Cyano or Dino

[cklop09]

Cyano or Dino? That is the question.
Pictures taken shortly after killing the lights.
I've noticed this getting worse in the sand as I've been restocking my tank. Post brook/fallow period.
It definitely dies back at night with the lights off but not completely. And takes about 2-3 hrs to resurface the next day.
Tank is 90 gallon w/eshopps sump
Bubble magus curve 5 skimmer
2 jebao slw-30 running 75% on random mode
Nitrate: 3
Phos: 0.125
Calcium: 430
ALK: 10.5
Mag: 1350

Ive been doing about 5-10 gallon water changes every 3-4 days and vacuuming the sand bed during those changes. Following up with MB7.

My nitrate was down to 0.5 a few weeks ago and I've gotten it up with NEO NITRO

I think it's cyano, but dont take my guess for granted, wait for more answers.

Can you get a microscope? I think it like cyano as well... but you will want to know for sure.

 

[Santervas]

if it is only in the substrate and you have high silicates, I think it is diatomena

 

[Santervas]

diatom

The disappearing reappearing can point to dinos. Any bubbles on it?

 

[Velcro]

Borderline impossible to tell diatoms apart from amphidinium Dino’s without a microscope.

 

[thedon986]

Cyano does not disappear at night like dinos or diatoms would.

Haven't noticed any bubbles in it. It's starting to creep onto the lower parts of the rocks

I have phosguard I could run through a reactor and see if that knocks it out

I dont have a microscope, I could ask around for someone nearby who does

 

[thedon986]

In my experience, diatoms do not form mats and will break up like dust when disturbed and definitely won't creep up rocks. If you disturb it and stays somewhat clumped up but also disappears at night nearly or completely you are probably dealing with dinos resulting from bottoming out nitrate. I had a coolia bloom when nitrate was too low and amphidinium bloom when phosphate was too low.

I was worried about the bottoming out nitrate a few weeks back =/

Has the red of cyano but when I had low nitrates and coolia bloomed it was very red too. I would get a $30 microscope, something that does something near 1000x and you can identify exactly what it is. It's a good investment that will let you identify this and all pests of the future.

If it is coolia, how did you beat it?

 

[thedon986]

I don't see any of that anymore but I still have amphidinium, coolia responded better to silica dosing which you can read about in the amphidinium dino thread. along with raising nutrients, add bottled bacteria of different types, you can also look at the Dr Tims Dino method and/or Elegant Corals dino method.

I've been adding MB7
I have some bio-Spira I could try too
I've been working with neo nitro, trying to get between 5-10ppm
Ill Def check the others out too, ty

So today I noticed a good film on the glass and it had these little bubbles on it, very small in size. Starting to think it is dinos after all =(

Get a microscope to make sure. Some cyano can present that way on the glass, too.
