The Algae Problem.

I found out a few solutions for the algae problem:
1. Add in prawns as they eat algae( very SLOW!!)
2. Add a sucking fish( if possible i donate mine)
3. Add in air pump/Filter(need electicity)
4. Use chemical( Able to buy from fish shop)
5. Add a UV light sterilliser( Very EXPENSIVE! And need electicity!)
6. Add covering to block direct sunlight

Algae growth need 3 key factors:
1. Strong sunlight(we have that)
2. Lots of Food like fish poo, thus creating ammonia( food for algae)
3. Carbon dioxide(the pond does not have enough oxygen)

Hope this would help............
