    Issue with CYA levels

    Cyanuric acid heated up and dissolved almost immediately

    My pool went neglected for a few weeks as our first child was born last month (I added bleach/acid sporadically but not with any precision). Now I have a bit more time to get everything balanced. My pH was about 8.5, FC 0, and CYA was almost 0 which was a surprise since I had added about 4lbs...

    CYA on a SWG Pool during SLAM

    Hello Everyone. Long time member but mostly a reader. I am very late into the opening of my pool this year. I have a SWG pool and I got my CYA up to 30. I am wondering about the need to have it in the 70's now since my SWG is shutoff until I am done with the SLAM process. Is it necessary to...

    Sweet spot in the CYA to Chlorine table?

    I am aware of how stabilizer works with your sanitizer, but I was wondering what you should actually keep it at. Higher CYA means higher Chlorine demand but less burning off, Lower CYA means lower Chlorine demand but more burnt off by the sun. We all know that. But in your opinion, what would...

    Vinyl pool..above ground cya and chlorine

    I am getting differing info everywhere. I have an AG pool with vinyl liner. Cya is at 30 using call hypo as main sanitizer. Question is..the pool math calculator says to keep fc btw 2 and 6 at 30cya. All websites seem to recommend keeping fc btw 1 and 2.5 for vinyl liners to keep them in good...

    CYA confusion... (Pool store vs. Taylor K-2006)

    Alright, I installed my new (to me) 24'x42" above ground pool last summer. Had no idea what we were doing so we pushed the 'easy' button and went to Leslie's. Spent several hundred bucks on chemicals last summer and thought there had to be a better way. Talking to a co-worker, I became convinced...

    Salt, Cyanuric Acid and Pool Proof

    I have a vinyl lined, 12,000 gal salt pool. I run the filter and chlorine generator 24/7. I added Pool Proof (borate harmonizer) which claims it will cut down your sanitizer usage, make your ph and alk levels play nice, etc. my question is, With the borate harmonizer doing what it is suppose...

    Draining pool to reduce CYA, replacing water, then SLAMing

    Hi. My CYA is off-the-charts high, so I'm about to drain the pool, replace the water, and then start the SLAMing process. I have read the SLAM article. Just to confirm I understand the correct order of re-introducing the chemicals, I need to bring the pH up to 7.2 - 7.5 with the new water...

    CYA sock method?

    Can you use a skimmer sock for the CYA sock method? Or does it have to be a regular sock? (Skimmer socks are a lot thinner in material and am worried about adding to much CYA at once)

    NO CYA

    Hello Forum! I opened my pool Monday and it was greener than previous years. So I began my SLAM. I SLAM'D it based on my reading from the end of the year for CYA levels, which were around 30. So I SLAM'd at about 16 for FC. However, I tested my CYA levels and it's reading zero. The pool is...

    CYA and pool draining

    Hi friendly, informative pool people! Newbie here going through my first CYA battle...and the CYA is winning. Initially my readings were 100+ (so who knows exactly what the ppm was). So, I drained about 13 inches down about 6 times now over the last 3 days; I've heard too many fiberglass shell...

    First Water Test - Now Taylor 2006C

    Hi everyone, I ordered this test kit before I joined here and started reading the advice. Should I scrap it completely and order the recommended Taylor? Or can I use this kit on most days and the more expansive testing 1 or 2 times per week? Here are the result I got: FC 0.6 CC 0.0 Bromine...

    CYA - cure is worse than disease?

    We're closing on a house with a pool that a pool company has maintained for about a year. The pool company has just informed us that the CYA levels are much too high and are locked, and we need to drain the pool completely, pressure the sides of the pool and refill to (hopefully) allow us to get...

    Pool opening numbers...recommendations?

    Hi guys! Just took my first readings for the season, trying to get this bad boy opened so I can get the solar cover on and start warming that water. Here are my numbers. I didn't do pH because usually you have to adjust TA first, so pH doesn't matter much. FC: 0 CC: 0 TC: 0 CH: 50 ppm TA...
