Part of my problem (i think) is I'm getting my phoshates checked at the

low 100s.

Two weeks ago I had my water tested. *She tells Phosphates are at

A week later I took a sample in and she tells me the Phonates are at
"300". *"Last week you said they were at 1000."

Here reply: "I don't know what you did but it came down."

I'll be buying my own test kit ($82.00) for a pro testing kit. I can
learn to use them, instead of relying on "free testing". I'll also by
phosphates remover from another brand name --- not the diluted
solutions this store sells and hypes.

Very good advice about the test kit. I don't trust the kids at the
pool store either. Listening to them you could spend hundreds
of dollars buying their Balance Pak 2000 or whatever instead of
a cheap readily available chemical like baking soda.

I use the Taylor 2006 test kit, which is about $50. It tests for
everything you need to measure including cyanuric acid and
free chlorine. It's probably saved me $1000 compared to
taking water in to the pool store. And the pool has been
trouble free.

I agree with Steve that if he's putting in a lot of chlorine
he may be lacking stabilizer. Key question, what form is
the chlorine that's being used? If it's liquid, there is no
stabilizer. If he's using trichlor, then that includes stabilizer.
You don't want to get too much, because once it's in
the only way to get it out is to drain the water.
