Free Chlorine problem

[waterbear]

With that Frogger, I'd get one that tests for CTA, as well. It might be quite high.

CTA? I've missed that one. What is it?

Prolly a one-finger slip of CYA.

[waterbear]

yup, you're prolly right. The reference to tabs slipped right by me! (I will gladly accept any public humiliation that anyone would like to lay upon me for that one as I humble myself!)

Ok on the tabs , didn't realize that they can cause problems, I am testing with the same brand as always and still no pink at all. is it possible that the chlorine level is so high it will register on the chlorine tab and just bleaching out the free chlorine tab ? can't believe it can be this clear and not have free chlorine. this inline system is called frog and you insert this plastic cylinder that cost like 18.00 and is probably a rip off.

I will get a liquid test kit and check back.

Thanks !!

Yes that is the ionizer system that I was referring to. You might want to read this thread by PoolDoc (the forum's moderator) about such systems!

The chlorine tabs are trichlor which contains CYA (stabilzer) and constant use will elevate your stabilzier levels and require that you run higher free chlorine levels and shock levels as the CYA levels increase. This is why most of the people on this forum use bleach which is unstablized chlorine after adjusting their CYA to the level they want. For more info check out this thread!

As I stated previously, certain Free Clorine tests can bleach out with high levels of chlorine in the water. An FAS-DPD test is the only way to accuately measure free chlorine levels above about 10 ppm that is generally available to pool owners.
Hope this info is helpful to you!

Me again, I had my water testing at a pool place with a liquid test kit and they said my problem is my TDS is 3500 ppm and should be 1500 and that I
should replace some of the water til it is down to 1500 or lower, but my water is still crystal clear and the ph, alk, total chlorine is ok, just still no
free chlorine ?

Then I talked to the place that installed my pool and they say the TDS
is not high ?

I guess I'm having trouble understanding what the problem is....you said you have clear water, and your other parameters except for free chlorine are "ok". Could you please post some numbers from a drop-based kit test for TC, CC, pH, Alk, and CYA?
I think your water is probably fine, and that you were probably just bleaching out the test strips. HOwever, without numbers to look at, we're all just guessing.
