I'd start with 1 or 2 balls, they need room to roll around to keep round and healthy, see if your turtle attacks them or not. If not they are cheaper to order bulk on line.
I think their ability to keep algae at bay is overstated. They are such a slow growing plant I don't think they use up as much nutrients as people say. So if your looking at these as a source of algae control this may not be a solution. You maybe better off with fast growing stem plants like anacharis, Ludwigia, Cabomba, water lettuce, etc.

Also if I get the moss balls, will there be enough algae to sustain a pleco? If the moss balls can keep all the algae at bay and Angelina doesn't eat them/tear them up, I'd rather go that route simply because the pleco will just create more poo.
I'm also wondering if I should invest in another filter. I have an FX5, but I'm wondering if having a smaller filter with the intake on the opposite end of the FX5 intake would help anything. I'm not sure it would since my water is in good shape. Thoughts?
