nitrate sponge stones

[lilrobb]

Does anyone know if (and if so, how) those zeolithic nitrate sponge stones can be recharged?
I have a ton of these and could really use them right now.

Don't know if this is the stuff your talking about but here's a link to Purolite:

Is that the same stuff as Zeolite?

It's not zeolite.

It's porous substrate that makes a good habitat for denitrifying bacteria.

Should not need "recharging" but can be re-used. If they've been allowed to dry out, rinse them well to get off any detritus etc., but they should be fine to re-use.
