Re: [GSAS-Member] Algae control; Vitamin D

[John Ruhland <john@drruhland.com>]

Where do I get such a culture, and how would I do it simply? Anita had 
suggested adding a sump
tank. Could I put them in a breeder net right in the tank? Of course, 
my hope is the green water clears
when the nitrogen level goes up.

When one overfeeds, the nitrogen levels go up. Is that an OK way to 
increase the levels purposely?
Since the tank is cycled, I think production of toxic levels of ammonia 
are unlikely.
Thanks, John
