Well i did the trichlor test and nothing happened. Today i put a chewable vitamin c tablet on a spot and that spot was clean in about 30sec.
So i dont know what to use for the stains other than stuff at the pool store. Maby load the pool up with orange juice. Just kidding. And I also need to add cya so i dont know if i need to wait till i get the stains out to do that.
