GMU:Life in an aquatic ecosystem/Preclass

From Medien Wiki

Last semester students in the class Winning natural habitats have designed a pond. Since the pond was leaking some water, we have decided to redesign it while taking the upper layer of the pond away and replacing it with a 5cm layer of sand+bentonite mix, 7:1 mix. On the top layer we have still added some soil, partially mixed with bentonite.
