Need help identifying type of algae

[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

Looks like early stage cyano bacteria. I noticed your tank looks bright and cyano loves light
Turn whites off for 3-5 days, blow the surfaces loose with a turkey baster and net up loose matter
Add 1.5ml of liquid bacteria per 10 gallons during the day
At night, add 1ml of 3% hydrogen peroxide per 10 gallons for 5 days
Day 6 you can turn whites on but at a lower intensity
