Hi Reefmania, I'll have Alexander give his opinion, as it's appears to me to be dinoflagelletes, which Alexander has previously won this battle...no easy task though. Bob

Its really not easy to indicate them by a picture even if it is a good one. Dinoflagellate and Diatoms does look very similar. You can easy find this out by placing them under a microscope. If they move, you can be sure those are Dinoflagellate. I have posted a small video showing them in action:

Do you have this stuff in the whole tank, have you massive dosed Zeobac or any other carbon source beside ZeoStart / Food.

So you have seen them under the microscope moving ?

I have done a lot of experiments but where not able to get rid of them. This stuff was just unimpressed whatever I have done. I had some kind of hose in my system which leached toxins and I think this was the reason for the outbreak. After removing the hose they went away within a couple of days.

I've only a microscope for children...and i've had the impression they move.
I have hoses used for food...have you a photo of the hoses? are they for food use?
I'll try to see them with a professional microscope.

In your opinion is it possible the reason is the low interchange tank-sump?
The tank is about 550 lt and the interchange is about 1000 lt

I would not expect the relative low water exchange between the sump and the tank has anything to do with this stuff. Because of hoses I personally prefer just to use real silicone hoses since I had this trouble.

Sunny has posted some good information about Dinoflagellate over here:
