ghostface Posted March 31, 2006 Report Share Posted March 31, 2006 who uses U.V.? if so, what hours are you running it daily, or are some only using it to treat probs as they occur? i have 36w running on 800l setup. ran it 24/7 for a few days, now have it on 12hrs-on 12hrs-off cycle. makes the skimmer go nuts, i have it running sump - carbon reactor - uv - skimmer - sump.

chimera Posted March 31, 2006 Report Share Posted March 31, 2006 hows the uv running layton? any improvements? is the ap902 skimming harder now? Quote Link to comment Share on other sites More sharing options...
lduncan Posted March 31, 2006 Report Share Posted March 31, 2006 Yes. The UV made a significant impact on skimmer output. I empty the cup on the 902 everyday. It's usually bubbling over by the next morning. I need to get a second one to keep up. Layton Quote Link to comment Share on other sites More sharing options...
ghostface Posted March 31, 2006 Author Report Share Posted March 31, 2006 i am having to empty the 850 cup once every 2 days now, instead of around once a week. ld what hours are you running UV? 24/7 or...... Quote Link to comment Share on other sites More sharing options...
lduncan Posted March 31, 2006 Report Share Posted March 31, 2006 24/7, no real reason to run it any less. You might as well get the most out of it. Layton Quote Link to comment Share on other sites More sharing options...
slappers Posted April 1, 2006 Report Share Posted April 1, 2006 so should eveyone use UV Quote Link to comment Share on other sites More sharing options...
lduncan Posted April 1, 2006 Report Share Posted April 1, 2006 I don't determine what people use or how they chose to run their tank. I give the information which means that they can make that decision for themselves. People have different requirements and different standards for their tanks than what I might have. For my tank and the type of animals I keep, UV is a very useful component. Layton Quote Link to comment Share on other sites More sharing options...
beachy Posted April 1, 2006 Report Share Posted April 1, 2006 I have used uv on a number of freshwater tanks, using it gives you real crystal clear water. I have used proper aquarium uv, and pond uv (on fresh aquaria), both work well, but i would say proper aquarium high watt uv would be the call on a s/w tank.

wasp Posted April 1, 2006 Report Share Posted April 1, 2006 Well if it increases skimmate by the huge amounts you say, I may have to revise my opinion on the device. How long term is this increase in skimmate? A few weeks, or longer? Quote Link to comment Share on other sites More sharing options...
slappers Posted April 1, 2006 Report Share Posted April 1, 2006 hmm i might have a play with one tomorrow Quote Link to comment Share on other sites More sharing options...
Fay Posted April 1, 2006 Report Share Posted April 1, 2006 Don't understand I thought the rock in the tank keep things clean if you kill the stuff that lives in it wouldn't that be bad? For my tank and the type of animals I keep, UV is a very useful component. So would it be bad for animals like anemones? Quote Link to comment Share on other sites More sharing options...

lduncan Posted April 1, 2006 Report Share Posted April 1, 2006 well i will get one today and see if i can see any diffrents Careful what brand you get. Not all UV's are created equal. You need a HO one. Many of the Asian brands use bulbs which have glass envelopes, but then use quartz sleeves. You need one which has bulbs which have quartz envelopes and sleeves. Normal glass blocks a significant amount of UV. The Deltec ones are one of the least expensive ones I have seen. Emperor in the states also make good ones, but I don't think they do 240V versions. Fay, i'm putting together an answer for you. But most of what you want to know is probably here already: http://www.fnzas.org.nz/fishroom/1-vt10335.html?start=0 Layton Quote Link to comment Share on other sites More sharing options...

lduncan Posted April 1, 2006 Report Share Posted April 1, 2006 UV Basics: • The UV light breaks chemical bonds within molecules. Specifically carbon double bonds. This results in smaller molecules. • Bacteria are more efficient at using these resulting smaller molecules than the bigger ones which were there before the UV zapped them. • With this smaller food now available, bacteria populations increase faster and hence more skimmate is produced. (Bacteria and phyto are major components of skimmate) • Many of the chemicals released by algae and corals which are used in chemical warfare between species are neutralised by UV. • UV kills (or maims) living things which flow through it. (Including bacteria, phyto, parasites, and zooplankton) But these would be removed by a skimmer anyway, so what does it matter if they are dead or alive. • UV promotes denitrification by boosting bacteria activity and populations within rocks and on surfaces throughout the aquarium. This is the hardest thing for people to grasp. UV actually increases the bacteria you want in your tank. All this comes down to one thing. Transforming waste within the tank into a form which can be permanently removed by skimming efficiently. Basically it makes your skimmer skim more. Removing more waste faster.

Fay Posted April 1, 2006 Report Share Posted April 1, 2006 Thanks sounds good • UV kills (or maims) living things which flow through it.

So what about my Anemones do they use any of the above from the water? Quote Link to comment Share on other sites More sharing options...
