The new kit arrived from TF Test Kits, and the results are in:
FC: 5 ppm
CC: 1 ppm
TC: 6 ppm
I'm running an Aqua-Rite SWG in a 10K gallon fiberglass pool. The pool is always covered on weekdays, unless the kids get in, and generally open all day on weekends. I'm also recovering from a major algae bloom last week. The water is nearly cleared up... but not quite. It's still a liiiiiiittle bit cloudy white.
I read the article on this site about SWG levels, and have considering (for now) to target FC around 6, pH of 7.5, T/A of 80, CH of 250, and holding CYA at 80. I put these targets in the pool calculator, which calls for aeration to lower the T/A, 21 oz of bleach to raise the FC, and 5 1/2 pounds of calcium chloride. So, I'm thinking I follow the aeration procedures first, and then adding the calcium chloride (assuming I can find de-icer at this time fo year!).
I have a few questions:
1) should I add the bleach to reach my target FC, even though I'm running the SWG? What is the theory on shocking with a SWG?
2) since I'm fighting the algae bloom, I'm running the system 24/7, with the SWG running 33% -- which is WAY more than I've had to run it in the past to maintain decent FC. I'd like to get back to running it 10 - 12 hours soon...
3) My SWG and salt test strips do not agree at all on how much salt is in my water. The strips show a concentration of almost 3500 ppm, while the reading on the SWG says 2900. It shut down on me last week (leading to the algae bloom, I believe), when it read the concentration at 2700 ppm. Over the last week, I've seen the SWG readout go as low as 2800, and as high as 3100. Water temp has been 81 - 85 degrees all week.
Also, I had dangerously low pH last week... which lead me to add two boxes of borax. I'm feeling better about things, and am anxious to get back to crystal clear! Thanks for any advice.
