It wont' work.
The way it works is this:
WHen sunlight hits the barley, it begins to break down due to a certain
kind of bacteria. It produces minute quantities of H2O2 -- peroxide.
This kills of algae. I'm not sure how the "extracts" work, or if they do.
But, I assume they simply break down into peroxide as well.
So, the short skinny is: If it doesn't get sunlight (artifical light
doesn't work) it doesn't work. Thats why people who hide it under
waterfalls, etc., dont' have any success. Peat moss does the same thing,
but when used to soften water in aquarium, has no affect on aglae.
