Was wondering if someone could tell me why i have algae growing only
where the water returns into the pond.It seems to grow from the rocks from
which the water runs over. Everywhere else there is no algae in the pond.
Thanks

There are lots of different kinds of algae.
The ones pond keepers deal with a

suspended algae - tiny cells that float in the water and make the water pea
soup green.
string algae - fibrous strings of algae that looks like long, green hair
substrate algae - looks like a fuzzy green sweater and grows on surfaces

Algae in waterfalls or water returns tends to be string algae or substrate
algae.
String algae - just remove.
Substrate algae - leave alone or scrub off if it really offends your eye.

All algae grows because it has the nutrients it needs. Sun, fish waste, rotting
plants, blown in dust and dirt, fertilized run off, fresh water.

Everywhere else there is no algae in the pond.

Oh, there's algae in there. You can't have water outside and not have algae.
There is algae in the waters of the artic! This is tough stuff. It is just not
in concentrations that you can see it. For now... One thing about ponding,
never rest on your laurels.

I have shallow water floating algae...which is caused by less than 1
foot shallow areas in the pond. The water heats up faster in those areas
so algae grows before your eyes....no kidding!

In the afternoon you can see oxygen bubbles all along the shallows pond
bottom...and also see algae strings break off little by little. It gives
off tons of oxygen!
good for fish!

Solution...is to make the shallows deeper or...SHADE.....or put a
waterfall in that area to cool the hot spots.

For me in the summer I just shade it.

String Algae is filtering out nutrients as they enter the pond to stay
alive. Moving water brings nutrients to the algae, so water that is low
in nutrients will bring the nutrients to the algae where there is flow.
Apparently it is doing a good enough job to make the rest of the pond
not receptive to more string algae growth. Also, there is no flow in
the rest of the pond so that string algae doesn't grow.
