    Question Tons of Algae and pH and CL seem off. Please help.

    I'm new to taking care of a pool. The algae has taken over, it's very green. The pH on the Pool Style test kit is showing between 7.8 - 8.2; the BR/CL level is 6.5 & 3.0. I've added shock and algaecide, per my local pool store's suggestions. Also brushing and vacuuming daily. Suggestions please? I'm just so frustrated.

    Time to start reading Pool School. Pool School - Pool School

    You will need a good test kit. Here is a comparison. TF-100 or Taylor K-2006
    Pool School - Test Kits Compared

    A SLAM will be in order. Pool School - SLAM - Shock Level And Maintain

    Until you get a test kit, add 1 gallon of bleach daily and continue to run pump and brush.

    Once you get the test kit, post a full set of numbers as described in this link and someone will reply to help you get the SLAM going.
