Thanks everyone for the welcome.I used to work for a pool company that built inground swimming pools.That's all I done,was the construction part and none of the opening and maintaining part so this is new to me,the maintaining part.Right off I bought the 3 way test kit for chlorine/bromine & ph.Have had no trouble yet but with such a small pool,630 gallons,I know,mud puddle compared to some of the others,but I do want to keep it safe because it would break my heart if my little nephews got sick or something because of the pool.I usually keep to myself so you probably won't hear much out of me unless I need ya'lls help about something.Thanks again for the welcome.
