Is Cyano Bacteria toxic?

[OpenOcean33]

I was wondering if cyanobacteria is harmful to fish and coral in the reef tank? I grew cyano to outcompete dino, im now in the process of removing cyano but am now missing a fish that was perfectly healthy. I was wondering if it can be toxic as all other critters and coral are happy.

If you're missing a fish its not due to cyano. Cyano part of all new tanks and comes and goes. Not harmful to corals an inverts too.

Some species of Cyanobacteria are toxic and can be harmful to inverts and fish during blooms. However, presumably most species found in our tanks are not.

While some cyano is not an issue I wouldn’t use it to outcompete another problem...

Okay thanks for this, i as well would not use it as a first choice but my dinos were stubborn, no other option worked i tried it all from a to z for 8 months. Thank you for this information.

I've ran with higher nutrients before to overcome Dinos but I can't say I've ever heard of someone intentionally growing cyano. how exactly are you going about this?

I followed the main dino thread recomendations. So basically my type was coolia, which is a hard type to get rid of. I tried black outs, uv sterilizers, dino x, h202, you name it I tried it. Basically my tank was too clean I had no biodiversity. So I ran higher nutrients to allow other stuff to grow as well as adding copepods phytoplankton, beneficial bacteria to help compete with the dinos. So basically allowing my nutrients to raise and po4 allowed other alage to grow and what grew for me was some hair alage and cyano, I let it grow all over my tank and poof no more dinos, now I am lowering my nutrients down a bit to balance things out. Also my dinos were only on the sand and dino was able to grow over it and basically smother it. I hope this made sense if not run over to the di o thread I have it explained there as well as others. Also sorry I'm on mobile
