Hello, can anyone help with information on what this Algae or mushroom stones are?

Brown is slightly transparent and slimy is easily removed.

The water parameters are within normal limits after ICP analysis.

Thanks !

How long has the tank been running?

How long has the tank been running?

About 8 months with lighting 4 pcs. Radion G6 blue.
I doubt that I brought any corals, even though I dipped them.
Also, my nitrate and phosphate levels are low and I notice that it is getting a lot more magnesium.

I still have a few corals for an 800 liter display volume, but they feel good brightly colored and open.

Looks like chrysophytes (golden algae). It's generally not harmful, just ugly. They do well in low nutrients. Cerith snails and amphipods eat it. Raise nutrients, manual removal, add some competitors.
