Posted	U.V STERILISERS
26-07-2006 19:09 by thomas	I AM CUIOUS ABOUT THE STERILISERS AND WHAT WOULD HAPPEN IF INSTALLED IN A TROPICAL SETUP, I DONT THINK IT COULD DO ANY HARM AND IT PROBOBLY KEEP THE GREEN WATER DOWN TOO, BUT I WANT TO HEAR EVERYONE ELSES POINT OF VIEW, THANKS AGAIN GUYS YOU ALL ROCK.
26-07-2006 19:13 by Penny1	i have one in my cichlid 5ft tank and it really helps to keep the algae down and water clear
26-07-2006 19:58 by seawolf	hi there ive put a hozelock 9000 over the top of my 300 litre chiclid tank, with a 1500 lph pump conected to it ,this has a built in uv and deals with big waist particles as well. never seen my tank and fish look so well, only down side is the big black filter box on the top.
27-07-2006 07:32 by thomas	how long do you have it on through the day, and what is the best method for water flow filter or powerhead.
27-07-2006 07:39 by thomas	penny1 what sortof cichlids do you have, any oscars or uarus.
27-07-2006 08:25 by PaddyD	No it cannot do any harm, aquarium uv's are designed for use in trop tanks. Eithe method of pumping water through would be ok, but after it flows through the UV you would want it to go into a filter. Remember that there are 2 types. Pond UV's will just tke out green water, while an aquarium uv will kill of lots of parasites etc. and keep the water clean and your fish healthey. I would run it 24 hours a day attached to your filter.
27-07-2006 09:09 by Alan	It is best to run them after a filter that way they will not get clogged with debris. The other advantage of UV sterilizers is that they produce a small amount of ozone that helps oxidize waste this in theory will reduce the staining of the water. Make sure you get the flow rate right though if it is to fast the effects of it will be diminished. I wouldn't be without one on a reef and have long considered one on a trop tank but have never bothered. Perhaps when they get a bit cheaper or when they do an internal one rigged up to a power head. Should be on 24 hours a day though.
27-07-2006 14:51 by Linda Chenapa	I have one on my seven and a half foot tank, mainly because I have stingrays in it. A UVS kills parasites that have a free swimming stage. Needs to be on 24/7
27-07-2006 18:37 by Penny1	Hi Thomas, no i don't have any oscars. I have malawi's which consist of zebras, fuellaborni's, malawi dolphins, red zebra, yellow labs, johanni's, auratus , 3plecs and 2 upsidedown catfish.
27-07-2006 19:08 by von	Hi Linda, long time no hear! alls well i hope.
27-07-2006 19:16 by trik	if the flow rate through a UV is to slow you will make things in your tank alot worse, algea blooms, parasites, to fast and it doesnt work at all. As an guide only: 8 watt needs a flow of 725Lhr for a 180 litre tank. 15w 1360Lhr FOR 365 litre tank. 25w 1820 Lhr for a 455 litre tank. 30w 2045 Lhr for a 680 litre tank and 50W 2275 Lhr for a 910 Litre tank, you could stick two in series to give a more pronounced effect; flow rates can be mulitplied accordingly.
27-07-2006 20:53 by Linda Chenapa	von - Yes all fine thanks, 6 weeks hoilday!! Waiting for granchild no. 6 to be born in about 9 weeks. No. 7 due in Feruary next year!
28-07-2006 09:08 by von	I knew i should of stayed in childcare! 6 weeks, i'm jealous You'll need it though all those babies to baby sit for!
28-07-2006 09:57 by keith t	I have an internal uv which i bought of ebay comes with its own powerhead, quite cheap aswell. its not bad as it can be hidden away behind some wood or rocks. good alternative to the more expensive outside ones.
29-07-2006 10:41 by thomas	ahhhhhhhhhhh got me a vecton 25w for a four foot tank that should be the dogs, anyone think that connecting it to a fluval 305 or 204 what do you guys reakon is best.
