What’s wrong with my tank?

[jj.man]

What’s wrong with my tank? I have brown spots showing up on my rock and my golden hammer looks like it’s dying after 2 weeks of having it. My other corals also aren’t opening up.

What's that behind the hammer in the first photo? A mushroom or a blob of slime? If slime, may be brown jelly. Can you get a photo with more light?

 

[Mr. Mojo Rising]

The brown spots look like the beginning of diatoms, normal in a new tank.

Tank is too new for coral. Let it run with fish only for 6 months

 

[The_Paradox]

Tank looks fine, how about water chemistry?

How old is the tank? Looks too new for corals.

 

[shakacuz]

tank looks very new.

water parameters? lighting? how old is the tank? what fish/inverts are in the tank (if any)?

edit: also, welcome aboard the r2r board. hello from PA!

I always wondered what that means. I have a 2x2’ frag tank that gets deep cleaned about once a year. Corals sit in a tote for a few hours then go right back into the tank. Never had an issue.

Show signs of starvation and instability.

Is your tank hooked to a mature system? A blanket statement like that doesn't give a full picture. Yes but do you bleach or acid wash the media/rocks.

Same, it know it sucks, but really need to give the tank some time to age.

My last tank was up for a few years and still had issues with some coral, even though everything seemed good.

No rocks, sump or sand, except small rubble and tiles the coral is on. Usually citric acid to clean depending how bad scum line and coralline is.

We need more info to help. Parameters sg, alk, calc, nitrate, phos, ammonia, lighting. RO/DI, temp, everything you can give us will help. How old is the tank? though I believe if you know what you are doing this is less of an issue. Water change schedule? What salt? Inhabitants?

So nothing to the rubble

I don’t know any of my stuff. I just got started a few weeks ago but I know my salinity is at a 1.025.

4 weeks

You need to get test kits or have your water tested locally. Otherwise any feed back is just a guess.

 

[Dburr1014]

At 4 weeks out of your initial cycle, your system is unstable.
You absolutely need test kits. Alkalinity, calcium, nitrate and phosphate are the first 4 you need.
Fish before coral. Fish poop feed coral. Your coral are starving.
