Re: Aquatic Plants Digest V1 #290

Earle Hamilton has set up two tanks with undergravel filters + laterite 
dust, and in about 1 week the water cleared almost entirely, and after 4 
weeks it was crystal clear.  One of these two tanks is currently running, 
it is his experimental tank with 1/2 side laterite + undergravel filter, 
the other 1/2 side laterite + undergravel heater.  He's trying to see if 
there will be a difference in plant growth between the two sides.
