Recently purchased this Leather toadstool been in absolutely great health however last few days it seems to have a pale yellow appearance to the stalk and seem outer layer to be peeling away.
I've had marine aquarium for 9 years since year 3 now upper sixth form but only recently purchased this leather however had green stripped mushrooms in the aquarium without any problems.
All the water quality seems spot on with no issues but KH
value in dKH
Could someone give me any advice as don't want lose the coral.
Many thanks Matt
