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 bought a new juwel 240 about 6mts ago and was told by a friend that the light units give trouble,
that water can get in very easily and it is then fooked
so they need to be DIY sealed with tank reseal silicone around the 4 fittings (if yea no were i mean 2 at each end)
now their is a seal around them kinda like a washer thing looks safe to me but yea no urself dont want to hear the owl 'i told yea
any input would be great
thanks in advance lads

I found that, in my case anyway, the Tubes are to blame or should I say, the metal Cups at both ends are, I found that, after a while, they loosen from the Glass, my advice would be to put something like an Epoxy Glue around the area where Glass and Metal ends come together , I did this and resolved an on-going horror with these Lights. (Not sure on which type of glue/solvent/Silicone is best)

its actually on the light bulbs / tubes themselves. The metal endcaps can come loose. The lights start to flicker and act up. It can in turn cause damage to the ballast.

dont seal the screw on caps, they can be replaced quite cheaply if the rubber seal is loose on them, some of the better LFS will stock them as spare parts. The seal with silicone or epoxy should be placed in a band around the join between the tube and the metal end cap, so where the electrical contacts meet the glass. Not sure if I am making sense, if not let me know and I can post pic showing where I mean.
Cheers,
Bill.

referring to the pic attached, the seal that fails on the tubes is where the metal endcap meets the glass. The endcap is held in place with a thermoset glue but it often fails on these tubes and leads to problems. So a thin film of silicone or opoxy around that stops the problem. Hope this helps

Hi only got around to doing my sealing tonight as we know the silicone is messy stuff their is silicone on the bulb it self like a couple of mill,, is this ok, i will leave it dry for 48hrs before putting the unit back on the tank and turning it on. Will the heat melt of soften the silicone that will then fall off and into the tank??
