cyano

[darlar76]

I have something growing on my LR. I believe that it is Cyano. It is a very dark red carpet that started next to my featherduster. If it is cyanobacteria, will it do alot of harm to my tank.

Also, on my other LR there is some more stuff growing. It's greenish and yellowish, kinda reminds me of mouldy bread. Should I get gid of it.

No Pics, sorry

I think it's more that it's ugly than harmful. It can be harmful in reef tanks since it will grow over everything including your corals.

The greenish yellow stuff I have no idea. It could be sponge, coral or an algae. Unfortunately without a pic that's the best I can offer.

darlar76, what are your water parameters? If you update "my info" with your tank size/equip/critters, we might be able to help, better.
If it is cyano, you should see bubbles and it will spread like wildfire.

Roka64 is right. If your water N03 and N04 are high you will suffer the plague of the red carpet on everything! Water changes water changes and more water changes.
