You really can't do it too often. You just need to give the chlorine time to circulate.
Well, I didn't mean every 10 to 15 minutes around the clock, just initially to see if the bleach is doing what it should by checking FC shortly after addition. Putting in 3 1/2 gallons of 8.25, and being at 2.5 FC an hour later sounds unusual.
How do you know the bleach is new? Did you check the date code on it? Some stores have been known to sell old/weak bleach. I didn't mean you had done anything wrong in handling the bleach, but we don't know what the people who sold it to you did...

Have your FC numbers gotten up higher than 2.5 on later readings? Up to goal of 20 ppm yet?
Mikaklis, how much Ascorbic Acid did you use three weeks ago when you treated for staining? I ask because without a kit or TFP, you may have been flying blind
The advice you're getting here is for a SLAM, and with such low FC you likely need it because early stages of algae outbreak do indeed make water cloudy...but if your report is correct and you lost 18 ppm in an hour yet your pool is blue, I want you to know that its possible the Ascorbic acid is fighting the chlorine. I am hopeful that the sequestrant will hold throughout and you don't get more staining, because slamming does oxidize metals in the water.
I know you said you're not on well, but the fact that you've had to do what sounds like two stain treatments (which worked) suggests to me that you do in fact have metal, despite the pool store report that you don't. The purple flash point in your calcium test also suggests metals.
This situation is a bit tough to diagnose correctly from afar. So please tell us your readings and time between them so we can help out and keep an eye if you need to change direction a bit.
I'd also like to know how much calcium you had in the pool, if any, before you started using the metal sequestrant, and specifically what brand of metal sequestrant you used this season.
Sometimes the two types fight each other (eg if you used hedp an EDTA).
My metal sequestrant, metal magic, will bond with excess calcium and remove it...and the mfg says to in some cases expect cloudy water for a few days as this process is occurring. But that normally last only 2-3 days, not 3 weeks.
At any rate, do keep us posted, and cheers to clear! You are well-positioned to get control of that pool now!
How soon after your bleach addition did you measure the 6.5?No, not up to 20 goal. Questions. I woke up this morning and my FC was again at 1.0. I put in 4 more bottles (484 oz) of bleach this morning. That makes something like 16 or 18 so far and of course, right after I put it in the FC goes up to 6.5 (last night) but seems it keeps going right back down by the time I am ready to dump more in. Should I be testing the FC before or after I put the bleach in (this morning I only tested before I put in, not after? I maybe shouldn't measure right after I put it in? If it doesn't come to 20 right after I put in should I keep pouring more in until it gets to 20? I am off to the store to buy more bleach.
Sorry, I edited my message to Swampwoman but I guess I did it wrong because it does not look like it posted. Here is what I wrote:
I only took all the test measurements as soon as I got my TK100 kit in. Haven't taken anything but the FC test since because I thought I should concentrate only on the SLAM process at this time. Do you think I should take all measurements now and post? Not sure of what my CH was before putting in the sequestrant. It was "Metal Control" from Leslie's Pool Supply. The sequestrant was something I put in the 3rd time I added absorbic acid because the first 2 times the staining started coming back and I was unaware that I should be putting a sequestrant until someone told me that I needed to; and it did work, because I have not yet gotten any of the staining back so far. And I got my some of my bleach from Walmart, some from Dollar General and a few from Rouse's.
Could I just ask to double check - did you use 10 ml sample size and count 14 drops to make the pink go away (most recent FC test)?
You may want to retest after adding about 30 minutes after you put the chlorine in. (If possible)
