Yellow gold spots on my white dry rock

[Angel Fink]

Set up new 55 gallon salt water tank with dry rock. I have yellow spots all over, is this normal?

Welcome to Reef2Reef!!

Pictures would help us see what's going on. It could be an algea film growing on the rocks. Which would be very normal with dry rock early on.

Hello and welcome
In new tanks,usually first thing to show = diatoms so look up diatoms and see if same/ similar but pictures sure would be helpful

What is that!! A R2R guide to common new tank hitchhikers.

One of the greatest things about starting a reef tank is getting your live rock in and admiring all the diversity within it. The rock comes to life different creatures. This is a guide that I, along with a very well known critter identifier @KJ , have put together for the new reefer on what...

Good luck and enjoy

Welcome to R2R! Without pictures I can't help much, but that sounds like the beginnings of a diatom bloom. It is normal, and a sign that your tank is maturing.

Welcome to R2R! It sounds like diatoms but a white-light photo will help.

Welcome.

If you are growing gold, please send me your methods! Alchemists have been trying to do this for years. Reefs generally get diatoms, as other have mentioned but eventually those white rocks will have lots of stuff grow on them!

How long has the tank been wet?

Welcome to R2R, the community needs pics and your water parameters. The more info you provide the better the information you'll receive.

Welcome! We need more background. Is the rock in the tank filled with water? How long has the tank been up for? Did you turn on the lights? Or are you referring to spots on completely dry/sterile rock?

We need pictures really could be diatoms though.

And welcome!
