New Acid Neutralizer tank water issues

[Lukasny]

I just replaced my AN with brand new tank and valve. After bw and rr my water comes out cloudy almost white. Any ideas why is this happening?

Backwash again. And again if needed.

Also, check the bed expansion by shining a bright light through the unpainted tank during backwash in the dark. See how far the shadow rises (bed expansion).

After few backwashes it cleared up. Thank you
