Hey guys. I battled Dino’s when I first set up the tank. And I’m afraid it might be back again.. after 7 months! Can anyone confirm?

I was thinking it was diatoms but I never seen diatoms under a microscope. I added some pvc piping submerged about 1.5 weeks ago so I thought it might be leeching some silicates.
 
These do not look like ostreopsis they don’t have a sharp tip. It also looks like they have two cells within themselves. Weird
 
Prorocentrum?

 
Prorocentrum?


you actually might be right. At first when I looked at the photo it didnt look like the cells match. But when looking at the second video it looks like it.

 
A little update on my battle, About 4 weeks ago, I purchased a microscope, and it turned outi had Prorocentrum Dino's. ID HERE Since then did the following steps,

I do want to point out that I did add a ATS Scrubber, and i am harvesting every two weeks. Before changing anything drastically, I performed a 3 day black out, I kept my ATS scrubber on 24/7 and that was the only light source Dino's had. My theory was that it would hopefully favor the flow and light in the ATS.

- stopped daily WC
- I had a 24W AquaUV running 24/7. I purchased an ADDITIONAL 24W, and plumbed it into my sump, How i am running it is, Return pump > UV > Chiller > UV > SUMP.
- in the AM before lights turn on I dose 4ML of po4, ( raises it approx. .04 )
- Feed regularly, ( that means im feeding about 4 cubes of frozen a day + pellets 3x a day.
- Dosed MB7 for 2 weeks straight, The bottle ran out so I stopped using it.
-added tigger pods 2x bottles
-added 40lbs of established rock from a buddy that was breaking down is tank (approx. 4 year old rock )
-removed 30lbs of liferock arches
-ran only BLUE lighting for 4 hours a day. ramping up slowly and adding whites to the mix. ( 2 week after the blackout )
-Today i started to have my T5 on for 4 hours a day
- Run my skimmate DRY
- kept my glass DIRTY. I didnt clean it till today. from the weeks and weeks of battling them.
-Dose expired PHYTOFEAST to the tank once a week


The 3 day black out wiped out most of it. Probably because they were dormant. and this was 4 weeks ago.

A quick reminder, that during the two weeks time of blackout and changing light settings. I kept the tank covered every night and day so when the lights arent on the tank is pitch black.

Last Monday I went ahead and added some ALGAEBARN package pods. 4 bottles of it. ( not sure how much that is )

This morning I had a chance to take out the microscope again and take a gander at the sand, none that I can see. only microscopic living creatures scattering around.



Video from today If you click the link, That video is from today, The only brown patches I see is underneath the rockwork/arches. I have not checked with a microscope if they are infact Dino's or not. But it is weird that they prefer shaded areas.

My tank has been set up for about 7 months now. and im starting to see an explosion of coralline algae. and finally a TON OF PODS in my sump.

Hope this helps anyone trying to fight them. When my Dino's exploded it was within a day that all my sand was covered in it. Its been a few weeks now that none has shown up. So im trying to be optimistic that im winning the fight.
