Welcome to our forum.
I've decided that N2 only works well for one tub full of water. If you change the water, you have to change the cartridge, even if it has only been a few weeks. The ions and minerals have to build up to be effective. If you can get your water to go 2 months, it's obviously more cost effective than if you change water every month. A new N2 kind of shoots a hole in the "water is the cheapest chemical" theory.BTW, I usually try to raise the free chlorine to 3 ppm after use. It's down to 0.5 within 12 hours.
.. And it's the death sentence for N2. After all the info and people's opinions that I read about N2, I gave it a try as my dealer included it and IMHO - it doesn't do squat!!!My son and I soaked on Wed night and put in 1 teaspoon of dichlor for 400 gallons - it's about 1.5 PPM and haven't soaked since. Opened the cover today and it was cloudy, put in dichlor/ MPS shock and clarifier and cleared it up in about 2 hours. If my cloudiness was from improper sanitation - what the heck was the N2 doing? NOTHINGIt's a WASTE of money! If I put 2 teaspoons in on Wed and didn't use it as I have before, I don't think it would have clouded up. As WSD says "Spare the dichlor and spoil the tub" (or something to that effect) - it's so true!OK folks - MY opinion is: take that money and invest it in another bottle of dichlor! Don't cheat yourself in having 1/2 teaspoon for 300 gallons and think it's doing anything.And BTW, because of the clarifier use ... I now have FOAM and I was doing so well too!
You are useing it incorrectly. Upon fill up, add 1 tablespoon of dichlor per 100 gallons, in your spa 3 Tbsp. BEFORE each use add 2 oz. potasiumperoximonopersulfate (spa shock, activate, renew etc...) to activate the N2. After heavy use small additiond of dichlor my be added. This purifier is not intended as a stand alone, it must be used in conjunction with an ozone water purifier. Try it this way and see what happens.
Vinny,Sounds like we are both trying the same methods. I wonder how I am going to make out a month from now. I never thought it would be this difficult. My pool is much easier, I just pay a guy to take care of it.
