My Tank Thread
Hi all. I assumed I had Dino’s as this was what they appeared to be with there stringy snot and bubbles on the end initially. However, the reddish brown stains still plague my sand bed.
Recently, I’ve noticed that the red/brown stuff got on a rock, and it looked matted like cyano. I’ve heard it’s quite possible to have both in some cases.
It may very well be that most or if not all the Dino’s are gone but still have remaining cyano. It’s just some reefer said it still looks like Dino’s during one of my Reddit posts and I just assumed it was still this. Either way, it’s still a nutrients issue.
Sorry if I have wasted anyone’s time.
But I still have some questions. If nutrients make them worse, and i starve my tank to get rid of them (only thing that has ever made progress) won’t they just come back if the nutrients are raised again? Seems like a losing battle lol.
I’m just thinking if I starve the bacteria out, that just starves the beneficial bacteria right? So to my basic understanding, that would be a waste of time.
I am not sure how, that logically, raising the nutrients for good algae will do anything but fuel the cyano/dinos. Which will out compete the good algae. But if starve the tank, nothing will grow lol.
Seems to me I am at a stale mate unless someone has other information or can explain what I am not understanding.
To my understanding, I need enough nutrients to grow good algae. But my only logical thought on this would be that there has to be more good algae in the tank than cyano or Dino’s, that the majority competes against the minority. Would physical removal of the Dino’s be my only option to create this environment?
My recommendation for cyano is manual removal, organic reduction, and higher flow. Cyano is about the only organism in a reef tank that can get N from N2 in the air, making nutrient reduction a seemingly poor for it.
