Just got back from the pool store with a phosphate reading of

my other numbers are
FC 4.11
CC - 0
TC 4.11
CYA 35
alk 100
hardness 230

my options are to do nothing, as my water appears clear and no signs of algae. or I could throw in some
phos out, which involves the pool getting cloudy for 4 days and lots of vacumning etc.

skip it! Unless you level is way-super-higher than what was being discussed, someone (waterbear? JasonLion?) has said the high-phos angle is just the latest and greatest way for the pool store to separate your money from your wallet!

see the last post on this thread.

You may want to verify your Ph level. The pool store has it at 7.9 which is a little high...you could use one of the calculator programs to find out how much acid you need to bring it down.

I think I have the JasonLion calc linked in my signature...check it out>>>

Combining both posts above is the best advice I think you'll get. Ignore the phos and lower the pH to around 7.4

Thanks for the advice, I will bring down the pH today, just need to get to the backyard with the acid.
I do notice that this year my pool is taking a lot more acid than it did last year. Anyways, thanks for the advice. The pool
store did say I could just leave it alone as nothing may happen, so they are not completely trying to hose me.
