We had our spa for a bit over a month and we still cannot keep our water clean.
We started off with Chlorine based sanitizer (came with the startup kit), where we had to add a table spoon a day. Didn't work well, the water would be really cloudy when used multiple times a day. We were tired of chlorine not working out, so we went to Bromine tablets in the floater 2 weeks ago. Chlorine always tested 0 to 0.5 during the 4 weeks we used it (Tested at the dealer and with strips), and pH was high (8 and wouldn't do down even with pH-).
The new Bromine floater is open to the max, we see 6 tables in the floater. However, the bromine still tested between 1 and 1.5. When we shock the spa the water clears after 24 hours but return to dull and cloudy the next day. We have to shock again to make it clean.
Alkalinity is at 100ppm, pH is between 7.6 and 7.8 (depending on the day tested), Hardness is 200ppm.
We cleaned the filter every week with water and a hose. They are clean, we didn't use any filter cleaner yet, wanted to fix the water problem before adding even more chemical to the mix!
The spa foams a lot as well, I am sure it is related.
The shock we use is unstabilized chlorine. We also used chlorine free shock, but found the chlorine based one worked better.
My question, is what are we doing wrong so that we have to shock every other day? The water is not smelly, or green or anything, just cloudy (not much, but enough). We had very good help from our dealer, testing the water and recommending chemicals to balance it, but I am looking for another opinion here to see what to do. I don't want to drain the spa and be faced with the same problem in a week.
The spa filters twice a day for 4 hours each time. It has an ozonator that I am assuming is working, hadn't tested it yet... Testing the ozonator is our next step if you cannot fix the problem soon. We use the spa around 60 minutes a day, most of the time we are with kids, which make us 4 people in total.
Yes, I almost forgot, we used "Spa Perfect" every week since we had it. Not 100% sure it works but it seems to help on occasion.
