Protein Skimmer Level of Bubbles for Most Effective Skimming

[Jeremy Lain]

Hello, I was wondering if someone could help me understand where the level of bubbles on a protein skimmer should stay consistently for a skimmer to be most effective while skimming? I will attach a picture.

Most skimmers recommend right in the middle of the cup, so between levels 2 and 3 in your picture.

Alright. Thank you for your reply.
