I have this HTH cal hypo (shock and swim) that says it "won't overstabilize your pool". Could I use a bag of that every three days as a chlorinator when I don't have bleach? I don't have the room to store a lot of bleach.

So IF I need more CYA, do I put it in a sock in the skimmer, and how much at a time?
First of all, how much bleach you need to put in depends on your CYA level and the overall condition of your pool... i.e. if you are fighting a bloom, it will take more than it will if you have clean water that you're trying to maintain. Give us numbers for CYA, TC and CC, and that will help us tell you how much bleach to add.

You can use the cal hypo to chlorinate, but again you need to know how higher you CYA is to know how much to put in there....and CarlD has already told you that regular testing is the way to do this. You can't just dump in what you "think" it needs without either being very, very lucky or taking a huge chance on ruining your liner (and your pool water!).

When I add CYA, I usually just put it in the skimmer and let it dissolve in the skimmer. How much to add? Depends on your current CYA level (I know, I sound like a broken record) and what your target number is. Again....you have to test regularly to know how much of what your pool needs.
