Frag disc on mariculture acro reef safe?

[Bacon505]

Anyone know if the material used for frag disc on those indo ariculture safe for our reef? They look like some kind of ceramic. Reason im asking is i ran out of frag disc and i have a few of those from the mariculture pieces that’s sitting in the backyard for several weeks soak in the sun.

I think that if coral can grow on it then it should be safe in the tank.

I always reuse them. Doubt you will have an issue.

Its all dried out so im sure all the hitch hikers are dead(i hope) just arent sure about the material.

I have cut through one or two of these wierd odd bases that have some black nasty stuff in the middle that gets everywhere on the bandsaw but still put them back into the tank after a rinse.

That's likely from anaerobic or anoxic conditions within the base. Most of these discs are calcium carbonate based cement and are safe
