I hooked up a 300 gallon rubbermaid stock tank to my 1300 gallon pond. I put 3 water lily in it with daphnia in my 300gal. tank (tub) with slow running water from one of my filter outlet. The daphnia multiply and ate all the algae. This will also make a good ecosystem. My daphnias are use to feed my fancy guppies frys, african cichlids frys and koi frys. The uv sterilizers will do the same thing as daphnias but waste electricity bill and sometime are made for certain size pond only. Chemical works but aglae will grow again
good way to get rid of pond aglae without using a uv sterilizers or chemical

I would say invest in a UV sterilizer. Or get a UV sterilizer built into a pond filter. Less on the electricity bill. 
Do you know how much uv sterilizer cost for pond? Well it a lot. Plus that thing just hook up to your pump system and you don't even know if it working or running. The natural way is daphnia. Can you imagine that you have a giant pond. Stock it with daphnia first and than your fish. A uv sterilizer is not good enough to run a giant pond. I am just trying to make use of daphnia with the life cycle of fish or pond. To feed fish and clean pond.
You are correct about the cost of UV sterilizers. Plants will work for a lightly stocked pond but most people keep more than a few oversized fish. Plants actually clog filtration and too much plants can actually deplete the water of oxygen. Great tip on the balance of the ecosystem.
They do make UV for lakes.

You can tell if the UV light is working or not. My UV sterilizer on my filter has a small hole where you can see the UV light. I know its expensive but its worth it. Are you running any UV sterilizer on your 1300? You can also go with plants like kendragon stated.
just use bullfrog tadpoles. im not 100% sure its gonna work. but I only heard they eat algae. just feed them ground up flakes and sadly they will grow to frogs. ur koi will eat the eggs to controll their population.
The white famale koi was red llke the rest. It got sick and loss all it's color. Got these koi for $100 each at about 9 inches long two years ago. I try to get more but the koi show sellers would not sell any for $100-150. They asking too much. So I did not buy any last year. I don't want to over stock my koi because koi fish need's special koi food. Not the cheap one. That how it gets it color. If you feed them cheap fish food. The color will disappear and not be so rich red. I just need to 4 more koi fish to my collection.
Bullfrog tadpoles is a bad idea. You don't want to hear noisy bullfrog sound coming from your pond and I don't know what bullfrog eat too. Maybe small fishes and bugs. Pond snail are better than bullfrog tadpole. Pond snail has a soft shell that koi fish can eat. Koi fish can eat snail eggs too. I just don't like pond snail because they mutiple to fast. I do have pond snail and ram snail in my ponds.
