I've never used any start up chemicals? Maybe that's part of the issue? They gave me Jump Start and other stuff.. but I never put it in. I have a HUGE bucket of hockey pucks and a bucket of CYA and some Borax left. Oh.. and some soda ash. Plus the Jump start, the Black Algae Out and some bottles of winterizing chemicals they gave us with the pool.

What is DiChlor?

=======================

We bought the pool last year and there was a massive issue because the installers ripped the liner. After a year of back/forth they gave us a new liner this year.. but the pool was mostly empty from last autumn until May. I didn't have any collapse problems.. but now I'm worried. Maybe I should cover and then empty and refill when we get closer to swim season next year?
