Well lets see.... This is going to be long....I have pond plants, but
not nearly enough no doubt. I have water hyacinth, I purchased 20
"baby" plants and then bought 3 large plants each with two medium sized
plants growing off of them for a total of nine plants. So, 29 Hyacinth
which really areant multiplying very much-or at all.(Did get my first
bloom today though!) I also have a few water lettuce floating around. A
couple of bunches of anacharis and something else I cannot remember
the name of. One potted water iris and two water cannas. I had several
water lillies but they got snipped off by a snapping turtle that moved
in, since been evicted by me! I rarely feed the fish at all, maybe once
a week if that much. I only have 8 3-4" long goldfish in the pond. No
tadpoles. (Although, on a side note, my front pond had a crazy amount
of tadpoles, not so much anymore,ahem.. The front pond gets a little
less sun everyday. It was pretty clear for the longest time after the
back pond greened up. Just recently, we had a week where it rained
amlost 7 days in a row, now the front pond is greening/clouding up.
Figures since I just put a small koi and a sarassus in it. Cant see
them. Got a UV coming for that one too.) No fertilizer run-off, I did
place a some mall chunks of fertilizer in my lilly pots right before
the turtle decided they needed to go. Also, I really do not have any
circulation other than whats going through the UV Which is still about
1/2 the pond volume an hour. I lose an insane amount of water with the
falls on so until I can get it lined it stays off. No biofilter to
speak of. Im working on one now, its supposed to go at the top of the
falls though-so oh well. I know that definately isnt helping matters,
but, I only have 8 fish in a 1750 gallon pond.
=======================================
I would say at this point to just have patience and see what happens. You
have adequate plants for the number of fish involved. Keep checking for
turtles as they pass large amounts of feces every day. Bird dropping are
very rich in nitrates. You may try covering 2/3s of the pond with something
that stops light until the UVs catch up. You may also try one of the
colored water shaders that supposedly starves algae for light. Something is
feeding your algae, that's for sure....

I read that a lack of "iron" can also cause pond plants to fail amid plenty
of N-P-K in ponds. If they're not thriving they're not using up the N-P,
and so the algae are utilizing it.
