Yellow color algae?

[JayChen]

I wonder what kind of algea is this
Ammonia 0
Nitrite 0
Nitrate 5
pH 8.2
Phosphate 0.25
Should I dose chemiclean? I heard that thing kills corals. I have filter floss, chemipure elite, and purigen for my media rack. What should I do to get rid of it?

Looks like either diatoms or dinoflagellets. Leaning towards diatoms. How old is the tank?

Less than 2 weeks

Probably diatoms then. They are harmless. They disappear on their own once silicate is eaten. Give it a few weeks.

So should I decrease the time for lighting and reduce feeding? Thanks a lot!

Not necessary but wont hurt. Silicates come from tap water mostly.

If your tank is cycling. You dont even need light at all.

Sorry looking at the pic, you already have fish and corals in there, I assume you have used a bottle of bacteria to start your tank. If so then leave it as is and as said above, the diatoms will die off.

Yes I used a bottle of BIO spira and it worked like a charm!

I myself have always done the long cycle, so I cant comment on the bacteria in a bottle. But cyano comes in all ways of starting a tank and will go sp don't worry.

Change nothing. Do nothing. It's normal.
