Brown attack!

[moses reef]

Hey guys so within the last 24 hours I have had a huge amount of brown show up in the tank. it has small bubbles in it and a few strands of long seaweed looking growths but mostly just small brown spots on everything.. I put a small coral in the tank a week before from a weird fish store and decided tok throw it out 3 days later because it had some creepy crawlies on it but besides that it has been cycling for 2-21/2 months with perfect peramiters and now it' getting destroyed? I took the lights off for now to see if that will stop the growth. any ideas? thank you

Looks to just be diatoms in a newly set up tank, which is normal. What type of rock is that though? It seems very dense to be reef rock.

ehhhh...id probably get some new rock... is that lava rock? also is that some kind of putty to the left?

If you get a chance. Read this - https://www.reef2reef.com/threads/cycling-an-aquarium.306554/.. I would also read about dipping your corals. -

is that rock just from your yard? I would be careful with rock like that as there can be metals like copper in them which would make it impossible to keep coral. There's a reason why people use reef rock outside of aesthetics.

Be cautious when you get corals or any inhabitant as they may introduce things that are unwanted or impossible to rid of. QT is the best thing you can do to prevent future headaches.
As for what you have currently a person can guess diatoms or an introduction of unwanted dinoflagellates.

I'm getting live rock soon it was all I could afford. but what should I do for the diatoms?

I wouldn't do anything about the diatoms....just let them ride, they will pass. Depending on what that rock is made of, that might be contributing to the issue. If the tank is fully cycled, you can add a clean up crew which will help keep the tank clean during the ugly phases.
