The green water is free floating single cell algae and is caused by plenty of light combined with plenty of nutrients in the water. It's really impossible to completely prevent in a pond, but you can limit it by carefully monitoring your feeding and be sure to not over feed. As this is a small pond, water changes will remove much of the initial nutrient level. Be sure to remove any debris from the bottom as well, that a major source of the nutrients the algae needs.
There are chemicals that will kill it, but it will only come back in a short time and the chemicals are really bad on the fish. I would highly recommend against using any chemicals to clear the algae problem.

the greenish water that you are getting is simply algae formations. Go to your local pet stor are buy some treatment for this. It shouldn't cost too much and it shall help keep your pond less high maintenance (you wont be changing the water all the time as you appear to be doing now!)

the green covering you have on the top of your pond sounds like algae which is a type of plant, which thrives in sunny conditions. Potentially harmless although it can be known to limit the oxygen levels in the water. The best thing to do is either skim it off the top or buy some oxygenating plants to revive the water.

Id get some live plants to use up the nutrients that the algae is feeding on and feed your fish a bit less

This is an algae bloom. Happens every spring and sometimes fall.
The best article I've seen on this is posted below.

there are many factors of getting green water:
excess nutrients in the aquarium water
high ammonia and/or nitrate levels
light intensity and duration of light (or sunlight)
use of fertilizer/co2
stagnant (still) water (no circulation)

Add an anti algea/fungus additive for your pond water.

I have to agree with Magic Man on this one (lol).
