Orange stuff growing on rock -

[jh2pizza]

I have recently lost zoo colonies I have had for years. My blue mushrooms are starting to die off and it seems everywhere there is a problem, this Orange stuff is growing on my rock work.

What are you water parameters? What type of water do you use, tap or RO/DI? What type of suppliments? Have you serviced all of your pumps and other equipment? Could there be antyhing leaking into the tank or corroded metal near the tanks... etc etc.

You need to provide as much detail as possible.

Have gone through all the pumps. I use Ro water and do frequent changes. I do not dose anything. I use a Kalk reactor and dose Randy's Two-part recipe.

The photos is too fuzzy to tell what it is. I have both sponges and coraline algae of that color in my tank.

it also looks like it could possibly be fire coral. Can you see any tiny hair-like structures coming from the surface? What happens if you touch the orange area, if you ever have? FIre coral will cause a minor irritation of the contact area.
