Do you run UV sterilization?
 

1. Yes
2. No
3. Yes, but don't think it does anything.
4. No, but want to.

Can someone explain to me why this is a good thing to have?

floating bacteria and other living stuff will pass under intense UV light, which kills the living stuff in the water. This can often help make sure that you kill parasites, viruses, bacteria, etc which would normally just survive in your water and cause you problems.

Running Zeo I can't but I did before for about a year. Then I went to check on the bulb and the thing was burnt out. Don't know how long it wasn't working but figured if I didn't miss it why keep it. Never had any problems with disease
Actually think it kills more good stuff than bad

I find strong UV (40w+) helped to keep ick-magnets like Powder Blue Tangs healthy & alive.

I now have a 80w on my 210g & my 40w (needs new bulb) with a temporary 25w (till I get a new bulb for the 40 watter).

I wouldn't bother trying to keep ick-magnet tangs without one.

Chin has a 80w UV and ozone on his system & that probably accounts for the recovery of his very icky Achilles tang this week.

OK...I should reword that....I understand what UV disinfection is for but it isnt just killing the bad stuff in the water.......this is more what I am asking because its killing everything that goes through it.

My achillies tang went through about the same sequence of attack/recovery as his...but I don't have a UV sterilizer. Obviously, his running of UV didn't prevent the ick attack in the first place. This makes me wonder if the UV is at all effective against ick.

Very good for fish only tank

As I am on ZEOvit I can not use UV.

Prior to the use of ZEOvit I used UV rather sparingly to control algae and disease. Turn it on for a couple of days and your yellowy green water becomes crystal clear.

It went into the tank with ick from transport stress. If it wasn't for the UV & ozone, I don't think that an ick-magnet that is notoriously difficult to ship would have recovered that fast since the ick would have kept on reinfecting the Achilles if they hadn't been killed off by the UV & Ozone.
