100,000 gal pool

[PoolDoc]

Add 15 pound doses of cal hypo THROUGH THE SKIMMER.

If you mix some DE in as you add the cal hypo, your filter won't stop up so quickly. But doing this will result in calcium depositing on the filter. You'll need to manually clean the filter at least every other time, even if you have a multiport valve.

Do NOT adjust your pH down, unless it goes above 8.0. It must 'float'. Doing it this way will prevent the cal hypo from adding extra calcium to the pool; it may even lower the calcium and/or alkalinity in your water.

Do NOT ever allow cal hypo and dichlor to come into direct contact with each other. They are fine, once they've been dissolved, but BAD things will happen if they touch each other as solids!

Added the 15 lbs of Cal hypo. Is this to be done until the water clears?

Thank you for the DE powder tip.

Keeping the Cal hypo & dichlor separated. I appreciate the warning.

[PoolDoc]

Yes.

But you need to understand that you can expect to loose 15 ppm of FC weekly -- on your pool that translates into 15 pounds of cal hypo weekly . . . when everything is perfect.

What parameters are we looking for to be able to swim in the pool? It is not clear at the bottom of the deep end yet.

It's looking so much better, thank you so much!

[PoolDoc]

Chlorine = to 10% of CYA level; pH between 7.0 and 8.0; no slime.

Also be concerned with cloudy water. If you can't see a swimmer on the bottom, you can't rescue him.

Ok, thanks.
