    Do I continue slamming & sunlight question

    Hello, more questions about slamming. FC was 10.5 yesterday morning. I left it alone since we were swimming throughout the day. Tested last night & it was down to 1.5-eek! So slamming we go. I added recommended amount per pool school & about 45 minutes later did my ONCL night reading which was FC 19 & CC .05. Well, this morning I sorta kinda forgot about getting out there early due to a comfy bed & sleeping later (for once) 10 year old. I tested it around 10 AM. It is sunny out but hazy, but the pool is in direct sun until late afternoon. My readings this AM were FC 12, CC 0. Water is clear. What say you guys?

    Could i have lost that much FC in 2-3 hours of sunlight or do I continue to slam.

    If I need to continue to slam do I test it hourly?

    TIA-am loving this method even though slamming seems to be taking longer than I figured it would!

    Keep slaming, but you already knew that.

    +1 what robdac said.

    I would say that you can slow down your test to 2-3 times daily and eventually twice daily until you ready yourself for the OCLT.
