That makes me feel better. What is the lowest level it would be safe to swim in (just in case) and where kind I find that information for the future?
. I can do both. [emoji5] As soon as I saw your first post I immediately went and added the chlorine I had on hand (1 full gallon and about a quart in another jug) and sent my hubby to the store to pick up 5 more gallons to have on hand. I will keep my FC above 6! I promise. [emoji5]I will suggest once more that if you intend to have your party day after tomorrow, understanding your SWG is not your priority.
You need some chlorine in your pool RIGHT NOW.
Perhaps in your time reading here at TFPs you missed folks advise new pool owners that its best to add the salt to the water and wait a day or two before turning on the SWG. Your first post here seems to imply that your PB did it all in one step. I wonder if that might have affected the SWG in some way?
What was your FC level before they started up the SWG? As others have said above, a SWG is best thought of a device to maintain your FC as it works so slowly.
I wonder if because your FC was low to begin with, if you're not experiencing a nascent algae bloom?
Can you perform an Overnight Chlorine Loss Test (with the SWG off) to determine if you're losing FC to organics? Overnight Chlorine Loss Test
