged in water, the instructions with the lights clearly state that the lights are not to be submerged in water but i think as a act of good will TMC agreed to replace the units.

I suppose there is a grey area that TMC didn,t want to explore, if a product has a suitable IP rating stating that it can be submerged in water and there products fail when accidentiallly submerged in water is the product up to the IP rating.

HTH

The "lead-free solder" (rubbish. Doesn't like water, or high humidity. Hates salt) probably has turned to aluminium oxide (white powder!). A bit of a clean and 10 minutes with a soldering iron should fix it.

yes lots of white powder but they appear to be mounted on 'paper' with a metal backing (heatsink??) and these have come apart. the white powder is probably shorting the circuit.
Tried the cleaning but no joy. What about the soldering iron - build a new circuit ?

If the white powder is oily, its Zinc oxide and sillicone oil and is heat conductive.
It should be between the LED's and the heatsink.
If the solder has oxodised, it forms a dry fine powder. This is what needs to be removed.
The problem then is to re-solder the contacts of the LED to the circuit board, which is where the iron comes in. (fine-tipped temp controled).
Normally, things have not gotten so bad and all that is required is to brush the powder off and heat the joint, perhaps applying fresh solder. (Don't mix types!!!! Lead-tin-aluminium-(other stuff more dangerous than lead but not banned by the Eu yet) alloys are not very stable.)


Try the TMC route and see how you go.
If no joy, send me a PM.
