PHOSfree - Not Working...What did I do wrong?

Hi all,

I am closing my pool for the first time on my own (used a couple different companies in the past, both which I wasn't happy with, so I decided to do it on my own) and while prepping the pool, I decided to remove some metal stains that in my deep section and have been annoying me all year. I haven't had the time to take care of them until now.

To get rid of the metal stains, I bought STAINfree (and am planning to use METALfree, followed by a Culator to remove the metal from the water). I noticed that STAINfree recommends the water having 100ppb or lower of phosphates, so I measured the phosphate level and found that it was 300. I then bought Pool Magic Spring & Fall PHOSfree and added around 1.7 liters of it (as my pool is around 34,000 gallons and it says that 1 liter removes 300ppb of phosphates from 20,000 gallons.

It's been a few days and the phosphate level is still reading around 300. I have a waterfall going down from my spa to my pool, and the water is forming bubbles (not the typical bubbling that would happen from the water impact). It's definitely related to the PHOSfree, as the pool never did that prior. I made sure that the water was balanced prior to adding the PHOSfree. I backwashed the filter the day before, and after adding the PHOSfree the pressure has only gone up a little (nowhere near the level that would indicate a backwash being needed).

My questions are:

- Does anyone have any ideas as to why the phosphate level didn't drop?
- Is the bubbling normal after application of PHOSfree, or does it indicate something's wrong?

Thanks so much for any info!

I would phone the company and hear information from the horses mouth. Phosphate lowering compounds (Lanthanum chloride) often cause clouding of the water for a while but not foaming in my experience. Propriety formulations may vary so back to the company for advice.

Most important is find the source of the metals (which metal?) and sort out that issue. sequestrants are only a temporary measure as chlorine breaks them down using more chlorine and buying more sequestrant etc etc.
