Toadstool with white spots

[w_1qaz]

I have a fairly large toadstool that has started showing white spots on it.
Any suggestions on treatments would be greatly appreciated.

Thanks

You have pictures? Maybe flatworms?

It could be just about anything. If on the top of the toadstool I'd say it was detritus settling and you need a bit more water flow.

What's your water parameters at? Nitrate etc...

I had the same thing on a finger leather. I moved to to a lower flow area of the tank and it went away.

nitrates are near zero. it gets some flow from a HOB just above it and a powerhead every 3 hours that is about 24in away.
my other smaller toads are just fine and are blasted with way more flow than the larger one.
would a CoralRX dip help?

Thanks​

@w_1qaz what's the status on this now?

Sometimes white spots form, and they become a hole in the top of the coral, which slowly works it's way outward, to drop a piece (sometimes a large piece) off, to form new corals.
Mine is currently in the process of doing so
