Will 6ppm FC destroy my plaster finish

[macman]

I just recently had our pool resurfaced and the cya level is 30ppm. It is a SWG pool. Currently it has 6ppm chlorine. Will this cause the finish to bleach or etch over time?

From what others have said regarding swimmer safety, it sounds like 6ppm FC is fine but not sure about it in terms of preserving plaster

Welcome to the forum!
That level of FC is very safe for people and pool surfaces.

I suggest you read ABC's of Pool Water Chemistry.

Thanks, that’s what I had assumed.
What about during the night or cold season? Wouldn’t the FC be less bound to CYA in the absence of UV rays, thus more effective and therefore more corrosive?

Chlorine is bound to the CYA regardless of UV or temperature.

Maintain the FC based on FC/CYA Levels
