Below are some tips by a fellow ponder of mine. I'd like to know what your
water parameters are currently: Ammonia, Nitrite, pH, KH, NitrAte, if you
can test for those? How big is the pond and how many fish? Type & sizes?

Algae fighting tips

~ New ponds and spring ponds need time for plants to get established, algae
is quicker at getting going!
~ add LOTS of plants, of any kind, in the pond. Especially underwater
plants.
~ Shade is good - provided by lily pads, floating plants or artificial
shade for part of the day.
~ LOW fish stocking (20 gallons per goldfish, 100 per koi) and not
overfeeding the fish.
~ building a mechanical filter to screen gunk.
~ build a veggie filter, run water through plants, as easy as floating
water hyacinth in your filter.
~ clean up dead plant matter and screen for falling leaves
in the fall.
~ water movement, water changes of 10%/week
~ add a sludge consumer, concentrated bacteria.

~ building ponds with bottom drains and skimmers.
~ do not use algaecides, they only make lots of suddenly dead algae
and that will feed the next algae bloom.
~ gently remove string algae
~ patience ;-)
