    Teach me your chemistry!

    Ok, so I'm ditching the pool store and I'm going to need your help! My pool looks amazing after you all helped me through a nasty algae issue. I had the water tested assuming it would be perfect because it just looks SO pretty! Unfortunately, it isn't and they (of course) suggested that I purchase 4 different products to balance it. I know my first step is to purchase my own tester. Can y'all recommend one that is accurate and decently priced? Ok, for the chemistry...... here are the readings they came up with. I just did a huge dose of chlorine to kill the algae so why am I back down to zero?

    Easy, here is the kit you want. Do not confuse cost with value. This is the best value out there for a test kit

    TFTestkits.net

    The chlorine question is easy, your pool consumes chlorine every day. You have to add it every day.

    The teaching is above this post under the link to Pool School.

    Whoa, you add chlorine every day?! Wow! So then I need to just figure out the alkalinity and CYA issues. Ok, off to pool school I go!

    Re: Teach me your chemistry!

    Many of us have been in your shoes and you are making the best decision imaginable to test and maintain your own pool. I was ignorant of basic principles allowing the pool store to misguide me. With TFP, and my TF-100 test kit, my pool is crystal and requires very little effort to maintain. As you go through the TFP site and/or the links below in my sig, you'll begin to understand why it works....and what the pool stores do NOT tell you.

    Oh, and don't forget to update your "signature" located under you profile settings with your pool information. That comes-in quite handy. Welcome!

    Yup, to steal Richards line, a pool is like a pet - you have to feed it every day, even on days you don't want play with it.

    Yes, between bathers and sun, you will have to add chlorine frequently. Initially, it will likely be everyday. At this moment, you must add some or you are going to be fighting algae again. Use Pool School to figure out how much. Once you get it under control and start to understand the chemistry, you might be able to go two days but you will have to check it everyday. There are ways to add liquid chlorine of you desire but that is probably a bit in the future.

    BTW, according to their test your TA (total alkalinity) is perfect. Don't listen to their recommendations.

    That is assuming their test is correct, which it often is not.

    Re: Teach me your chemistry!

    Here is the first lesson.
    1. Dont listen to the pool store. Their adivce and testing is horrible.
    2. Get your own test kit and test the water yourself.

    While you are learning the chemistry (it takes a while to soak it all up), use these following 'tools' to maintain your water parameters. You will needing these from now on, so book mark them or print them out for quick reference.
