Diatoms vs sand dwelling corals

[BryanB]

How do diatoms on sand effect sand dwelling corals? For example plate coral, chalice, and open brain types

 

[Reefing Madness]

They won't reside on the corals. Only there to eat out the silicates in the water, they generally don't happen onto the corals, that I've seen.

Ok this was more of a curiosity than anything
