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.

Mrs. Everichon is convinced that there is a law or principle (as in "Foo's Law") which describes the phenomenon wherein a pond can take weeks to become 50% covered in algae, but then the remaining 50% takes only a day. [more inside]
