That's DH for you! He specializes in doing things the hard way. LOL! He's very scientific about everything! To be fair, he says the bottle is an odd size, so it makes it hard to measure it. I think we'll find an old pitcher or something and make quart and/or pint markings on it and use it for adding bleach, so we can do it the easy way, but for now, he's still doing it the technical way.
Okay, I was at work today & DH did not test the FC levels this afternoon. They were 4.5 ppm this morning. We swam at around 11:30. At 9 p.m. this evening, the FC was only 0.5 ppm. DH figured the amount of bleach to add to get it back up to 10 ppm and added 2,280 gm (about 2.28 Liters) of bleach. He checked the FC levels again at 11:45 (to allow time for circulation, and our level did not get up to 10 ppm. It only got up to 8.5 ppm.

Stay tuned for tomorrow's edition of "As the Pool (prayerful does not) Turn (into Algae) Again." LOL!
