Water is still hazy. I vacuumed the bottom again but only got about 1/2 teaspoon of white granules and a few specks of debris in an hour so if the chemical residues are now gone and the water is still hazy, it must be the high alk level?

FC is still orange (so high, same as this morning)
ph 7.5 (same as this morning)
TA/CA 250 (same as this morning)
