Also, I have a large ramshorn snail I'd like to keep and
hundreds of MTS that I would really like to keep (I think the population is
healthy enough that It would be hard to get rid of them, though.)

Not a Columbian ramshorn, is it? The ones that get to be 1" or bigger? They
are terrible plant-eaters.

1) Lots of ghost shrimp. Will these eat snail eggs?

They will eat snails. But not enough to control the population. They can also
be quite predatory with small fish.

2) Some kind of small loach. I'm having a hard time finding specific
references to non-clown loaches abilities to do this. How are kuhlie
loaches?

Kuhli loaches will eat snails. Loaches in general do a great job on snails.
Unfortuantely, they won't just eat the pond snails. They can even kill snails
much larger than themselves.

4) Any other ideas? I'm open to anything.

You could try trapping them. Bait them with a slice of zucchini or lettuce
leaf in a jar.

Or you could just live with the pond snails. If you don't mind ramshorms and
MTS, why not pond snails, too? IME, they don't do any harm, and are terrific
algae eaters.
