dinoflagelates

Brand New Aqua 8 Watt UV Sterilizer HOB for Tanks up to 70 Gallon. Never used, bought to remove Dinos $75

I have this stuff all over the sand. 5 nitrates, 0.19 phosphate. Any thoughts? Seems too heavy to effectively siphon out. Blows off the rocks and frags very easily. Goes away at night, comes back strong during the day. Orange picture has a yellow lense over the camera, bluer one does not.

I’m guessing this is Dino, what kind is it?

I’ve been trying to battle this ‘brown algae’ for quite a long time now. I’ve finally gotten a microscope to observe all the cells in my aquarium. Does the picture below look like Dino cells. The cells do move around and they go away at night and come back in the day. This makes me think it is...

Hey, I've been battling one or two of the three that I listed in the subject. Ive been trying to maintain nitrates at 2-5, and phosphate has been 0.05. I have been dosing neonitro and Microbacter7. Here's a video of the algae under the microscope:

Hey everyone, I have a pretty new tank setup. 100 gallon DT, 32 gallon sump. About 120ish total volume. I used cycled media from a previous tank to help get this one going, along with Dr Tims bacteria. It is about a month old. Here's my stock: 2 clowns, 1 royal gramma, 1 BTA, 1 Rock Nem, lps...

I have never come across this algae before. It looks sorta like dinos or diatoms. It is a brown hair that turns into a brownish white snot. It comes back fast after manual cleaning and leaves white fibers behind after I scrub. It grows on the rocks and glas and sand... but not on the corals...

so i think i have dinos in my sump or something like that i’ll post a few pictures and i know they aren’t the best pictures but they where the best i could get and i’ll also try to describe it it’s like a weird matt with bubbles in it or could this be something else

So ive got a pretty nasty dino outbreak in my 150 gal. They spread over the entire tank in less than 2 days from when i noticed them. I added vibrant this past monday at the reccomended dose and by thursday every acro i had has bleached white and died and my lps that were doing great ( torches...

Over the course of my 5 years in the saltwater side of the hobby, I have had my fair share of fights with everything from parasites, to nuisance dinoflagellates/cyano/algae. I can say my current system has been clean and running beautifully for awhile now, and I haven't had a run in with Dino in...

Hey everyone need help with UV flow rate because I know it’s vital for actually being affective. Currently I have a 9 gallon tank and bought and 8watt UV sterilizer. (Aqua brand) At what flow rate should my pump be? I don’t wanna go to fast but don’t understand the math for it

I have a reef tank that most likely has either brown diatoms or dinoflagellates growing on the gravel/sand. Tank is at least a year old. Tests indicate excellent water quality with the possible exception - API kit shows nitrate @ 0 & phosphate checker shows it @ 0.03 so maybe too low? meaning...
