RE: UV lighting?

Seen that Phil... what a steal.

I don't really care for the units with wipers though since they tend to leak over time. I know you can replace the seals, but it's just one more thing to have to worry about.

A 57W for about $160 or so total, would be a great price and should be a workable setup for a pretty large tank. You could always replace the wiper seal at the same time you change bulbs, that would probably eliminate the leak problem.

What abut for my little ole 60g? Any opinions on what I posted about? O)

 

[ppurcell]

I've never used a JBJ and have no idea on their effectiveness. I did have Jebo 18W on my 75 for about a year or so which I think did ok for killing bacteria and the like at a low flow but I don't think it was large enough based only on the information that thread Mike posted to have a major impact on sequestering phosphates.

poo-tang: I've used acrylic baffles in my glass sump without problem. You will just need more silicone; probably more than you want to use but after almost three years in my sump I cut the silicone with a razor blade and still wrestle the baffles out when I pulled the sump out of service. I think I had about 3/16"-1/4" on either side of the baffle.

So for a 60w you think I am needing something much much much larger then 9w eh? O) Who am I kidding you have a bagilion watts on your 75! haha

 

[BreadmanMike]

I'd grab a 25w AquaUV for your 60g.

 

[ppurcell]

dunno, I have no real idea if they are as effective as people think they are. I do know that I have had no issues with ich in my tank since I started using UV. Phosphate is another matter. Since it is pretty hard to measure I don't really know if my UV works well as I hope it does. I still use GFO and grow chaeto and run a oversized skimmer too. If I had a colorometer I might experiment with turning it off for a while then turning it back on to see if I could measure a difference.

Damn thats about twice as much as I wanted to spend and probably 3x larger.Not to mention I need to get 1200gph going through that thing, thats 2x the size of my return pump alone! haha

I remember reading that the UV lamp loses half of its output fairly quickly, so I am sure you want an over sized unit.

400gph tops Slow is better.

Yeah, but thats a lot less flow! haha Thats going to nuke everything that passes through it. ha

Even so thats another huge pump I have to try and find room for. I don't want it running after my fuge, so I need to fit that pump into my first chamber with my skimmer.

Maybe I will hold off on this one and just run ozone.

can you run these on the drain side, via gravity? possibly tee off and put a vavle on the outlet side of the UV, so you can choke back and control the flow thru it? that could be just the solution u need Dan.

 

[BreadmanMike]

You're supposed to run clean water through them, so it would be better to T off the return and feed it that way.

 

[JNye]

what's so dirty about drain water compared to re3turn water? because of surface skimming?
