combined chloramines

This is my first pool. I got my TFPro test kit last week, Today ran a full set of tests. Also had tested at 2 pool stores. One store did the drop tests - my results are pretty much consistent with theirs except CYA which they measured as 60 PPM. The other store's results were all over the place...

TL/DR; A) Does the Chlorine drop test water sample normally turn pink several minutes AFTER doing the FC and CC tests? B) Does a solar cover disrupt the SLAMing process? Details... A) Leslies says I have high CC but ... I am going to attempt my first SLAM for my pool after getting low FC 0.5...

Hello, First I want to say thanks to this community as it helped me maintain a crystal clear pool last year. I just opened the pool on Wednesday and it was a mess of dark green sludge. I measured my numbers with my test kit and the CyA was zero. I realize now I probably should have corrected...

I needed to SLAM my pool while opening--it had a green tinge and 0 FC. I used roughly the same amounts of chlorine to do it as I did the last time I SLAM-ed, forgetting that I added CYA since then and need way more chlorine than what I remembered to reach SLAM levels. I've already passed an...

In January, I bought a house that came with a hot tub (manufactured 2003). The previous owner said it had been sitting empty for a couple of years, but worked fine. Inside looked clean. Filled it up, balanced the water and starting around 3 weeks it was forming a chemical smell and by 6 weeks...

I have recently started a 3k gal endless pool in my basement. Water was added over 5 days from the municipal water supply. I finished filling it about 5 days ago. I also added about 13 cups of chlorine over the 5 days. My Taylor k-2005 kit was about 15 years old (it's a 2nd hand pool) and...

I just got my test kit and did the full battery (I think). Results: FC: 1.5 CC: .5 TA: 150 Ph: 8 CH: 1 CYA: 40 Pool: ~30k gallons, vinyl. I used pool math to calculate bleach addition, and addition of low n slo I still had. I have read the ABC’s of Pool Chemistry and most of the articles in...

TLDR; I started SLAM last night. ~80 CYA, started at 0.3 ppm Chlorine, 7.5 pH. Dumped 4 gallons of 10% bleach. After it was dark (about an hour after dumping) FC read 34 ppm, CC was 1 ppm. This morning before the sun was up, FC read 22 ppm, CC was 0.5ppm. What is going on here? My novice...

Bit of newbie here that has been testing and maintaining his own pool water with a K-2006C and pool match for over a year now without any significant issues or even any issues to note at all. I have read all of the documentation on the site in the past and did a bit of a refresher today, but I...

I've looked around this forum for a while, but this is my first post. The pool runs on bromine. The sun breaks down the bromine rapidly, so this morning I put 2 trichlor tablets in the chlorinator to try to use less chlorine bleach. My understanding is the chlorine activates the bromide. This...
