My Taylor K-2006 arrived today. 1st test results are as follows
FC: 2.8 ppm
CC: 0.2 ppm
PH: 7.9 ppm
TA: 130 ppm
CH: 270 ppm
CYA: 150ppm? (Wasn't even halfway up to the "100" mark
What sequence should I start fixing things that are out of line?
Also open to recommendations on good products to use?
Thanks in advance.
Sandra is correct, you need to do a diluted CYA test. 100 is the limit of the CYA test, so you have to do a diluted test. While the full instructions are in the Pool School, here is the short version. Mix 50% pool water with 50% tap water. Use this mixed sample as your test water. If still at a 100 you will need to dilute more. Here is a great chart by JamesW to explain dilution rates and what you multiply the results by to get an approximation of your CYA level.

Your chlorine is extremly low fo ryour CYA level. Our
normal FC/CYA chart only goes to 100 CYA, but using the math behind it can be computed.
.... "Min FC" is 7.5% of the CYA level
.... "Target FC" is 11.5% of the CYA level
For now I would bring the FC up to at least 15 as a minimum. The rest of your numbers are not that bad and can be dealt with later.
You ask "Also open to recommendations on good products to use?". How about products not to use. The Chlorine Tab Feeder you are using is what is driving your CYA too high. A good portion of every tab is CYA. You have to stop using it and switch to liquid chlorine products that do not add CYA.
How much
