Hi Kerplunk,

All algae thrives on sun, fresh water, fish waste, fertilized run off,
rotting plants and blown in dirt. In new ponds and spring ponds algae
is always the first thing to start growing.

The best defense against algae is to have lots of plants, plants and
more plants to compete for the nutrients, few fish, not overfeeding
those fish, some shade and cleaning up debris. And since you have
turtles they also add to the bioload. Can you reduce
your goldfish population?
I have four turtles in 3,000 US gallons and that will be my next
step, cut down on the rampagingly reproducing goldfish!
