Hello,

I was wondering is someone would be able to Iidentify what is growing on my dry rock and if I should be aware of it. Anything to help fix it. Has rapidly been appearing.

Not an emergency and nothing to be worried about.

Part of starting up a new tank. Especially one with dry rock.

Give the tank time to mature, keep on top of nutrients, and it'll settle down in time.

What all is in the tank currently and what type of light are you using and on what kind of settings?

I would hold off on coral until you get your tank a little bit more mature and stable. It’ll most likely get worse before it gets better if you’re new to this hobby.

you are on a YEAR long journey... You can crash and burn quick if you go to fast.. But IF you stick with it.. Consistency is the basis.. even if you think you are being consistent....

go slow..

people on these boards are amazing... pick a method and stick to it.

Develop a routine.. test parameters even if you don't think you have to.

I would go low bio load for a long period of time... keep testing

Have a plan of what you want to add and then go forth.

...and keep asking

Diatoms
Super common in new reef because it feed off of the silicates that the new rock releases
After a couple weeks and water changes it’ll be gone

How new is the tank, and what are the occupants currently?

More than likely you can turn those down while letting the tank mature a little before you add more corals.

This is of no concern and not likely due to light but with everything looking new in the tank, source is likely silicates from the sand and/or rock. Some reefers find this matter ugly and want it gone.
Diatoms are a brown algae that typically appear in a reef tank that has just completed its cycle but they can also appear in an established reef tank. They can cover sand, rock, pumps, glass, you name it. Diatoms look ugly but in most cases they are harmless so the key is to not panic when they appear.
Diatoms feed mainly off of silicates but also consume dissolved organic compounds, phosphate and nitrates. Unfiltered tap water can contain silicates and is a good way to jump start a bloom if you use it to mix salt or to replace water that evaporated from the tank. The best way to prevent this from happening is to filter water through a RODI unit, although you can still get a diatom bloom when using RODI if the cartridge that removes silicates expires.
diatoms are typically harmless to a captive reef and can be beaten once their food source expires. Once you put the kibosh on the source, the outbreak should last a couple of weeks so just be patient and it will pass. For major outbreaks you may want to consider the three day blackout. Diatoms are easily wiped from the glass with a mag float, a turkey baster or a toothbrush can access other areas of the tank. Be prepared for them to re-establish themselves quickly, they are likely to be able to resettle and have exponential growth rates.
To prevent their return, practice good aquarium husbandry by doing regular water changes, keep the substrate clean, don’t overfeed the fish, ensure your skimmer is running at an optimal level and rinse out filter socks and sponges on a regular basis.
Some cleaner crew to help control it are : Cerith snails, Nerite snails and Trochus snails and also Astraea snails are effective at removing diatoms.
