Is Polyquat essential?

Kinda depends where you live. (Hint: fill out your profile! ) Down here in Houston, TX, generally I start needing it when the water temps get into the high 80's and 90's. Even with keeping my CYA in the 40's, and keeping my Cl in the 4 range constantly (SWC) I still need it to fight mustard.

Thanks to you both.

I'm in Wilmington, Delaware (added to profile ).

I think I'll go without for now and see how things go later in the summer when the water gets very warm. Adding some for insurance while the water is warmer than normal would certainly be better (cheaper) than doing it for the whole season.

I might even skip it at closing this year to see how that goes. If this year is any indication, I'll start champing at the bit to remove the cover around now so I should be able to get the chlorine level up before algae is a concern.

Hi, Lenny,

I have never used it. So far, so good (3 years)

Absolutely. Using it now is really not needed. I only use it when my normal methods don't keep the mustard down.

You don't need Polyquat for your normal pool maintenance. Diligent daily testing and correcting your water will work brilliantly.

But, saying that, it DOES help if you let your FC drop due to sunshine, you take a trip and rely on someone else, etc. I like to add about an ounce and a half every week. That way, a 32 oz bottle goes for the whole summer. Since I watch for it to go on sale, and never pay more than $12 to $15/quart, I see it as cheap insurance. At closing, another quart and that's it for the season--$24-$30 more.

Do be aware that after you add PolyQuat, you FC level will drop and you'll need to add chlorine a day or two after. It's especially pronounced when you add a whole quart at closing. At that time, I wait 48 hours (during which time the FC drops), then push my FC up to shock level (15ppm in my case) and close it.

PolyQuat is insurance, no more, no less. You don't need it, but it doesn't hurt and CAN help.
