yeah... I'll try almost anything once if I think it might help...I wish we had a bass pond(except for the mosquitos, of which there are about 5 or six all summer!)...I'd have crappie guts and seaweed for my compost pile! there's kelp down at the ocean, but it'd take a hell of a lot of water to wash out the salt. if I'm not mistaken, dried algae comes back to life in water...is that why you'd cook it?...I have noticed where I dump the varmint water buckets(slime green), the plants love it.
