So, i was going to introduce my tank and ideas here, since i'm new, but there is something bothering me at my tank so i'm going for this first. The reason about this post is to see if anyone have experinced something like this before or know what kind of organism is that...

Basically several months ago, i had a massive tragedy caused by a sea cucumber on my tank and right after my tank was getting better, i had reddish algae issues, wich you guys call cyano. I did lots of syphoning and daily-dosing nitrification bacteria for arround 2/3 weeks and that pretty much worked, that algae vanished and my tank was pretty much a new one.
But since mid-May i noticed a new organism burried at the bottom of the sand layer, making it's way to the top, so i started to weelkly-dosing nitrification bacteria, it pretty much stopped its growth, so i'm going for daily-dosing again. But i wonder what that thing is, i can't syphon it cause it is burried 5 cm beneath the sand with some parts a little above.. also its not getting any good or direct light source.. Some weeks after the reddish algae issue was solved, i added a Clownfish and 2 bad-shaped tiny BTAs that my LFS gave me, they were really bad-shaped but i wonder if its associated with this red-pinkish organism. My tank was set up 11 months ago but since that tragedy, i lost almost everything, but my tank right now is better than before with good parameters aside from Nitrate (arround 15) and pretty stable. This organism is my only problem right now..


I'm posting 2 pics of the part this red-pinkish organism is more concentrated

No lie, I think this is just cyano. Maybe someone will chime in with a handy identification guide, because appearances are not always reliable. But my tank looked like that when it broke with cyano. But after my cyano cleared I got a dino outbreak so that is a possibility. I read that the cyano to dino outbreak is real common.

You just reminded me from my last '''cyano''' outbreak.. i took a few notes back then. It is from the phylum Rhodophyta, basically all the red and pinkish algae from the ocean (includes all encrusting coralline alge from well mature tanks). About ''dino''flagellates, they are mostly phytoplanktonic organisms, at reef tanks they aren't harmful, since they are food source for zooplankton.
But thanks dude!! You made me remind all that stuff!!
