First post, just want to say this board has been great. Just found it earlier this year, so this is the first year I will be taking control of my own pool instead of being "pool stored." Been going great so far, I purchased the TF-100(great kit ) been doing my own tests which have matched up pretty good to the pool stores test. I just wanted to double check myself.
I've had a problem with mustard algae for the past 3 yrs in a row. This year I want to get rid of it once and for all. So far I have been following the shock procedure for 4 days now and the water is crystal clear. My FC levels are still dropping, so I am going to continue the process. Just wanting to know if I should go ahead and bring the FC level to the mustard algae level now since my water is clear, or wait until the FC level holds overnight? Right now I am losing about 1ppm/hr with the SWG running at 80%. I do still get a couple of spots coming back, they are more white to gray in color than before. Vacuuming them up at least once a day. Could this still be algae that is consuming the FC even though the water is so clear?
Latest test results
brought Ph down to 7.2 before bringing FC up, not sure what it is now(didn't think it would be accurate)
Sorry it's so long, just wanted to give as much info as possible. Questions in blue to make it easier. Pics attached, algae spot, deed end to show clarity of water, and overall pool.
