Problem

Hong Kong waters are dirty.

Question

How can we clean the dirty water by using biology? By clean we will be using the World Health Organisation's Guidelines for safe recreational water environments

level of intestinal enterococci per 100 ml

The level of toxic species of algae that occur in the marine environment

pH levels

E.coli levels

Methodology

We will test 5 marine species which are know for cleaning waterr
all at the same maturity and
the same amount of the species
the same water from one large tank will be divided into 5 other tanks where the water amount will be equal
equal amount of time will be given in this research
3 tanks of each species to get a good average
water quality
do we give breaks for the animla
are they okay to stay in the environmentn

Experiment, Measurements, Observation (biology)

The species: Sponges, sea cucumber, mussels, oysters and Cleaner Shrimp or barnacles

we will measure the levels of pH, E.coli, toxic species of algae and intestinal enterococci before we put the species in. And we will measure the same things again after a certin period of time

Conclusion

We will draw a conclusion by making a table comparing how the levels of pH, E.coli, toxic species of algae and intestinal enterococci changed in each tank after the species where added. And we will see which species got the closest to the WHO standards.
