Calcium hardness and phosphates

[mcastellani]

Hi all,
Second year with a a pool. Comfortable using the tf100 tests. Thanks to this forum!!
I just want to confirm. With a Vinyl pool should I be worried about a low hardness level? It’s at 85. Second. Had pool water tested talking about high phosphates. They say 500 ppm. Is this something I need to be concerned about?
Fc 10
Cc 0
Alk 100
Stab 60
Ph 7.4

Nope and nope. Low CH does not matter in vinyl pools and if you maintain adequate FC for your CYA the amount of phosphates does not matter.
