I'm facing a different issue. I have cyano due to my tank being exposed to the elements and absorbing mountains of insects. I also have a very hungry tank so cutting back on feeding is a problem.

Since dinos usually come with Cyano, I wonder if anyone has tried killing the cyano and measure the impact on dinos.

I've never used chemicals in my tank, except Lanthanum and that precipitated my Dino infestation... So I'm hesitant to go there again.

However, due to the excess cyano in my sump and the unknown black algae (cyano+??) in my DT, I'm using chemiclean to break up the cyano and the resulting red slime. I hope it'll break up the black algae too.

I'm turning my monster skimmer on 24/7 but at a low height to avoid overflows. I'm also turning my UV off... Here we go...
