What type of algae am i fighting?

[mistahken]

Tank has been up and running for about 6 months now, i understand diatoms takes over at a certain point but this stuff ive never seen before and it will not go away.
My parameters are the following
PH-8.2
Salinity- 1.025
MG-1450
CA-445
DKH- 9.0
Temp-79
im waiting on the phosphate testing kit to come in the mail.

I've cut back on the whites, cut back the entire lighting cycle and not much has changed, I have tried phosgaurd and it does help within the first couple days but then this stuff just takes over again.

Pretty sure its ticking off my hammer coral because its not coming out as much anymore

There is plenty of flow in the tank as ive tried moving the power head around to see if it was a flow issue

Looks like the start of a cyano outbreak to me. If you pull it out of the tank, does it have a really strong odor? Is it slimy?

When you say you have plenty of flow in the tank, how did you determine that?

It is slimy but the odor im not sure about i just picked some out and its very slimy.

How i determined i had enough flow is i based it off the corals reactions, i have 1 single powerhead of 480 gph in a 26 gallon, i have a matching one but both of them makes it a whirlpool lol

Slimy makes it sound like dinos, particularly amphidinium since they're on the sand bed.

Check the stickied dino thread and do the cyano/dino test to see which it is. If you have a microscope, that can also help you tell.

Looks like Dino’s or crysophytes which if it is, phosguard would cause way more issues , they thrive in low nutrient / 0 phosphate 0 nitrate and Dino’s are toxic

so not to sound ignorant, but what's the solution? i use to keep reefs but it's been a LONG time and im trying to refresh as i go.

I had to fight Dino’s to lol ,It depends on the exact algae , need a microscope to ID for next steps in nuisance algae forum there’s a sticky for fighting Dino’s over 600 pages @taricha is the OG
For me it was osteoporosis which is the most toxic but easy to get rid of , I had to dose nitrate and over feed like crazy and install a UV into the DT followed by no lights for 3 days to allow other micro organisms/algae to outcompete the Dino’s, they still exist waiting for my nutrients to drop to 0 to come back but not on my watch haha
