Your sorta "past this" now, but one thing you should never really do is worry about much of anything until your CYA is dialed in. Dumping gallons of liquid chlorine in a pool with sky high levels of CYA is just wasting chlorine. Any sort of adjustments, especially when faced with or in the...

I typically keep my CYA right at 30 PPM. I close my pool right around the time the leaves start falling here in PA. I don't open it until around the start of June as the nights here just get too cold, even with a solar cover on it, to have it be very swimmable before then. This will be my 7th...

Is the information on this page no longer accurate? https://www.troublefreepool.com/blog/2019/01/18/chlorine-cya-chart/ On the SWG page, it lists 60 PPM as the minimum for target level..... it also indicates there's a tiny fluctuation in necessary chlorine for SWG pools. For example, at 60...

As others have mentioned, the CYA test doesn't need to be super critical. The key is to have it above 20 PPM and below 80 PPM. I have a fresh water pool, that I manually chlorinate with cal hypo 73 powder. So I keep my CYA around 30 PPM. FOR YOU - since you have a salt water generator... your...

The bonding just grounds the pool to the pump, to whatever the pump is grounded too. I'm no electrician, but if the pump is wired to a grounded line then the ground path to your breaker box, and then outside to the grounding rods driven into the ground are "good enough". Sounds like the idea...

I don't know the exact chemical composition of both products in question, and i'm not even a shade tree chemist... so I can't attest to how "safe" things are offically... but here's my take on it. The sanitized tablets contain CYA (cynauric acid) known as stabilizer. The unsantitized tablets do...

CYA of 100 is just wayyy too high for a manual chlorinated pool, it's even a touch too high for a pool with a salt water generator. You need to chop that in half, which usually means draining half the pool, and replacing half the water with tap water effectively reducing the CYA by 50%. It's my...

I do also highly recommend the TF-100 pool kit. It's 72$ but let me tell you, it's worth every penny. I bought my kit I wanna say at the start of the 2017 season, and bought a refill of the reagents in 2019. I will say up front, they do not recommend using the reagents past 1-2 years... but I...

Using the handy pool math calculator, you can be fairly trusting in the math vs the test... although the test is recommended, I'd be personally willing to trust the numbers until the testing materials came in. For example. If I have a 3500 gallon pool, and assuming I start out with 0 CYA from...

I tend to take a bit of a mathematical approach to my CYA. CYA only gets into my pool in the form of powdered stabilizer as I only chlorinate with bleach or cal-hypo. I can trust the test "well enough" to be accurate to a delta of +/- 10 ppm and I normally shoot for between 20 and 30. As long...

You can use the pucks until your CYA hits a suitable range. I keep mine between 20-40, people in brighter sunnier areas where their pool gets higher heat and longer exposure to the sun usually keep their CYA levels a bit higher. Google FC CYA chart and you'll find a nice little chart showing...

Not necessarily. The thing to fixate on is passing the OCLT. You want to have the pool lose basically no chlorine over night. You expect that even a healthy pool is losing chlorine during the day. But a healthy pool shouldn't use much if any chlorine over night. I have only had to fight an...

People are quick to take up arms and pitchforks when they hear you are using the pool store. Pool stores aren't known for giving great, reliable, accurate results. The TF-100 kit is. Having said that, it's a little unfair to paint every pool store owner as ignorant, deceitful and unreliable...

Interesting... I plan to stock up (not on this brand, but another similar product) if I can find it locally.... I was going to buy what amounts to 3 months worth (as my swim season isn't much longer than that). So I can plan on the stuff being just under 10% by the time my 3 months is up (or...

I'm not sure what CA is supposed to be... CYA or in other words stabilizer? If your using pucks, realize your adding stabilizer to the water with each and every puck. Before long, the CYA will be so high that the chlorine will not be able to have much if any of an effect on the pool. You need...

You might not want to hear this but...... I recommend you drain the pool completely and refill it. It's going to take a long time to fill that pool with your every day garden hose, so you may want to ask around at the local fire departments what they might charge you to bring in a tanker of...

It can take several days to two weeks to get the pool cleared up, as long as you wind up with a clear pool and you keep the chemical levels where they should be, there is no reason to panic or worry. Just stay the course, you'll get there. I assume, although you don't say it, your using a...

There's a Weis Markets very close to where I live. If they have 12.5% at 2.62 a gallon I'll probably buy as much as I can (ideally 20 gallons) as that would likely last me most if not all of the swim season.

Welcome! Glad to see your pool is headed in the right direction. At times new folks can be quite a bit intimidated by the overwhelming response in tossing the pool store aside, buying a TF-100 and doing your own testing. While I generally agree that doing your own testing is generally the way...

Make sure you check the percentage on the bottle as well.... I found our local dollar store to be selling stuff that's even sub 6% and IIRC it wasn't even a full gallon. The funny part about Wal-Mart is that they usually carry the Pool Life chlorinating liquid which IIRC is 10% and they carry...

My pump was off though when I just went back out.... the reset tripped on the outlet. I don't know if the outlet is bad, or if the pump itself is kicking it. Maybe because the skimmer overflowed and showered the pump with water? I don't know.... it sat outside all season long last year and got...

Results of my first test (30 min after adding CYA, and 2 gallons of 12.5% liquid chlorine) using my trust TF-100 test kit. Also note: this is a test using the original kit I bought two full years ago, so its been used for two seasons and this inital test of this third season. Even though some...

I'd imagine what really happened is that with CYA being 0, you were likely left with a lot of water that didn't have good circulation and / or the chlorine didn't mix well. I'd chalk it up to a pool not being properly filtered / pumped and the chlorine / CYA levels not being proper. I'd suspect...

I think the most valuable part of using multiple stores is the expectation that you will get some largely different results, and realize that "most" pool store tests are full of bologna. A real testing kit like the TF-100 used by someone versed in it is the best way to get accurate results :)

I've found that I've had enough reagents in just one kit that I was able to test fairly often over the course of two full swim seasons. Having said this, the people who sell the kit (and myself as well) recommend you replace the reagents every year to be on the safe side. Once I got into the...

You can use calcium hyopchlorite if your calcium hardness isn't too high. Easier to put lots of chlorine in all at once and cheaper BUT you are adding hardness to the water each time. Not a problem, unless you use it for years... then hardness can start to become a problem. But while you are...

May seem a bit biased, but I believe the TF-100 kit is the kit to beat. One kit lasted me two seasons, although they do recommend you replace the reagents each year for a reasonable price... they discount the refill kits right around spring time.

I wouldn't trust the pool store numbers. I'd at least get results from one if not two more pool stores. Ideally, Id buy the TF-100 kit and do the tests yourself. Once you get the hang of using the kit, which is not difficult, you will get much more consistent and reliable results. IF your...

My guess is that your using tri chlor hockey pucks in your pool or some other form of chlorine that contains stabilizer in it (CYA) You probably just got lucky and kept getting fairly consistent results. A hot, sunny environment will consume CYA. My environment isn't even all that hot or sunny...

For what it's worth my original TF-100 kit was used for two seasons, and this season coming up will be the third I've had that set of reagents. For the first two years they worked great. I imagine, but am not trusting, that they might still even work well this year... but I sprung for the refill...
