Greetings from a new (one week today) tubber!
We have a 5 person 470 gallon hot tub with an ozonator.
I have been using the test strips and no matter what I do I can't get my Free Chlorine level to register. I tested last night after we got out - (2 bathers, but we are heavy users, maybe total of 3 person hours a night) and found that my overall chlorine (CF) I think it is - is high, and no FC showed up so I put in 2 TSP of the non-chlorine shock that came with the tub, I ran the low jet for 15 minutes then put the cover on and went to bed. I also noticed a white water line while I was in it yesterday - I used a washcloth (that I didn't run through a rinse cycle first D'oh! - and wiped the surface down.)
I have read the main topics here - and maybe need to read them again because I don't really understand them yet. I ordered and got a Taylor drip test kit yesterday, I read the booklet that came with that - but I'm still a little confused and have not yet used it. I plan to this weekend when I can take my time and do it right.
Is there a thread here that talks about how to use a Taylor kit? I've never owned a spa, and don't know anyone who currently owns a spa except for our neighbors and they have to my knowledge never changed the water - I've never seen them test and they don't seem to use it.
So far, the water appears clear, and feels good - but we are getting some foam, not bad - but I don't like it. I used a little bit of foam remover but that does not seem to have helped.
The chemicals I have are the starter kit - they include:
Is there anything else that I should get or need?
I have read that ozonators use up chlorine - but our dealer told us that would help us to use less chlorine and not more.
My husband has a skin condition associated with Lupus, and has gotten a tub rash once before when we used a tub in a cabin we rented. I am in charge of the water, he only agreed to the Hot Tub if I agreed to manage it - and want to make sure I do this right.
Any help would be much appreciated!
