Does anything eat Diatoms efficiently?

[Fisherman Joe]

I have a reef tank with lots of wrasse, again all reef safe.

Is there anything that eats lots of Diatoms?

I have found cerith snails and conch do a pretty good job.
Are you sure its diatoms? is it a newer tank?

Pods eats diatoms. Wrasses eat pods.
