CSI

[ethany]

How do you test for CSI? Not even sure what it is......I have a fiberglass pool. Should I even be testing or be concerned with CSI?

PoolMath will calculate your CSI for you after enter all of your test results. Negative CSI is a measure of potential for etching in plaster pools (not a problem for vinyl or fiberglass) and positive CSI is a measure for potential to scale in all pools. More here, Pool School - Calcium Scaling
