Quick question. Say you were building this algae reactor, which the guy claims he built for 100 bucks. But you're pricing out the same cast acrylic tubing and it costs more than $85 a foot, putting the price of the tubes at hundreds of dollars. Is there a secret source of 3' long, 3.75 OD cast acrylic tubing? (By the way, it has to be cast acrylic. Not extruded.)

Nerdy-science-geek question: What kind of pressure am I looking for if I want to bust algae cell walls by sending a algae-concentrated liquid through a small aperture? I mean, behind the aperture, size of aperture, etc....knowing that the sudden reduction in pressure *should* bust things up. Any thoughts? Of course, I am wondering about doing this in terms of what I've read, and may experiment with in future, but don't have firsthand knowledge of. Thanks in advance!

Should I eat it filter: Can of Bumblebee whole baby clams. Dumped them into my chowder only to notice that they looked a bit green. Google indicates this might be algae in their tummies? Should I eat them? Chowder is currently simmering, but will be tossed if that is what I need to do.
