I followed the steps but when I fill the ciliner I can still clearly see the black dot at waist level. It's fresh water 24hrs old. I used the calc to add cya in a knee high.

Vandal said:The PB got the pool up to levels, I assume, and then dumped in the salt and started it up. I haven't been able to get a reading on CYA yet. Is there another kit I get from the store that is more accurate than the black-dot method just to get a second opinion, so to speak?

CYA is stabilizer. You added it, which you needed, according to the pool calculator, right? So you should be good yes? Otherwise I'm totally confused....![]()
The disappearing dot test is pretty much standard in home kits and pool store labs. Some pool stores use a colorimeter/turbidimeter to read the cloudiness of the sample but it really isn't that much more accurate.frustratedpoolmom said:Vandal said:The PB got the pool up to levels, I assume, and then dumped in the salt and started it up.

Nah, the home kits are all about the same. You could take it to the pool store and see what result they get?
Try this:tfnyla7713 said:So what is the trick to this test? Do you pour slowly till it first disappears, register that point or do you wait till the water settles and see if the dot shows. Watch out for that reflection of your head against the sky - can look just like a dot, make you crazy!!!!!
