Phosphate testing

[CarlD]

I think he wants to know if $10 for a service to add phosphate remover is a good price or an indication they didn't use nearly enough. I think.....

If that's it, I can't answer.

It depends on the phosphate level of his fill water.

Thanks Carl & Doc. Carl had it right seemed like not enough may have been used. The water looks good and I took my test kit with me. Is there a test for phosphate in fill water?

[PoolDoc]

Yes, the Taylor kit is best. The AquaCheck test is cheaper and easier, but isn't very useful at PO4 levels above 500 (0.5 ppm). Water company samples may have 4,000 ppb (4 ppm).

You'll find the Taylor kit info toward the bottom of this page: http://pool9.net/tk/

PS. Even with the Taylor kit, you may have to dilute samples. If you do, buy a gallon of DISTILLED water from Walmart., to dilute with.
