Hello Folks

Received my new TFT 100 replacement chemicals.

My numbers are the following:

PH - 7.5
FC - 3.5
CC - 0
TA - 100
CH - 150
CYA - 0
Temp 87 degrees

I am concerned about my CYA, should I be?

Thanks in advance for the help.
Joe

Well, if you don't want your FC to overpower you in that indoor pool, yeah, you need some CYA.

I'd suggest about 30ppm (no more) to help buffer the chlorine. [FC/CYA][/FC/CYA]

Thanks, so I am sorry, what do I add to the pool to achieve you recommendations?

I am assuming some sort of stabilizer, do you have any recommendations? All I use in my pool is bleach.
thanks

Yup, you found the right product, Joe. You could also find it in cheaper granular form but to tell you the truth I'm kinda over that and have been using the liquid lately.

Yippie: I read this on this site: " CYA - Cyanuric Acid - Protects chlorine from sunlight and determines the required FC level. (outdoors 30 to 50, SWG 70 to 80, indoors 0 to 20)" Since I have an indoor 5000Gal endless pool, which is covered 98% if the time, should I shoot for 20? The FC at 3.0 does not overpower me. I will probably add a little to see where it ends up. As an ER doc, I have learned it is easier to ad a little than to give to much......
Thanks
again
Joe
