I don't think that much calcium will hurt anything, and with 2 large clams it will be down soon.

It's more about the alkalinity/calcium ratio IMO. No, calcium that high shouldn't hurt anything and you are obviously dosing to get it that high. Just trim back on your doser and let it come down gradually on its own. Depending on where you like to keep your Alk should tell you where your calcium should be. If you keep your alk at 9 dKh, then the ideal Ca is 425 ppm. If you keep your alk at 10, your Ca should be 432 ppm. Its best to strive for that ratio. Your clams can't utilize the extra calcium without the extra alkalinity. It is costumed in a ratio to build their shells. To have the proper ratio with Ca at 487, your alk would need to be 17. Obviously too high.
