Hows the flow?

Do I need more or less surf? Looks prety good to me. it's been running a few hours. I have magic surf and the newer 2x surf from lava lab on hand and distilled water. If I add more I get more very tiny bubbles when it stretches and breaks appart with less the main blobs are a bit large. I would like to stop those micro bubbles and keep a good mix of blob sizes if possible.
