Next morning... it's like I swapped out the tank water for air... It's "there's nothing there" clear. I could prop up a book on one end of the tank and read it through the 4 foot water column It's. Crystal. Clear.
Three weeks and a bunch of tests to keep an eye on parameters later, I've decided this UV clarifier is never getting turned off. Call me sold.
It's like the difference between SD and HDTV, I had no idea what I was missing before I added UV.
I finally upgraded to a "real" UV.
I'm all for saving money where it makes sense, but the possibilities of leaks and bulb/quartz/transformer issues made me go with AquaUV.
