I don't run the waterfall very often and wonder if it might be better to
have a separate pump for the biofilter or if it is better to have one pump
but with an outlet for each. I suppose alternatively I could try to locate
the biofilter at the top of the waterfall which would deal with both jobs.
I was also thinking of getting a biofilter with a UV lamp to deal with the
algae.
======================
I'll skip giving advice on pumps and filters as I'm not qualified to do so.
As for the goldfish population - if you keep no more than 4 or 5 real nice
ones per 100g the water quality would be better and there would be less
algae. Goldfish breed like crazy and do get large. They eat a lot and pass
a lot of feces to feed the algae.

The UV lights do work! But then my ponds and grow-out tanks are not too
crowded and do contain plants. Plants compete with the algae for nutrients
and are attractive additions to any pond.
