chrytophytes?

[David_CO]

In the last week this stuff has started to pop up and spread through my tank. At first I thought it was Dinos, but under the microscope it doesnt move at all. After further research I think its more likely to be chrytophytes, which unfortunately doesnt seem to have a consistent treatment option. Based on what i've read I think im going to bump my nutrients a bit and see how it responds unless im given other guidance.

Tank Parameters:
SG: 1.026
Calcium:415
Alk: 7.9
MG:1350
Nitrate: 1.9
Phos:0.02

Below I posted a pic of what it looks like in the tank, microscope pics and a video.

This looks like dinoflagellates
Prepare by starting with a water change and blow this stuff loose with a turkey baster and siphon up loose particles. Turn lights off (at least white and run blue at 10-15% IF you have light dependant corals) for 5 days and at night dose 1ml of 3% hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off. During the day dose 1ml of liquid bacteria (such as micro bacter 7 or XLM) per 10 gallons. Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX

Dinos that don’t move at all under the microscope?

other thing to note my turbo snails, Trocus snails and urchin eat it

agree on chrysophytes.
look very much like dinos, except under the microscope. Not susceptible to UV.
Treatments are not well established.

ty Taricha. can confirm my oversized UV is doing nothing.

+1 on Cryso / golden algae

Silica deprivation could help…

I have a dual stage DI RODI unit and the beads look good with not alot of gallons through but probably worth looking at. I did have a diatom bloom 2 months ago but at the time I attributed that to a new tank with some inherent silicates in the sand.

I’ve got these and best removal so far I have found is manual toothbrush scrubbing. Just work in sections let it go down the overflow to pick up in filter bag or floss. Persistent cleaning is key! My rocks are mature so they aren’t growing back in areas I’ve scrubbed.
good luck dude if you find anything else out lemme know!

Have you tried dosing dinox yet?

In my opinion, the organism we're discussing isn't a silica containing one.

It gets confusing because "chrysophyte" was once a general term for many forms of golden brown algae including diatoms. So older sources may talk about "chrysophytes" including silica using organisms.

So I'm saying chrysophyte in the sense of a member of the order chrysophyceae.

I just dose dinox a few rounds for the past week. Chrysophyte hasn’t budged! If you find something please let me know. They actually got worse since dinox treatment.

How did this turn out?
