*SIGH* Looks Like I Have da' Mustard

Hmmm... Very non-specific ;-)

Nope, not specific. Specific leads to chasing numbers which leads to over-adjusting which leads to running to the pool store for someone to "Tell me what to do!". That's not best for you. take it easy. Move a little at a time. Set targets and sneak up on them.

Well... As y'all predicted, I am now beginning to see signs of bleaching of my liner. Sooo... I supposed it's time to let it come down. I hope I am not too late. We got a 15-year liner about 4 years ago, but I would bet the warranty won't cover this. Oh well. On the brightside, it looks like the algae is gone. "So I got THAT going for me... Which is nice."

Warranties don't cover bleaching.

But bleaching is pretty literally just 'skin-deep', and doesn't affect the functional longevity of the liner. (Personally I'd prefer a white liner: blue makes pools in Georgia hot, and white pool walls make the water look more 'blue' when the water is in really good condition.)

Well, after five days, the Kem-Tek did virtually nothing to lower my phosphates. It's still at, or near 1000 :-( I have just added another dose (1 quart) and we will see what happens. I wonder if the high FC reduces its effect. Nothing on the label addresses it.

How are you testing? With the Aqua-Chek, or the Taylor? ( I scanned back very quickly, but didn't see)

The reason I'm asking is that I found the Aqua Check and the Taylor matched fairly well below 1 ppm, but not above. At 1 ppm or higher, the AquaCheck made no distinctions -- with samples with 1 ppm and 3 ppm PO4 appearing identical to me.

If you're using the Aqua Check, you need to dilute your test samples to results of 0.5 PO4 or less, and then multiple back. (Mix 1/4 cup fill water with 3/4 cup distilled water, test, then multiple x4).

I don't know what to say.

Go ahead and retest -- as carefully as you can -- your pool water, now.

Then test again after 5 or 6 days. Be sure to run your filter most of the time.

. . . just had another thought. Do the DE test on your filter: http://pool9.net/de-test/ If the filter doesn't trap the phosphates, they won't be removed.
