Take a look at the Alkalinity and calcium section, I believe the 'airation' method of lowering alk is stickied there, it involves acid., patience and persistence. You are slightly on the scaling side of the Langlier index, however Chem_geek says that you shouldn't be in the scaling area yet. The cloudyness may just be left over from the water you didn't drain from the pool, you might try taking the pH down to 7.2 and see if that helps. Hopefully you'll have clear water soon!
