Just got a spa, and loving it so far. I was thinking about daily maintenance... our manufactures guidelines says to add 13.5g chlorine granules (mixed with warm water) every day. Would it be safe to pre mix and store 7 500ml bottles of mixed chlorine? Then treatment would be as simple as empty a bottle into the tub daily.
Additionally, can anyone recommend a reasonably priced chlorine tester solution... if such a thing exists?
