Okay, so I'm not sure what all the parts do. The foam riser (right hand side) is for what? Is that where the water exits and the foam topper-thing is used to eliminate extra bubbles?
And the intake is just the pump's intake, correct? The pump forces the water and bubbles into the skimmer (this must be a aspirating impeller skimmer, right?). The water exits up the foam riser because of the pump's pressure? So, by installing a gate valve on the riser, I should be able to affect the height (amount of) water in the skimmer (if it's running external). Am I on the right track?
I'm thinking out loud here, just need some advice, thnx. Anybody know of a good resource page about how external skimmers work?
