Long time pool owner first time BBB.. The pool is Clear, Clean and in Balance.... Now for the daily maintenance! I have been using a puck feeder for years now must add Cl manually, When is the best time to check and Add. I was guessing in the AM, Is that correct? I will also be using the feeder at a low level(2-3) when not available on a weekend to add Cl manually to keep it from dropping to 0. I am using the pool calc target numbers!

I usually add chlorine in the evening. That way, the FC is at its highest overnight when the least amount of loss to UV rays occurs.
