    Sorry, W-M.

    That was the sort of simul-post that you get when you start an answer, run some errands, and then finish it without re-checking the thread.

    The chlorine level was 5.0 ( probably higher because the yellow was dark but definitely not orange). The ph level looked between 7.2--7.8.. I am happy things look better but confused how they were so high this morning and are now almost back to normal. Thanks again!!

    This chart may be help you decipher those high chlorine readings since they are higher than your OTO tester can differentiate:

    Pools with low CYA lose chlorine pretty fast. Continue to use dichlor for a little while longer until your CYA is around 50. Then you'll want to switch to just using bleach otherwise your CYA will get too high. (Don't test CYA too often or you'll use up all your testing reagent.)
