Red Algae

[vtec525]

Hello reefers,
My nano tank is about few months old. I had diatom algae for few weeks and now gone but theres red algae on sand bed last 8-9 days. I think its cyan?

In any case, how do i rid of this ugly mess;Vomit? Safe way for my zoas and fish.

Thanks

Cyano is typically present due to an imbalance in the no3/po4 nutrients. Check this levels and make eye they are within reason and maintain those levels for the long term. For short term, siphon out the cyano as much a possible.
