 |  UV LIGHT (newbee question)
I just bought on ebay a jebo 13w uv light with pump ... i have it on a 46 gallon bow front tank ... and only a couple of clown fish and 3 small frags... and a few pecies of live rock.... 
just wanted to know if i should run the uv light with pump 24/7 or should i set it up with the timer??? 
I have been running it about 12 to 8 hours a day for the last week .... and i have noticed a diffrence in water ... and the corals seem to be brighter in color... |

I run it non-stop. Who told you to run for a determined set of hours? When I researched it, it would mention to run it all the time.

| Second, third, fourth that?
I do not have one. However, the reason for running 24/7 is the flow rate is so slow (to allow contact time, sort of like a microwave) that turnover for a full tank requires lots of time. In a very real sense you can never run all of the water (thus pathogens) through the UV because it follows an exponential curve. 98% is a good number, no?
Enjoy your cleaner water and brighter corals.  _________ Glass 90 and 110, skimmer in both 30 gal. sumps, 1150 GPH, plus a 75 gal fuge!! Yellow tang, several damsels, 2 lg flower anems, brown & rose BTA's (8" dia.) with 3 perculas, 5 ricordia, dozens shrooms, dozens of yellow, brown and green polyps, lots of snails, hermits, bugs and 3 inch worms.
