What are you using to test your water? You said in an above post that the last time you tested for CYA at home it was 55, but state that it's now zero. Unless you totally drained and refilled it since the 55, then that's not possible...the only way to reduce the CYA is to either let the pool go completely green or drain and refill 100% of the pool all at one time.

Stabilizer is the same as CYA, and I suspect that's what they labeled as "UV Shield". Look at the container. If it says the main ingredient is cyanuric acid or isocyanuric acid, then it's CYA. If the container lists any additional or different ingredient, then please post that here, because it may effect what you have to do to clear it up.

Having a zero hardness is not the cause of the milky water, and certainly does not cause the foam. I think that the combination of lots of additions all at one time and the phosaway stuff you added are the problem. The only thing I know to do at this point is to keep your chlorine levels up (and if your CYA is really 55, then Cl of 1 ppm isn't going to be high enough) and keep your pump running.

Also, if your alk is 150, do not add any washing powder, because it's going to go too high. You can use Borax to raise the pH if you want that any higher, but personally, I'd leave it alone. Continuing to add stuff to the mix is going to make the problems worse instead of better. To answer your question about the chart, no, there's not one that I know of that will tell you about r washing soda calculations. There is a bleach calculator around the forum that has Borax amounts listed as a calcuation, but that's not for pH control, it's for the use of Borates, which isn't something that you need to worry about for right now. Won't do you any good for pH control issues. At 7.3, I'd leave it alone.
