Hey everyone,


I have a bottomless 75 gallon saltwater aquarium with 2 hob filters. It has been set up for 2 months and ive already got coralline growth.


Have about 40 pounds of life rock (manmade rock never in the ocean never had anything dead on it)


Only 3 fish; 2 clowns and one lawnmower blenny.


5 trochus some baby trochus as well lol they did hatch in my tank though. About 6 hermits as well and 1 emerald.


Anyways, some of the rock (not all of them have this green algae on it, i will post a pic) and this one rock has some little air bubbles in the algae but i only recently noticed and i think it might be because my water level is low and lots of air bubbles are floating around (doing a water change today) i am just curious if you guys have any idea what it is? This algae has been on the rock for about a month and again i only noticed the air bubbles in them this morning. I get scared when i see air bubbles in algae because i immediately think of dinos. I do have some green spot and brown spot algae that im going to take care of and scrape off. I probably have a bit of a nutrient issue that i need to deal so ill slow feeding.


Does anyone know the type of algae?


And sorry i dont have params atm, i am not home currently and can check when i get home if you like. But my salinity and temp is perfect i know that for a fact. Ammonia is 0. That much i can speak on.


Thank you.

Without looking at it under a microscope I would actually say that it's likely diatoms from a new tank. Feel pretty certain that it's NOT cyano.
 
If your snails are doing well, probably not dinos.
