What effect , if any, will it have on my water?
Can I just go all season without it?

What if my CYA is low?

If your CYA is low, you will have to be much more vigilant in keeping chlorine in the water. The sunlight during the day can consume a normal chlorine level in just a few hours with no CYA to protect it.
That depends on how low. It gets rather difficult to keep chlorine in the pool when CYA is below 30. The lower CYA goes the worse that gets. At low CYA levels you are wasting chlorine and risking getting algae, so it is much better to not let the CYA level get too low.
So what is the fastest way to get CYA back in your pool? I belive my CYA is ~20ppm. I threw a trichlor puck (or dichlor, not sure) into the pool but that could take a week or more. Is there a faster way?
Pucks are trichlor.
Dichlor is granular chlorine that contains CYA and it dissolves very fast, for every 10ppm of FC it raises your CYA by 9ppm.
YOu can buy CYA/Stabilizer separately and add enough to raise your level into range.

OK, I bought a 1lb bag of Leslie's Chlor Brite. How much CYA will be added w/ one bag? How much Chlorine? Taking into account my pool volume.

Chlor Brite is Dichlor, which contains CYA. You can use Jason's Pool Calculator (link in my sig) to calculate what effects it will have added to your pool.
See the "Effects of Adding Chems..." near the bottom of the calculator.
Cool. I never noticed that there. Great feature. Thanks. That will raise my CYA by 4 and FC by 4.8. That along with the floating trichlor puck should bring CYA to 30+ shortly. MY FC held steady over night (0.5ppm loss) but drops like a rock during the day. I guess that happens when your CYA is 20ppm.
Sorry for hijacking this thread, but at least I stayed on topic.

I'm not sure if anyone is still monitoring this post but, I have algae problems along with -30 cya. My Question is should i slam the pool 1st or just get the cya up first so that the pool holds the chlorine to kill the algae during the slamming process.
