I have used it quite a bit with good results......BUT i dont get where you can make 30 gals of bleach out of it, or 15.
It does say MAKES UP TO 30 GALLONS, but they mean UP TO 30 gallons of cleaning solution, not concentrate.
I mix it 1:2.5 (1 jug into 5 gal bucket and fill bucket with water)
It works better than just bleach alone and you dont need to add any soap to it. It is not the most economical but it is easy to mix and effective.
dont run it through your pump.
