    Pool test results

    13,500 gallon pool, plaster with DE filter system, bleach, no spa
    Using TF-100 test kit.

    TC=3
    CH=200
    TA=190
    CYA=45
    PH=8+
    CL/BR=1-2

    Pool math says add the following

    41oz. bleach
    33 oz. muratic acid
    200 oz. calcium chloride dihydrate (what is this?)

    Pool is crystal clear with no visible algae.

    Do I need to add all of this all at once?

    Did you do the FAS-DPD chlorine test with the powder? It gives FC and CC directly which is much more useful than TC.

    You certainly need to get the pH back down in the 7s.

    You also need to maintain adequate FC. According to the FC/CYA Chart, for your CYA level, the FC should NEVER be below 4ppm ... so you should likely target around 7ppm every day.

    Your CH is also a little on the low side for a plaster pool. Depending on where Lake Jackson is (Add the state please), if you have high evaporation and hard water, this could raise by itself in a few months. If not, you may want to bump it up to about 250ppm with the calcium chloride.

    Get the acid and chlorine in the pool ASAP. Let the water circulate for a few minutes between the addition of these 2. You can verify the levels after the water circulates for 30-60 minutes.

    Re: Pool test results

    How much Pool School have you read? Start with these:
    ABCs of Water Chemistry
    Recommended Pool Chemicals
    How to Chlorinate Your Pool

    I seems like you need to learn some more about the chemistry so that you understand the information that the test kit is providing you. Also PoolMath is just a "dumb" calculator. It can not tell you how to fix your pool. It only will tell you what chemicals to add to achieve the target numbers YOU enter. You have to understand the chemistry to know what target to enter and why.
