Please help. What can this be? Here are the pictures.
At first thought maybe Bubble Algae, but then there are bubbles to thin and microbubbles. Then i thought maybe cyano or dino or diatoms...Now someone told me maybe the skimmer. Just confused....anyone with more experience any comments?

My tank is 3 months old.

It looks like its from the algae, but you could test it by shutting the skimmer down.

So you say to turn off skimmer and see if that eliminates the bubles on the rock? For how much time should i test it? Thanks

Blast the bubbles off the rock with something like a turkey baster. Turn the skimmer off for a day and if the bubbles are back...its probably not the skimmer. You should be able to see microbubbles in your water column if its the skimmer.

looks to me like you have a little cycle going on, they may be nitrogen bubbles from the bateria in the rock.

Bubbles from the rock would float to the top of the aquarium. That looks like dinoflagellates.

gonna have to google "dinoflagellates". Last time i seen bubbles like these is when i changed my office tank from a 15 to a 20 long and added 8 more pounds of cured live rock, only the new live rock had these bubbles. I also got a diatom spike when i switched tanks, it all went away after a week or two.

Tthanks for all the responses.
As you see i did make my research and could not find one that i can really say ITS THIS TYPE OF ALGAE. seems like a mix of GHA, bubble algae, cyano, dinos.

See it is hard to tell. everyone sees something different. So i still dont know how to battle it. Any ideas?

Lots of GFO in a reactor, elevated PH, and possibly Chemiclean. I can eliminate one of those algaes for certain; its definitely not bubble algae.

This is bubble algae:

What are your phosphate and nitrate levels?
