First results of test kit

Hi all:

My first test results:

FC 14
CC .5
TC 6
pH 7.5
Alk 150
Cal 300
Cya 100
Temp 74

38,000 galls white plaster inground in N Va.

Appreciate your comments...

Welcome to the forum!

How does your water look? Your chlorine readings aren't quite right. FC + CC always = TC. Test those numbers again. PH, alk, and cal readings are fine. Your cya is really high at 100. I suspect you have probably been using trichlor pucks to chlorinate with? You have two choices. You can either do a partial drain to lower your cya level or you can live with it that high, but you'll have to run higher than normal chlorine levels as a result or else you're gonna have algae problems. I would suggest just using bleach as your source of chlorine as it will not make your cya climb. Take a look at the following link. Repost after you recheck chlorine levels and also tell us exactly what all you have used in this pool.

Hi again:

Ok - 10 days after my first set of readings (been travelling) the results are:

FC 10
CC 0
TC 6
pH 7.5
Alk 120
Cal 300
Cya 100
I'll leave the Trych pucks for a while and just use bleach....

OK. Those numbers look better except remember that FC + CC = TC. So, your TC would be 10. Good idea to go with bleach. Everything else looks fine.
