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?

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!

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!

Change nothing. Do nothing. It's normal.
