I have the same problem, I will fallow the page. My Nitrate is 2, Phospate and silicate not visible with Salifert. TDS 2 in RO water. This is definitely not cyano or Dino. It only appears on the sand. I also have some green hair algea so I think there should be an excess element in the water that feeds both of them. And this is not going with WC. I will use Chemipure blue and fauna marine ultralife this week. I will share my experience.![]()
In my case at least I have no seaweed hair, and I've never had and I hope to continue.
If these products will serve us you comment, just that I have a problem and I live in Costa Rica and aquarium stores here do not bring almost nothing of those products and if I bring US, customs retain me.
