i have this on my rock and it was irritating some corals. ( it look like a brown slime like spider web) Can you help how to get rid of this on the tank without throwing to rock. Thank you in advamce
You can siphon it out or use a power head to blow it off rock. Then use a net or siphon it out of tank. Red slime or cyano. How long the tank be running? Young mature tank or nutrient are high.
Based on description of irritating corals and what I can see from the picture I would guess Dino’s. Lower your nutrients and increase your flow. Check online for other ways to get rid of it. Not easy.
