Dynos or cyano?

[cillam]

I have this red stringy stuff growing on my sand is this dinos or cyano.

could be either. dino's do come in red, i believe. but my vote goes to cyano.

just as i asked in the https://www.reef2reef.com/threads/help-is-this-dino’s.1048354/ thread: what are your water parameters? what is your filtration?

Checked everything 2 days ago. Measurements are.

Salinity 1.025
Ammonia 0
Nitrite 0
Nitrate 15
Phosphate 0.14 was .03 2 weeks ago.
Calcium 440
Alkalinity 9.0
Magnesium 1250
Ph 8.15

As far as filtration goes the water from the DT goes to a filter sock in sump, then protein skimmer, refugium with bio blocks and cheato, through a bag of activated carbon and back to the return pump to the DT.

Just got the cheato 1 week ago dosed some cheato grow. Think this could be fueling it?

the chaeto definitely is contributing to your nutrients bottoming out, too. remove skimmer cup and let water run into your sump so it doesn't lower your nutrients but adds oxygen back into tank.

also, https://www.reef2reef.com/threads/help-is-this-dino’s.1048354/post-12420366 and follow my suggestions there. should help with either it being dino's or cyano.

last pic looks more dino-ish than cyano.
(but, it can always be both!)

A little update on this. vacuumed the sand bed and through a filter to capture all of the red stuff, then started dosing 1 ml of Peroxide per 10 gallons of water twice a day. I scaled back how long my lights are on. After dosing peroxide for 4 days i then dosed with Chemiclean and left it in for 3 days then performed a 25% water change. I no longer see any of this stuff on the sand or rocks but its only been 3 days.

Looks to me more like dino. Can't go by red colors to conclude cyano. Dino often starts when they consume po4 and no3 and cause biological deficiencies often assumed to be the cause.
No light is first key followed by the addition of bacteria to overcome the bad bacteria allowing them to thrive
Prepare by starting by blowing this stuff loose with a turkey baster and siphon up loose particles. Turn lights off (at least white and run blue at 10% IF you have light dependant corals such as SPS) for 5 days and at night dose 1ml of 3% hydrogen peroxide per 10 gallons for all 5 nights which works as an oxidizer. 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 AMINO OR ADD NOPOX which is food for dinos, however you can feed coral, food which will help no3 and po4 to increase. If increasing nutrients, try to keep no3 to about 5 until you are done battling these cells.
Doing a daily siphoning will help greatly But . . . . . Siphoning will reduce nutrients , so siphon the water into/through a filter sock and save the water and return it back to tank. Obviously clean the filter sock each time.
You can feed fish as normal and if doing blackout, ambient light in room will work for them
