Doing absorbic acid treatment today and don’t have access to Polyquat 60. I know poor planning. Is there another algicide I can use?

The reason I’m asking is I live in a small town and nobody sells the polyquat. Treating iron stains

What is your plan after adding the ascorbic acid? To rid the pool of iron, you really need to drain it. With a vinyl liner pool, you can do partial drains. and that might work to lower the iron content.
Best to just work quickly (the AA is pretty instantaneous) than add algaecide if you can.

I was gonna do the AA treatment, then add a sequestering agent. I already did a half drain because CYA was too high. Can I use any algicide? I read the article and it recommended polyquat 60. I’m following the instructions for an article in trouble free pool on AA treatment.
I did and they didn’t have the polyquat 60 I was just wondering if there any other brands that are trustworthy

Polyquat is best as it does not consume the FC as quickly.
Just stay away from a copper based algaecide. The Ammonium ones are OK, just realize your FC will be consumed quickly until you eat up the ammonia.

OK. I’ve got the free chlorine very low per the article on trouble free pool. Just wanted to prevent algae why I got the chlorine so low.

Correct. If you use the Ammonium based algaecide that is available at Walmart near you, it will do that. But as you add chlorine to consume the AA it will also be effected by the Ammonium. So it will take a steady stream of small amounts of liquid chlorine to get back to an acceptable FC level after the treatment. It will also likely show up as an elevated CC level for awhile.
