Algae help identify

[maryocean7]

Hello everyone

If anyone would be kind to help us in our new tank. We have had it for 2 months now and just last week this showed up. We can't get our hand on what it is exactly. We have caribsea Life Rock and life sand

Ammonia - 0
Nitrite - 0
Nitrate - 20ppm
Lights are on for 6 hours
We do have a small clean up crew
2 turbo snails
2 bumblebee
10 hermit crabs

It seems to come off easily with a turkey baster

The color of it almost looks like a rusty brown

Looks red/brown under blue light

Any help would be appreciated and advice on how to deal with it asap

Planning on doing a water change today

What are your phosphates?

What are your phosphates?

Just checked and they are at .10ppm

Looks like nothing to me. Maybe a small amount of diatom or brown cyano. Cyano can be brown. Green or red.

I agree with with @monkeyCmonkeyDo. With nitrates and phosphate being elevated. Can induce more algae. But it’s part of the normal cycle of a new tank.
