Intex Ultra Frame 18 x 48 Pool

That isn't CYA. It is Dichlor which is chlorine with CYA in it.

Test your pH again this evening before you add more dichlor. If your pH is above 7.3 or so, don't add Borax.

Here are my current readings:
Cl-5
Br-10
pH-7.5
Alk-200
Hard-90
How should I proceed this evening ?
Thanks
I have not added salt yet. I didn't test CYA because my understanding is that it takes a few days.

You can ignore the bromine side of your tester; this is a chlorine pool.

Your OTO chlorine tester can only read up to 5ppm of chlorine. Use the color chart at this link to see what you think the reading actually is:>

According to that chart I think it would be between 6 & 9 best I can remember. I check it this afternoon before coming to work. It was pretty close to the 5 may have been a little darker than the 5. Any advice on what I should do tonight.

[Watermom]

I think you are fine tonight.

Ok it's been 6 days since initial fill. I started the SWCG yesterday. I took samples before it started for today. Here are my readings:
Cl 1-2
pH 8.8
Alk 140
Hard 40
CYA Black dot not disappearing with full tube.
Any advice on how to proceed.
Thanks

You need to check your SWCG manual and see what the requirement is for the CYA and raise it to that level for your unit to function properly.

Your pH is way too high. Use some muriatic acid to lower it some. Please read this first:> http://pool9.net/muriatic/

A dose of dichlor would help CYA correct ?

[Watermom]

Yes. For every 10ppm of chlorine that dichlor adds, it also increases the CYA by about 9ppm.
