I think even 10 turbos are too many.
Personally, I think those reeflceaner packs are way, way over stocked. A lot of the animals will die off from starvation. I'd rather spend the money on improved filtration. 2 serpent stars, 10 nass snails for the sand, 10 ceriths, 10 small hermits, and a few turbos would be all I would do. (and probably more). A good urchin can replace a lot of snails - they're cooler looking, faster, and hardier, IMO. Also a shrimp will do the work of several hermits as well, as far as eating leftover food and dead stuff.
As far as algae control, again, I'd rather focus on reducing phosphate and NO before getting more CuC - they just are treating the symptoms.
