Some sort of algae?

So I recently set up a nano using water I had from my 75 gal. The parameters are fine with my ph at 8.2, ammonia 0, nitrite 0. My nitrates were not zero. But really low. But on the rocks close to the light they look orange. Not red. But orange. I used my finger and it rubs off but I have no idea what it is. Sound familiar to anyone? I have some corals and my recovering nem in there and they all look good so they don't seem to be affected by it

When I've seen bright orange in my tank it's been sponge or nuked macro algae (peroxide dip).

Orange (brown) diatoms? Where the rocks and sand new or also from the 75 (which im assuming was established)? If they are old and established its probably just nutrients that got released from moving. If its all new it sounds like new diatoms which is the process of cycle. That can (98%) be the sign of upcoming death for inhabitants. Happy to help but will need more info, and pics help the guessing. GL

I'll post pics in a bit. The rocks are new live rock from elite reef, new dry sand, and half established water and half salt water. My 75 has been established for 1.5 years.

I don't know if they sell rock ready to go, how long it was out and how much die off happened, ect... But it sounds like a cycle. Usually with any new component, including dry sand, time is needed to cycle and get the biodiversity needed to support the tank before live stock is put in. The water is great and all but won't be a miracle to a fast cycle, you need time, time and more time :)

Water changes, and let it do its thing. If the nem is already injured it could turn fast (for the worse) even in a small cycle, they love established stuff and struggle without it.

Ah. Maybe I'll move back some corals or something. That poor nem. I've been trying so hard to keep it going since my maroon clown is so aggressive. Poor guy. Thanks for the info though.

I was told I can do instant tank, same water just new sand and such, but I didn't think about the rocks. I did the instant when I swapped my 55 to a 75.

Could the cycle be at the end since only a few nitrates remain?

Possible, I moved established rock and sand into a new tank at one time and there was still a small and not devastating cycle which ended up with diatoms and a little hair algae, nothing compared to my first tanks full cycle. Moving rocks around in an established tank can still move nutrients to get diatoms, just monitor and be careful.

Definitely! Thanks for helping. The orange has decreased drastically and all corals still look good. I have my fingers crossed
