To UV sterilize or not?
×
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

Does anyone recommend the use of a UV water clarifier and what model for a 350 litre tank (e.g. 36W JBL AquaCristal UV-C Water Clarifier)? Will this work to prevent the water borne infectious diseases? For example >>
www.fishkeeping.co.uk/articles_88/white-spot.htm
Does anyone use a UV clarifier and are there any pros and cons to consider?
Also I note from >>
www.fishlore.com/uv_sterilizer.htm that it states - "For example, a 15 watt bulb will usually kill algae and bacteria with a 120 gph flow, but you will need to lower the flow rate to around 75 gph for it to effectively kill parasites." How does one achieve this with a JBL e1500 external filter (assuming 1500 lph / 396 gph)?

For what its worth I think they are nice to have, but not a need to have. Nice to have in case you do have an outbreak, something Im going through right now in a marine tank (marine ich), but they are not essential. Your fish will always have infections and parasites, kept in check by their immune systems. If an outbreak does occur, wc's, meds and finding the cause are the best routes to take in dealing with it. Treating ich in a marine tank is a little different though. The sterillizer will certainly help with the numbers of water borne bugs but wont get them all...

Hi as always pros and cons... i personally wouldnt use a UV 24/7 but id use it as a preventative when introducing new stock or if you do have a problem with WS. Big drawback is it can sterilize a system/tank and fish can become "weakened". The bulbs need to be changed 6-8 months to get the best out of them, however they are no substitute for good water quality

Just to add that if you have several tanks and you used a uv for one you should have uv for all unless you wont move the fishes around although this is highly debatable as some lfs have uv in their quarantine but when it comes back to our homes they are still ok when we have no UV!
This is prob due to the fact if the fish is exposed for a long time in an UV filtered tank; they will fare worse off in another that doesnt have it.
I think kev posted a really good article on this few weeks back. Personally for me; im not a fan unless some mishap happens. touch wood!
All the best!

I have a vecton 2 unit, have to say that since I have it I had less problems especially when putting new fish in and also tends to clear the tank from the greenish algae.

UV disinfection has become popular across a wide range of water treatment applications including aquaculture because it is a very effective non-chemical way to eliminate just about every organism that passes through it.
That said, there are many succesful aquarists and breeders who dont use them. I've heard stories from many aquarists who have tried them and say they find they dont make a lot of difference.
If you maintain a healthy environment with good water quality there is not much for the UV steriliser to "fix".
Trick is matching up the pump to the UV unit so you have the proper dwell time, otherwise, they're probably no use whatsoever.
