If you feel you must use phosphate remover, don't buy the stuff from the pool shop - what is in it? It's sodium hydroxide, about 2%. And it costs the earth.
Instead buy Draino or similar product which is sodium hydroxide 95 - 100% and costs almost nothing from the supermarket.
You need to calculate very carefully how much you should use by comparing the dosage rate of the pool shop expensive stuff and working out how much to use of your Draino or similar.
It'll be a very small amount indeed (about a desertspoon roughly - but CAREFULLY calculate it out for yourself).
And if you can't do the calculation, don't use it.

Hi Robert, just wanted to follow up and thank u for all your advice!!
I came to you with my milky, cloudy, phospate invested pool. Its been a few weeks and I am happy to report my pool is back to normal!!
I followed your directions step by step and basically it only took me about 60.00 in shock and acid to see the bottom of my pool again!!
You are a genius!
I bought myself a good testing kit and dont rely on the professional pool store folks that got me in this situation in the first place.
