  • UV Sterilizer

    So I have a 24 watt green killing machine UV Sterilizer... my pH has ALWAYS been 7.6pH...ALWAYS... only thing different that I added is a 24 watt UV Sterilizer and tested my water... my pH is now 6.8pH....

    Errrr could the UV Sterilizer effect pH... I just have never thought about it...

    I don't think so.
    How long is always? When is the last time you tested it at 7.6 in this tank?

    Eta: I'd also check gh and kh.

      Do you have well water or town water? If it is town water, they might have changed something and that affected your pH.

          Then you wouldn't think it would change, but if something happened in the ground upriver from you, it might affect the water quality.

                C.H.U.D - no, but seriously, even though the river is underground, something could have happened to affect the quality of the water. Whether it's construction, septic systems, or whatever. You never know.

                  Running mine 24/7 hasn't had any affect on the pH, but I don't know if it is possible or not. Here's an article that has tons of info on UV sterilizers and a section on its effect on minerals in the water, it may help unless you already came across it. http://www.americanaquariumproducts....ilization.html I read it a few months ago, but I can't really recall much from it .

                    Your location could be playing a role. As Lori was alluding too, even ground water is likely to be influenced by surface water, influence really can go either direction depending on the aquifer's depth and zone of recharge. As spring rolls in, runoff can change water quality. Here in the Rockies it's really pronounced. Hardness and alkalinity drop at what I would say is a significant amount as the melt water begins to influence the river flow. As a matter of fact I've started to notice some slight drops in alkalinity in some of the river samples I've been doing at work.

                          If your dealing in heavy snow melt you could be having a pH issue, they are right it will be influenced by ground water, easy way to tell is to check your pH at the tap. If that isnt the issue then I would begin to run the usual barage of tests on the tank and ensure that everything is as you expect to find.
