Dino ID please

[Yoonsuk Choi]

Can I assume they are Ostreopsis?

My tank is 6 months old, and it had been in good condition until last month.
Although the nutrient level was low(PO4 zero, NO3 Zero), but acros were good and there was no dino or other things.
But I decided to increase the nutrient level, in order to make the deep color instead of pastel tone color of my acros.
So I started dosing Ammonia(0.1ppm a day) and Phosphates(0.01ppm a day).
Then boom, Dino kicked in.
So now I am battling with Dinos.
What I do is
1. manual removal(once a week when water change)
2. keeping the nutrient level high(NO3 ~10ppm, PO4 0.03~0.08ppm)
3. keeping temp under 77F
4. dumping Microbacter 7 daily.
5. Stop dosing AF -NP Pro (but still dosing Bio-S and Pro Bio-S daily)
6. Keeping Redsea roller fillter even if it only takes 4 or 5 days change cycle(daily usage is 4m ~ 6m)

That is ostreopsis dinos. Most of the things on your list are good. Not sure about keeping temps under 77f?

The best way to get rid of them is with a UV sterilizer plumbed into the display. Also stop doing water changes until they are gone. Run fresh carbon media because they are toxic.
