Jesus Murphy, How did it get so high!

API calcium test kit known to be inaccurate, usually reads high. I will suggestion you testing it with a different test kit (elos, hanna, or salifert), or bring your water to your LFS and ask them to test it for you, using one of higher quality test kits.

if your dosing calcium im assumiong you have alot of high demanding corals or at least a full tank?? its def not a good idea to dose anything without testing for it reguarily

I would say you have a false reading. You would think that if it was that high you would have calcium precipitation. this is just my thoughts about it! You could also take a water sample to your local fish store and ask them to test it for you or ask a friend to come over with there kit and retest it!

A single clam isn't going to move the Ca level at all. And if it's that high for real, the chemistry might be so messed up that nothing can use it anyway. But I'm pretty certain it's not really that high.
