HELP - High TA ph CH

[eddman]

Opened pool up major algae. 0 TC, pH - 7.8, TA - 170. CYA <10.

So i looked here and did a super shock with about 8 gals of 6% bleach then ran filter for 18 hours, retested FC about 5 still green tinge so added 16oz calcium hypo - 73%. Ran filter 18 hours more.

Algae hasd disappeared but now I am getting the following readings:
TC < 1
pH 7.9
TA 220
CH 360
CYA < 5

Additionally, the pol is cloudy and some sort of clearish scum floating on the top.

Advise?
