So i suspect I have dinos.

90gal, running 3 months
Stocked from a near 2yr 30gal, most rock used, some dry rock.

Tank was filled with all new live sand.

Parameters.
Nitrates 5ish
Po4 .25
Salinity 1.027
Alk 9.5
Calc 460
Mag 1350

Lighting is dual 250w 14k halides running 6hr a day
4 48inch vho, 2 blue 2 actinic 10hr a day

Just added carbon today.

Been dosing peroxcide at 1ml per 10gal for 4 days twice a day.

No corals seem bothered, ive scrubbed massive amounts of bubbles of back glass. Nothing seems posioned.

Pics.

@twilliard and anyone else who cares to chime in?

Looks like bubble algae and cyano to me

Might be spirulina, being no reaction thus far to peroxide.

The reason i thought dino, and its hard to see. But the second pic theirs these brow stringy things coming from the algae. Theres so many variatuons its hard to guess

Yes indeed this is hard to tell.
Are you able to siphon any into a bucket and do my bucket test?
At first thought I thought no to dinoflagellates
But highly possible it's a bacteria (from the notice of o2 bubbles)

Iwill search for the bucket test and try it.

Siphon some up in a bucket and give it a good swirl
If they hold together as the water settles then it is dinoflagellates
If it makes a mess on the bottom then it will be a bacteria
