Skeletons & Reactors

[The Floodinator]

I have some skeletons from corals I've lost and I'm wondering if they would be good to use in a calcium reactor?
They sholud have the proper chemical make up, right?
Anybody do this?

[bertoni]

The skeletons are largely okay, but they might have picked up more phosphate or trace elements, as compared to a regular reactor media, so I'm not sure that I'd use them.

[The Floodinator]

They are still in the tank, could they pick up the phos. etc. from the tank water?

[bertoni]

Yes, that's the issue. Phosphate can adsorb onto calcium carbonate.

I did not know that.
As always, thank you for being wiser than me!
