I have to admit, sunny days make me happier.
But everything comes with a price they say, and sometimes the price you pay for ample sunlight is pond algae.
In the case of green water, which is caused by numerous single cell algae, the sun can play a major role in it’s growth.
After visiting with many pond owners over the years, when we get calls about green water, one of the common questions we’ll ask is, “does the pond get a lot of sun exposure?” The inevitable answer is almost always, “yes”. Other pond owners that had several ponds were often quick to point out that the ponds in some shade, were often clearer, and the pond’s in the sun were quite green.
Now don’t get me wrong, you want your pond to be exposed to a bit of sun…that’s just a good thing for desirable plants and your fish too, but too much of a good thing can often cause some problems.
