andrem Posted January 9, 2007 Author Report Share Posted January 9, 2007 I am running same brand as steve but 18w. After about 3 - 4 weeks my skimmer output is back to what it was prior the UV unit install, however my tank has only been matured for about 2-3 months, I started adding vodka a month ago (had new tank syndrome) now have no nuisance algae and coraline algae is growing VERY quickly as are my corals (am certain the UV unit also helped remove the problem alage. I did have problems with whitepsot which is why I added the uv unit in the first place it got rid of the whitespot on the fish, but added some new fish a week ago and now have a small whitespt outbreak on those fish a couple days ago, fish continued to feed happily and normal behaviour in all other ways today only very very few spots remain. I concede that this unit is probably not as good as some of the other brands that are out there but without I think I could have suffered a major whitepot outbreak without it and probable losses.

reef Posted January 9, 2007 Report Share Posted January 9, 2007 Uv won’t remove white spot on a fish ,it kills the free floating white spot, eggs. Whitespot does not kill fish it is the bacteria that generally kills fish once the white spot leaves small holes in the fish. An 18w Uv will be ok for killing algae however unlikely to kill parasites and bacteria as it is too small. Even a 54w uv can only handle 2000L of water thru put, anymore and then you won’t get the killing power required. Also quartz uvs are the best. on the "kill power" needed for the corresponding Micro-Organisms. Waterborne Algae 15,000 to 30,000 æW sec/cm2 Common Bacteria 15,000 to 30,000 æW sec/cm2 Protozoa (Ich) 45,000 æW sec/cm2 Fungi 45,000 æW sec/cm2 what fish did you add?

jetskisteve Posted January 9, 2007 Report Share Posted January 9, 2007 thats like saying a mercedes will get u from point A to point B but a toyota wont. ANY UV is better than NO UV Quote Link to comment Share on other sites More sharing options...
reef Posted January 9, 2007 Report Share Posted January 9, 2007 so its like saying a 18w UV will kill 1/2 a parasite. so it is better than nothing. All information states that you need the killing power at a certain level to kill parasties. so any UV wont work. ANY UV is better than NO UV Another sales pitch to me.

andrem Posted January 9, 2007 Author Report Share Posted January 9, 2007 added a fish from an LFS. I can only make comments on my personal experience with the UV unit I have been using. The whitespot was actually on the fins of the fish and not the body. Today all white spot gone. Fish behaving normally in every other way. I note from reading previous posts that others have had similar experience with similar units to mine. I am not trying to sell any one product or the other am just commenting on what results I have noticed in my tank with the equipment I use. I would however like to try one of these 54w units (or something similar) and see if I get any different results. Quote Link to comment Share on other sites More sharing options...
wasp Posted January 10, 2007 Report Share Posted January 10, 2007 Doubled my skimmer output lasted a month or so and now its back to normal :-? quess the u.v + skimmer did a clean up. Is your water clearer now on an ongoing basis? Quote Link to comment Share on other sites More sharing options...
shaneo Posted January 11, 2007 Report Share Posted January 11, 2007 yes, and sps have coloured up more too. I guess due to better light penetration? Quote Link to comment Share on other sites More sharing options...
