cloudy water

[mzsmiff]

I filled out the pool chart and today my pH is reading 7.8 and our chlorine is 0 but we add bleach in the evening and it has been holding over night however i do need to get a stabilizer.

We used the muriatic acid to bring the ph down and that looks good but there is still that white substance on the bottom and when you distribute it it makes the water cloudy and opaque but when its settled on the bottom the water looks crystal clear. How do I get rid of it?

Thanks so much for your help thus far you have been a wealth of knowledge to me on pool chemistry!
