Clear waters

After an electrical storm, the water in my father's small fish pond is crystal clear, having previously been full of green algae. Similarly, my parents' drinking water comes straight from a nearby reservoir and often contains organic matter, but a storm also appears to clean it up. What could cause this?Michelle, Johannesburg, South Africa(Image: enrika79, stock.xchng)

I#39;m sure that some of these knowledgable chemical equations are probably correct, but I should also imagine that it#39;s something to do with the addition of pure, clean fresh water (ie rain) into a the pond which, if it#39;s anything like mine, is largely filled with stagnant, high ammonium amp; high nutrient-content water. The crummy water in the pond encourages algae etc whereas the fresh water doesn#39;t have the crummyness and represses it for a bit.Sigh, unil a day or two later when the blanketweek comes back :)

I'd imagine the influx of water containing high levels of dissolved oxygen, having fallen through the air, would stimulate the activity, growth and reproduction of animal life in the pond. This would then feed on the plant algae, clearing the green colour from the water.

How about this:the pond got more water(overflow).got the ozone.and got lots of oxigen by the drops hitting the surface of the water...like they have in the ponds...with a pump.

The algae in my pond when closely examined is full of tiny trapped bubbles.Thus, it floats. If you agitate it, the bubbles are released, and it sinks.Works for me.
