I think my problem is caused by hard water, but here are the details.

I recently opened my IG Pool (16x32). The water was clear. I tested the water and vound the Ph was low 6.6 or so. I added Ph Up (sodium carbonate) and the water turned cloudy with a whitish colour.

I am thinking of using a Floculating (Aluminum somthing or other) in the hope that the stuff will precipitate out so that I can vacuum it out.

What do you think?
