Because of some green water problems, I want to hook up my Lifeguard QL8 sterilizer to the output (return) of my Eheim 2229 filter. Is this a satisfactory method of doing it? I've heard flow rates need to be low, I hope the Eheim will not be too much. I have previously used a separate pump to provide flow through the sterilizer, but the hookup was a pain, with additional fill/return lines needed, etc. I'm thinking of using a timer to turn on/off the sterilizer, and was wondering how long it should be run? Would it be a good idea to run it for a specified time, all the time, or just when green water/fuzz algae appear? And is running the sterilizer detrimental to micro nutrients, as I've heard? For those that use the sterilizer, and if it is detrimental to micros, what do you do for a service regimen to avoid this and still get the micros in there?
Thx in advance, the old geezer, :gw :D :D

Re: UV Sterilizer

Low flow rate is mainly to zap parasites, etc. You've heard correct that increasing the exposure time to UV will cause more harm...but in the case of green water, it will clear it up within a few days...just let it keep running. Oh, and by the ways, you might want to check on your dosing, water parameters, etc to get to the root cause of your GW...

Re: UV Sterilizer

Thx, dawg, appreciate the info. It's a new tank set-up, GW seems to always be part of it. I'll hook up the sterilizer through the Eheim. Good luck against Tech.:gw :D :D
