Pool chemistry differences between gunite and fiberglass pools

[ddown]

Hello All:
We recently sold our home in CA (where we had a gunite pool/spa combo installed 3 years ago) and purchased a home in WA state with an in-ground fiberglass pool in good condition. I've always maintained our pool myself and was wondering about the differences in water chemistry needs between the two. What are the ideal parameters for fiberglass? Also, the new pool has a sand filter instead of cartridge and I was wondering how often, and how much, backwashing is required?

Thanks!

Welcome! For chemical levels, you'll want to refer to:

For your filter, we recommend a backwash once the filter pressure increases by 25% from the clean baseline pressure. You can slo read more about that on:
