    Stains on steps

    Yes they are fiberglass. Sorry I always call them plastic. I am guessing that the pool is over 10yrs old, so would the blistering start to happen over a period of time, or is it something that happens when the pool is "just old"?

    Increase CYA in a swg pool

    Thank you to everyone who replied to this thread. i should have mentioned that, yes I do know that at the end of the day, it is still a chlorine pool, but just having got hold of the pool, i didn't want to upset the apple cart by telling her "Don't be stupid woman, it's still a chlorine pool"...
