shauna...welcome to TFP!...as PaulR mentions...you probably need to add some stabilizer/conditioner (aka CYA) to slow your chlorine burn rate when using liquid chlorine....we don;t like pucks, but as FPM mentions they can work if you understand what they do to you water chemistry...over the long term they are acidic and will overstabilize your pool.
My advice
1st...Read Pool School - button on upper right of this page
2nd ...Re-Read Pool School
3rd ...I strongly suggest getting a good test kit...we recommend two...the TF100 from TFTESTKITS.net or the Taylor k2006
If you post some test results for us, we can help guide you to slow down that FC burn rate or give advice on using that chlorinator.
These days I would much rather invest in the intex (cheap) swg (Krystalclear)...and I know i'm biased since I own one, but I paid $180 for mine and it has been over a month now of no pucks, no bleach bottles...coupled with some advice from this awesome forum (people like FPM and PaulR

) and my water has been crystal clear. Try out what we call BBB and I promise you will not be disappointed.
