I copied this from the Alkalinity and Calcium Thread (2nd Sticky):

Why does CA matter?
CA is the portion of the TA that is due to "carbonates" from sodium bicarbonate (baking soda), sodium carbonate (soda ash), and other sources. On pools with concrete or limestone surfaces, low CA together with low pH will let your pool water DISSOLVE your pool surfaces, which is usually NOT a good thing. If your CA is high, your pool will tend to cloud up, any time you add calcium hypochlorite or raise the pH.


If your pool is not cloudy, I would not worry. I don't know anything about calcium building up on the plaster, but if it is something you can live with, maybe you can do a partial drain when season is over and let it refill with rain water.

With your CYA at that level you have, you will need to run you pool with higher chlorine levels to get proper chlorination.

Chlorine level should be 8ppm to 15 ppm. Shock to 25 ppm

Now one thing with higher CYA is that the chlorine added tends to be used up at a slower rate. You may have to chlorinate maybe once or twice a week. You will have to check and see how it goes.

Good Luck!

Flicker,

Now one thing with higher CYA is that the chlorine added tends to be used up at a slower rate. You may have to chlorinate maybe once or twice a week. You will have to check and see how it goes.

Well, not really. Most folks on this forum have to add chlorine more frequently than once per week. The consumption of chlorine is dictated by organics introduced into the pool.

Secondly, the Sun will destroy chlorine if it is not protected with CYA so, in some repects, that would mean the Cl does get consumed at a slower rate but it seems a little misleading to think you may only have to replenish weekly or bi-weekly.
