On the algae, there's something called a UV sterilizer that's supposed to take care of algae. They are sold at water garden equipment places. I don't know how safe they are for turtles. Here's an ad:
Aqua Ultraviolet ( UV ) Sterilizers for Ponds
Turn Your Pond From 'GREEN' to 'CLEAN'
Ultraviolet ( UV ) sterilizers are a very effective way to control green water algae in ponds, as well control other unwanted elements.

UV Sterilizers can also be used to control the amount of harmful bacteria and parasites in your pond, while creating a healthier environment for you pond ecosystem. When using UV Sterilizers as a water clarifier, it will clear your pond of green water algae quickly and effectively, without the use of algaecides.
