I put above 10 to see if maybe there was an ammonia problem that could be cleared.
My tests above were my OCLT and they showed that FC was dropping overnight.
Plus, 8 gallons to get above 10ppm suggests something is strange. It should have taken 2 1/2 gallons.
Problem solved. It occurred to me that the guy who opened the pool, may have mistakenly swapped the handles of the 2 Jandy valves I have. (The other, which I didn't share pic of, controls the return jets.) I took both handles off and sure enough, the one with the broken tab was on the wrong...
A few days ago, I was getting >0 CC readings and was trying to figure out what to do. So I took a step back, got my other numbers in order, and let the pool sit for a day. Did nothing.
So here's what I did yesterday. Water is crystal clear, BTW. And CCs went to zero went I let it go. (I...
Sorry. I meant Sodium Bisulfate.
New FAS/DPD test just now. Using exactly 1 heaping scoop and stirring/dropping fairly quickly.
FC - 3
CC - 11
Added 2 gallons of 12% chlorine that I bought last year, so likely reduced in potency. Will check again in 30.
When I do that, I get CC results over 10 and very lower FC numbers, which seem unreasonable is a spotless pool.
Another interesting note...
I followed up with an OTO chlorine test. After adding the yellow drops, and shaking a bit, it gave me a reading of about 3. I list it sit another...
I just got a batch of new chemicals. Trying to SLAM my pool. (CYA of 50, PH ~7.2, TA 150-160)
I woke up this morning and tested and saw that I was not at my target FC of 20. So added liquid chlorine and then tested 1 hour later.
4 test results:
FC of 15, CC of 1
FC of 12, CC of 4
FC of 5...
I had put a full gallon of 12% in this morning. At the FC is even lower than it was this morning. Current reading was ~4.5 for FC and a CC of 7 or 8. I'm going the wrong direction.
So I decided to SLAM the pool again, and try to keep FC at 20 to the CC drops...
Yes - CYA is staying at 50. My TA is too high at 200 because the pool opening company overdid it. I've been trying to drop it, but only started that yesterday. PH is around 7.4 as of this morning.
I had a few people swim in it the other day, but not for too long. That been it so far this...
I wish I could jump ahead one week to test/treat the pool without the added variable of all the pollen/tree floaters, etc. If a bit a swimmer sweat can raise CCs, I'd have to imagine this debris is NOT working in my favor.
Here's my piping:
The pipe at 10oclock is Skimmer 1...and can be shut off with the valve.
The pipe at 5o'clock is the main drain pipe...and can be shut off.
The pipe at 2o'clock is Skimmer...and CAN'T be shut off, and that pipe is behind that diverter valve.
Does that mean I would need to SLAM again? Or would keeping FC in the right range eventually remove the CCs?
It's certainly a possibility that my first OCLT wasn't done properly. After all, one of my chems was expired.
