s3xtcy Posted December 12, 2012 Report Share Posted December 12, 2012 Ive been looking at alot of videos of saltwater setups, and Ive found that it seems to be quite 50/50 as to whether or not they have a UV Sterilizer, My question is, is it necessary? And if it is, should I be running all the water between tank and sump through the filter, or should it be a smaller amount, say a recirculated amount in the sump, as to keep some of the good bacteria alive, rather than blasting it into oblivion? In this video I see he has a very nice looking white UV filter, that looks like it was designed to use PVC connections, everything Ive seen at my LFS and on trademe looks cheap and has multifit hose connections that you clamp down with hose clamps (if at all!) Can anyone point me in the right direction of a decent UV filter, similar to this one preferably, that has the ability to have the PVC connections? Thanks heaps Video : Time : 1:40 & 1:50 Quote Link to comment Share on other sites More sharing options...
reef Posted December 12, 2012 Report Share Posted December 12, 2012 Uv is not necessary, any good UV is going to cost over $600, most of the ones at the shop are toys. Quote Link to comment Share on other sites More sharing options...

si_sphinx Posted December 12, 2012 Report Share Posted December 12, 2012 I also looked at get a uv filter for my tank. They are very pricey as reef said. the LFS ones are a waste of money. The proper one I looked at getting was around $700-$800. I think I will spend this money on an upgrade to LEDs before this. I will get one eventually but for now I will go without.

s3xtcy Posted December 13, 2012 Author Report Share Posted December 13, 2012 Sweet, then they are obviousally in the "want at a later date, maybe" category. Lol thanks Quote Link to comment Share on other sites More sharing options...
livingart Posted December 13, 2012 Report Share Posted December 13, 2012 UV units only work on the water passing through them there is still a lot of untreated water in the rest of the system so you require a large unit to be effective Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 13, 2012 Report Share Posted December 13, 2012 what about the pond UV steralizers????, they do good work on algae, dunno about diseases though. Quote Link to comment Share on other sites More sharing options...
reef Posted December 13, 2012 Report Share Posted December 13, 2012 what about the pond UV steralizers????, they do good work on algae, dunno about diseases though. no good as they are designed for large flow so the water passing threw the UV has a far lower kill rate.

Ira Posted December 13, 2012 Report Share Posted December 13, 2012 no good as they are designed for large flow so the water passing threw the UV has a far lower kill rate. So...Decrease the flow? Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 13, 2012 Report Share Posted December 13, 2012 that was my thought, most UV units in ponds are rated for high flow but never get it, I know of 5w units rated for 3000LPH running fine with only 400LPH running through them, Quote Link to comment Share on other sites More sharing options...

Possibly the bulb might overheat, but I doubt that. Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 13, 2012 Report Share Posted December 13, 2012 correct me if im wrong but lower flow = higher exposure time Quote Link to comment Share on other sites More sharing options...
Ira Posted December 13, 2012 Report Share Posted December 13, 2012 correct me if im wrong but lower flow = higher exposure time Exactly my point. Lower flow=longer exposure=higher kill rate. That's why I'm saying, lower flow isn't going to make it less effective. Quote Link to comment Share on other sites More sharing options...
F15hguy Posted December 13, 2012 Report Share Posted December 13, 2012 my bad, same point different expression Quote Link to comment Share on other sites More sharing options...
reef Posted December 14, 2012 Report Share Posted December 14, 2012 So...Decrease the flow? pond UVs are designed for high flow as mentioned so there is a much bigger space between the bulbs and the water which means far less kill rate.
