100,000 gal pool

[PoolDoc]

You're welcome.

Please note that I was NOT suggesting that you add it all at once; rather that 100# of dichlor was an appropriate quantity for your pool, and will allow you to raise your stabilizer in the process of chlorinating.

Per your email, you should vacuum up all that loose DE.

(BTW, please post online instead of emailing. Thanks!)

Oh, sorry about that. Here's the post:

Before the grids & manifold were replaced, it seems that the filter was blowing DE powder back into the pool. I'm guessing that's why it's still cloudy, that there's lots of DE powder in the pool. Although, I can see the step now in the deep end!

Per your email, you should vacuum up all that loose DE.

Does the DE powder settle to the bottom of the pool or is it suspended in the water causing the cloudy water?

[PoolDoc]

The DE settles, the dirt that was in the DE is likely suspended.

Yeah, there is finally FC!

1. Are you testing with the K2006?

2. What does your water LOOK like? (Please fill out this form: http://pool9.net/pf-hist-form/)

3. Can you verify that your pool has NO feeders or chemicals anywhere between the skimmer and the filter?

4. How much dichlor have you added?

Yes.

2. What does your water LOOK like? (Please fill out this form: http://pool9.net/pf-hist-form/)

Cloudy, light green

3. Can you verify that your pool has NO feeders or chemicals anywhere between the skimmer and the filter?

No feeders or chemicals between skimmer & filter..

4. How much dichlor have you added?

40#

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!

[4dks1]

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.
