Ok, so I'm pretty sure I have all three going on:
Here's my approach, I think:
So I've had Algae, Dinos and Cyano before (never at the same time). I want to hypothesize what went wrong though:
- Dinos - I see them on the sand and rocks, they go away at night. They seem to move if you blow them off, but never go away per se.
- Cyano - These are some local patches of pink stuff, which is relatively new
- Algae - Duh, it's there.
Here's my approach, I think:
- Remove as much algae as possible.
- Nuke the Dinos next. I've done this once, and I can do it again. I've used a H2O2 dose, blackout, etc. And it's worked for the Osteo.
- Come back to see what's left of the Cyano, and maybe hit it with Chemiclean again. I did this once, and it worked pretty well.
So I've had Algae, Dinos and Cyano before (never at the same time). I want to hypothesize what went wrong though:
- I think my GFO Reactor stopped absorbing...I didn't change the media as much as I should have. This lead to an increase in PO4.
- I didn't notice this, because algae was starting to grow slowly.
- Extra algae dropped my NO3 down to zero, which caused Dinos to resurface
- I boosted NO3 to fight the dinos, which then led to a cyano bloom.
