No. That store in McKinney has none in stock. In fact, no pool store within reasonable driving distance stocks the Orenda PR-10000. I've checked them all. I've not been able to find a reasonable online source either. All the online sellers fall into one or more of these categories:

1. Only sell the larger sizes.
2. Want to charge $15-25 to ship one pint.
3. Look really sketchy, like a 12-year-old built the website.

I don't understand why Amazon only sells the industrial size containers. Anyway, is there another product that you guys recommend, which I can actually get my hands on, preferably via Amazon? I was thinking about Kem-Tek. But PoolDoc had indicated that the Clorox product (which didn't work for me) is a re-labeled version of Kem-Tek. So I'm not sure that's a good option. There is a SeaKlear commercial phosphate remover which claims to remove 9000ppb per 10kgal for $43 and free shipping (1 qt). I think that makes it a better value than Orenda anyway, especially with free shipping, and almost same effectiveness. Any experience with this product?

Thanks!

I'm working on the third quart of Kem-Tek this summer and from my somewhat casual observation it removes less phosphate than the label indicates - very close to the label of the chlorox product. On the positive side, My's pool's phosphate level has been below 125ppb since early August and the mustard algae has not returned. It did reappear in late July when the phosphate level was about 250ppb.
