I am new to TFP, just converting over after I did a little digging into what this CYA number on my Leslie’s test results meant and why it kept going higher.
Everything is going great so far!
Does anyone know the formula for the “adjusted alkalinity” number Leslie’s lists on their tests?
Is it: alkalinity - (cya/3)?
Thanks! Just switching over to TFP so I don’t have my own test kit yet.
