Green rock

[lamjiasheng]

My tank is only 4 months old.
Is this sign of tank maturing or sign of green hair algae coming.
How long will it take to get rid of this ?

I don’t see any pictures to evaluate your situation but at 4 months the greening of the surfaces in a marine environment is not unexpected. It could be coralline algae or green slime or hair algae’s starting to develop and a year from now the tank will still be doing its thing unless you tear it down because you don’t want green stuff in your reef?

Add pods and snails for increased diversity if you haven’t already?

Hth!

EDIT: now I see what you mean. How long do you have your lights on each day? Something is starting to grow where the light is brightest and it looks like a good start, probably green hair. Perfectly normal for a new tank to get started with some life on the bare substrates.

How long? Eventually the rock will be covered with coral or coralline algae but the time it takes to get there is unknown to me.

Lights on around 10 hours a day.
Was 8 previously but the red candy zoa doesn't open fully compare to other zoa I have, so I'm experimenting to find out the cause of it.
Red people eater and gobstopper zoa fully open at its best appearance but the red candy just won't open somehow
