Cyano breakout during/the end of Cycle

[04V10]

Yep. Looks like I have dinos.... Damn!

I'm going to cover the thing with cardboard and not let any light in for 72H. I don't have any livestock in the tank, so I don't have to worry about that. I don't even have carbon in the system yet as it was still cycling. I'll add the carbon to the HOB filter during blackout to help..

Any other suggestions let me know. Might keep it black until next week!

Oh and I'll add an airstone while doing this to keep the pH up.
