skimmer foam

[LuckyReefer]

So recently i’ve added an air line to my skimmer since all it has is a gate valve and it’s improved its skimming tremendously however i’m noticing throughout the night there’s a lot of excess foam in the collection cup and i’m not sure if that’s normal or not?

Looks dry skim but some people skim wet. If you want a wetter skim just increase your air flow a bit but its yours choice
But yes it's normal
