Filling up pool for the 1st time


Well-known member
OK -- that is a normal loss of FC during a sunny day in summer. I assume you are not putting chlorine in the water at the same time with a SWCG or trichlor pucks.
yes, I have turned off the chlorine dispenser..... I am currently doing some experiment to check on the effect of the following scenarios to the pool chemicals:

1. sunlight on the pool (FC consumption)
2. swimmers in the pool (FC consumption)
3. dispenser/SWG setting and pump operation hr (FC production)
4. heavy downpour
5. anything else? 🤔

Feel like I am back to school chemistry class 😂. Hope that with all the above information, I will be able to dial in on the setting of the chlorine dispenser/SWG and predict the changes in pool chemistry.....
