    Welcome. Now that you are here you are on your way to taking control of your pool.

    I know you have already spent a ton on pool store potions, but in order to properly manage you pool you will need one of the recommended test kits if you don't have one already. TF-100 is the best value, especially since you have to SLAM.

    One of the main tenets we teach here is understanding the CYA/FC relationship. Since you have been using so much granular shock, and were probably using pucks before that, it is likely that your CYA is off the charts. This will mean draining and replacing water to bring CYA level down. Getting CYA under control is critical because with super high CYA, the levels of FC required to clear your pool will be astronomical.

    We really can't give any recommendations without a full set of test results (preferably from one of the recommended test kits since pool store testing is so unreliable)
