What are your water parameters

I guess it is a dinoflagellate bloom. If you look into the tank with white light or just with the room light on, does it look brownish? If so it is a bloom of planktonic dinoflagellates. The only thing I know that helps is a UVC water clarifyer.

I have a good microscope and I have found dinoflagellates in clouded water. I have contacted a specialist for dinoflagellates on the Senckenberg Institute where I have got my scientific education. She confirmed that it is a dinoflagellate on the photograph. With a dinoflagellate bloom you will find no nutrients left.
What you are showing is a specific benthic dinoflagellate, most probably Prorocentrum lima. It is not a very typical dinoflagellate in being benthic. Most dinoflagellate species have a planktonic mode of living.

It is my profession for 30 years now and I have used UV to fight fish disease outbreaks. The UV unit just has to be a little bit stronger and you have to use it early in the outbreak. I used one 36 W UV unit each 1000 l.
