Bacteria or algae?

Plasticman85 · Jun 29, 2018

Hi guys first post here, I'm after some help with regards to what is growing on my rock. The tank is around 2 months old now using Marco rock and caribsea live sand. I am following the red sea program and dose 2ml nopox daily to the tank which is a reefer 250. The growths are an opaque white in colour and seem to come off the rock relatively easy
I have attached a pic of them excuse the quality!!

Welcome to Reef2Reef!

I would need to put it under a microscope to say for sure. There are algae and bacteria that can look similar to that.

When do you plan on adding your CuC?

Welcome to R2R! Looks like it could be the start of diatoms or cyano, which is perfectly normal for a new and maturing tank. You're going to see lots of colors and algea's come and go over the coming months

Hi guys thanks for the welcome! I do have some cuc in there at the moment just some nassarius snails and 2 strawberry conches I was told to hold of algae eating cuc such as trochus until I see signs of green algae and this stuff definitely isn't green!

It's not green algae, but it is CuC food if I'm guessing correctly. The conch's typically stay in the sand and the nassarius are detrivores. I'd add some true omnivores or herbivores and see if they go to town on this stuff.
