Can anyone identify please

[Dinnerz]

Just wondering if anyone can help with identifying what I have growing here. (Dark brown spots)

Tank has almost done a 2 week cycle.

All my parameters are doing good and this has just started to grow on a couple of rocks and the sand, it started 4 days ago as 3 or 4 spots then rapidly grew to other rocks and the sand.

Just wondering if I should be concerned or if anything I can do to prevent further spreading and possibly eliminate it all.

Thanks

"Oh, those horrid age spots."
The tank is getting older and more diverse.
It's normal and it will probably get worse, based upon typical new tank trajectories.

Lol, you've just begun the algae adventure. Please scroll down to the section after "intermission ".

Thanks so not much to worry about just yet then I suppose?

I have been adding a coralline algae booster in the hope to get that growing but obviously that does take time but could that be causing this to grow?

Might be? I am not certain what the booster might contain but if it is nutrients for algae growth then it is likely contributing to what you are seeing.

If you're running lights this early on, I'd turn them off. When I cycle mine they'll be off for the first 3 months. The idea is to have beneficial bacteria EVERYWHERE to act as competition for space.

Great point, I thought I saw a Kenya tree so I was thinking the lights need to be on, but nope. Not yet..
