Does anyone know wh my Kenya tree coral is turning brown and pale? My levels haven't changed.

I got a Watchman Goby and a Pistal shrimp today. They seem to be very happy.

Hello all, I am brand new to the hobby. This is my very first reef tank. It is a TMC First wave 48L (UK measurement) in the past, I had cold water and tropical fish.

I started this tank on Jully 11th 2026. I'm thinking of getting some black pvc sheeting for the back of the tank, which I will put on the outside.
