nannochloropsis phytoplankton culture (questions)

[rayjay]

I forget how long FAF says it's good for, I think 4 months.
However, I've had some for six months with no problem.
Lighting looks just fine if those lamps are 80w or higher output each.
(8 ft strip?)
Are those 1g US or Imperial measure, or possibly 4L glass jars?
They are great for nurseries for raising reidi seahorse fry if they are.
Where did you get them?
As for cleaning the screen, I guess it depends on what material it's made of.
I have nylon and cloth types. The cloth I put in bleach water for about 10 minutes and then rinse well, the nylon one I put in vinegar for 10 minutes, rinse, put in bleach a couple of minutes, and then rinse well.
