Nice work, looks like the fuge has a lot growing in it already. How much flow are you getting via the overflow?
Thank you, I'm only getting about 10 gph tops I'd say, about as much as 3 air line tubes could syphon. This is due to the fact that I went with the smallest pvc pipes they make, and have a very small height difference between the overflow and outflow to the refugium. It's fine for what I'm doing but wouldn't try to reuse it if I went to a 10 gallon or anything.
