I have no idea....a friend loaned me one to use on my reef tank and I don't know what strength of pump I should use on it for it to sterilize efficiently...too fast will make it's efforts redundant... 
 
What do you guys use?

 any slow pump will do , the older the bulb less UV, so go slow flow  slow , just enough to Not overheat the UV unit .
