Hello everyone, recently I started to see hair-like film algae appear on my rocks, at first I thought it was diatoms because of the hairiness, I thought that dinos were more snot-like. I went to my LFS and picked up 5 Astrea snails to eat the supposed diatoms (Pic of the film):

I don't know if these are dinos or not, but here is the why it is or isn't:
Why it isn't dinos:
⦁ It is a brown hairy substance, not a snotty bubbly slime like I would see in other images.
⦁ When I put the Astrea snails in, they would make a trail of clean rock.
⦁ It does not go away at night
⦁ I think it is a diatom outbreak because recently I put new refugium sand (not mud) in my fuge, and it may have produced some silicates that fueled a diatom outbreak
Why it is dinos:
⦁ The Astrea snails did not do a lot until a few days ago
⦁ There are a few bubbles on the rock
⦁ My nitrates bottomed out (0-1 ppm)
⦁ When I looked under a microscope I saw this:

This picture was taken at 100x zoom
If anyone could have any input on what is going on then please comment.
Some tank info:
My 75-gallon tank has been up for a little over a year now. I started with dry rock (uncured) and went through the normal ugly stage (first diatoms then GHA) but It all cleared up eventually.
My livestock (in order of purchase first to last):
-2x Ocelaris clownfish
-2x Red firefish
-1x Cherub Angelfish
-1x 6-line wrasse
-1x Banggai cardinalfish (I will get another one)
My nutrients have been pretty low (nitrates 0-1 and phosphates are undetectable because of my stupid test kit)
If anyone could ID the dinos/have opinions on this please reply,

Thanks so much.

Possibly Chrysophytes....the look like tiny, golden, non-moving circles under lower magnification.

As it appears to be chrysophytes, i recommend going after nutrients (nitrate and phosphate) and manual removal. Have you measured nutrients (phos and nitrate) ? You might also check soluble silicate. Some Chrysophytes use silica to form structures, but I do not know if the type you may have do (or actually, if it is even a Chrysophyte).
Bumping up skimmer and even adding a pouch of chemipure elite will help. Also what will help is:
- Made it a point to change my filter socks more regularly, at least 3 times a week.
- Limit use of flake food, and try to focus on frozen.
- Reduced lighting time

Thanks, my nitrates right now hover around 0-1, and my phosphates are pretty mutch undetectable because of my test kit. I am thinking of ordering a Hanna ULR phosphate checker, also when you say "go after nutrients" do you mean to raise or lower them? I am running carbon and my LFS also recommended Chemi-pure. Sorry, one more question, when people say "skim less" or "skim heavily" what do they mean? Do they mean making the skimmate a denser, browner color? Thanks for the help.

use of the skimmer. . . which can remove nutrients. I did not stop my unit during treatment but you can if they are low.
Going after nutrients = assure they are not elevated and adjust accordingly

How's the battle going? I have just now finally got a microscope to properly ID my dino's and am beginning my removal battle. I went from high nutrients to bottomed out so now I'm sturggling to get nitrates up. I bought bottled bacteria today to try to help out until my BRS shipment comes this week. I also ordered more tisbe pods as they are known to eat dinos. Good luck and keep us posted please.

Hello, thanks for your interest, from what I have gathered, Chrysophytes are a type of diatom, so there is probably an excessive amount of silicates in my water, that came from my new refugium sand that I put in a few months ago. I am trying to elevate my nutrients to not have a dino outbreak in the future. I am dosing ChaetoGro for my refugium and already my chaeto is looking better. I am taking more of a "passive" approach to beating this, I think I will let it take its course, but if it's still here after a few months I think I will take more of an aggressive approach like heavily skimming and Mabey adding chemi pure. Good luck!
