Cyano? Dinos?

[Salty Hippo]

First post, need help.... Can anyone tell me what this is and how to get rid of it. My Phosphates .04 and Nitrates 5. Been doing 25% water changes weekly using RO/DI water 0 tds.

Definitely not cyano (at least on the sand). How old is the tank? It could just be regular diatoms and algae that every newer tank gets. But I'm guessing it has been up for a while?

It’s been set up for around 14 months.

How long has the tank been up? I've had green cyano that looked like that before. Does it blow off easy with a baster?

Yes it blows off easy and comes back within days of vacuuming it from the sand.

the reason am asking was this: handy to keep in the back pocket. of course all practical means first, but what tank surgery can do is slick neat hard work. strong potential backup for when things get worse, the #1 thing we thought could not be safely done has now been done 200 times here's one matching your reefs size.

zapping them clean by work is also an option
