(I have this post on TFP also)

I have Ben's test kit and am testing pH as I go.

I am netralizing now. I started with the jacizzi first, and did overshoot the pH. The water is now milky, so need to figure out the next step. Do I just filter this, pump it out and start over or something else?

I added one box of washing soda to the pool, and the pH is still very low, but it does seem to make a cloud where I added the washing soda.

Any suggestions are appreciated.
