I would do a water change too start with ..till you find out possible cause ...have you been dosing anything ....vodka ...vinegar .....anything like that ..?

No dosing, i have been battling gha which i found being due to bad rodi water. Last water change was a week ago. When i got home from work last night my sump had gotten low due to a semi clogged up baffle and the return pump was flowing water and bubbles, which happens time to time, but this time it was like foamy on the top of the water.

I don’t run filter socks on the normal, should i add one in for a day or two?
