cya testing

How much liquid chlorine do you add per day? I’m in DFW area with about a 20k gallon pebble tech pool. The pool is mostly in direct sun but it gets a good amount of shade starting around 3 pm this time of year. I have been using tabs and watching my CYA closely, it is now at 40-50 so I’m...

Since receiving my test kit I have never gotten that little black dot to disappear. Last summer, I put in 4 lbs in the sock at the beginning of the season and dissolved but the water balanced and didn’t have any algae issues so I didn’t worry about it. This season, I dissolved 4 lbs again over...

I use bleach and a Taylor kit for my pool. It is 24 feet around. The pool is clear. The CYA was 5 when I opened the pool. I added 3.5 pounds of stabilizer. I like to keep my cya at 40. My pool gets direct sunlight all day. My Taylor kit is reading the CYA at 30. My local pool store, which just...

These were all taken from the same distance and then cropped. For such a subjective test, thought I’d post these images to see which CYA level the forum would assign.

I’ve tested via liquid my CYA and have never seen anything below 100. I so wish there was a more definitive test like counting drops. I’ve also tested using two different strips and they both come back 50. I tested the strips with tap water and they correctly showed “0”. Which should I trust...

Since my pool was filled (December 2019) I have been gradually raising the CYA. The pool guy started out with chlorine pucks when it was too cold for the SWG to run. After startup was complete, I began adding solid CYA a couple of pounds at a time using the sock method. I am up to a total of...

Hello! I am a new pool owner here in the hot AZ desert and have been doing my own maintenance with good results so far. We filled the 9000 gallon pool in early July and so far about 16 Tri-Chlor pucks and maybe 5-6 bags of the 13oz shock have been added. I took a sample to my local pool supply...

Hello I have recently purchased the Taylor Technologies K-2006 test kit and ran some tests on my pool water. The results came back as follows: CYA: less than 30 ppm FC: 0.2 ppm PH: 7.8 TA: 60 ppm Calcium hardness: 70 ppm Having read through some of the threads on this forum I came to the...

Looking for some help on the proper way to test my CYA with my T 2006. I've seen a few posts here about looking for the black dot while holding it at your waist level as you as standing up. I've literally been working everyday since opening my pool and have had no time to read the...
