Perfect pool, but phosphates were high - no one using currently, should I bother reducing?

I don't understand the magnetic attraction of the pool store.

Hahaha, I don't go unless I need something I can't find elsewhere cheaper, for example had to buy muriatic acid at leslies which is when I had them test my water to compare to my numbers. I test my water on my own but this is first time testing phosphors

Sometimes I want to match up an O-ring and I don't care it's $3 more. Or a similar few bucks keeps me from having to go across town to Walmart for salt. There's no Wal-Martians at the pool store, AND its much closer.

When my cheapo pole broke, I went and told them I wanted one of the ones their service people use. It was a $100 aluminum pole (probably $200 now) but it's 9 years old and going strong.

You can get great deals on equipment if the right rebates are going on, and you'll have local service if it has problems.

They're not inherently evil. Its just that their testing is rubbish and they don't even know what they don't even know about chemistry.

Not sure why everyone here claims pool stores are not accurate. I went because of memorial day sale and got mine tested. It's very similar to the numbers I get. It's easier to test in my house though.

Browse some threads & you will see why it isn't accurate.

*They* claim it. I only see all their claims. Over and over and over and over. Stick around and browse, you'll see it too.

Can I SLAM with 87 CYA?

Hello! Readings today: FC: .66 CC: 1.11 pH: 7.9 TA: 78 CH: 323 CYA: 87 CYA was 130 yesterday, I drained about 50% and refilled, targeting 55-60 CYA, ended up at 87. I reallllly don’t want to repeat that process but to SLAM pool math says bring FC to 34ppm. That seems VERY aggressive… can I tone...

The funny thing, is that with most tests we see, they get 80% of it close enough. But it's always a different value that's off. Today it's CYA and tomorrow it's CH. (Etc etc). It calls all of the testing into question because we don't know which ones are close enough today. In the case of the post I linked, we would have had him drain half his pool if we listened to the pool store test. That's a pretty big oops.

I know this is a hit dated but just found the paper. Phosphates per Leslie's was 1157.

My test was 1000, maybe higher but less than 2000.

So seems they were fairly accurate on this test.

Phosphates per Leslie's was 1157.

I love how they claim to measure down to a precision of 1 ppb.

Yes, super accuracy!
