Hi, Steve.

What kind of chlorine (ingredients) did you use last year other than pucks? Do you have a CYA reading? That is going to be something we'll need to be able to give you very good advice. What all have you put in this year, meaning ingredients. Do you know what type of kit you have?

Re-post with the requested info and somebody here can try and help you get this figured out. Also, spend some time reading through a lot of the posts here on the forum and also on our sister website www.poolsolutions.com . Lots of good info for you to learn about taking care of your pool!
