Welcome to our forum.
So far today I have put 3 tablespoons to reach 4-5ppm. When I first filled the tub we added 1 teaspoon to start. Don't think that was enough in the beginning. How do you tell if ozone is working?...by the bubbles?It just seems every time I open the top in the evening you get a weird smelling chlorine smell. Maybe it is just me.
tvaughn,The N2 and the Freshwater (Watkins) are both made by the same company. If you notice, on the gray one, it has the N2 logo. The difference is the gray one is made specifically for Watkins filter pipes. The yellow ones have to be modified to work!
I wouldn't use too much DiChlor either. The smell that you're getting could be one of many things.I put in about a tblspn every evening, AFTER I get out of the spa. Using too much DiChlor will discolor your pillows and leave a harsh smell when you open the cover. You will know the difference between the DiChlor odor and Ozone odor before too long.Just don't overdo it with chemicals, if you are using a N2 system, you still need to use a monopersulphate shock daily, maybe DiChlor once a week.Good Luck...
So what modification would be needed on the yellow ones?
I don't have to make any modifications to get the yellow ones to fit in my HS Landmark. The N2 comes with 2 'support' pieces that fit together then get connected to the N2 but I find if I just use one, the N2 is in the proper place in the filter. I have not gotten nearly as much foaming since I started using N2 and I fouond my dichlor usage was about half.
