Oysterfeast causing overflow to gurgle

[Chameleon]

Has anyone noticed after adding oysterfeast there sump gurgles where the overflow return comes in? I have always wondered about this and am wondering why it does that. Thank

Do you turn off any equipment when you feed the oysterfeast? It could be tosses your skimmer into overdrive. Just a thought.

no not the skimmer it is definitely the gurgle of the overflow sump return that is affected. Everything I leave on
