Thread: New IG, first TF-100 readings; wait until filter is running?

    New IG, first TF-100 readings; wait until filter is running?

    Here are my first readings using the TF-100 test kit:

    Cl = 0 (I didn't measure FC or CC since Cl=0 with the K-1000)
    pH = 8.2 or greater
    TA = 240
    CH = 320
    CYA = 0

    Water was delivered into pool on Friday (2 days ago), today is Sunday, and my pump and filter should be running by tomorrow afternoon or Tuesday at the latest. A few questions:

    1. Should I wait until my pump is running before trying to correct levels?

    2. I believe my highest priority is getting FC up to 4-6, getting pH down to 7.5-7.8, getting CYA up to about 30. Lesser priority is getting TA down to 60-120 (that will come down naturally as I lower pH, right?). Lowest priority is getting CH down say 150-200 (vinyl liner).

    Any answers, suggestions, and advice are all welcome! First pool I've owned. Kids went swimming for 10 minutes yesterday even though temp is about 70 degF. Concrete deck should be poured tomorrow assuming no chance of rain.

    Yes, wait until your pump is running and then make adjustments.

    Your priorities are also right on the money. It would also be a good idea to put a large jug of bleach in the pool if your pump is not running tomorrow evening.

    Just pour it in slowly and stir it around with a boat paddle or something. As long as you stir it a bit, it'll spread pretty evenly in a short period.

    Thanks for the help. BTW, sorry for the sideways picture - I'm clearly not only new to owning a pool but new to posting pics on TFP!
