Does any one has ever seen this in the refugium? Is it good or bad?

This is my refugium. Displays seems ok so far... should I be worried?

Well I wouldnt worry , but you dont want it to take over. How much lighting vs flow you got going on in that fuge ?

Light is on at all time - 24h/7days!
Very low flow

So that is most likey the cause , light should be on opposite of DT ,and you need flow , my fuge has over 1000gph going through it. Your creating a stagnant cesspool in your system .

Run the light same amount of time you would for display. Having reverse cycle won't do much if it's small.

Flow is up to you
