Sps getting brown tips ?

[Piece of reef]

Hey guys, so i bought my first acropora about 5 or 6 days ago from a local reefer closing down his tank. It called dallas acro here in australia, similar to the green slimer.

Its my first sps, i dipped in melafix before adding to the tank,
And it has been getting abit of brown algae or zooxanthellae? Or something on it

Not sure if its normal or if ive done something incorrect, or if its AEFW, would love some advice and hopefully a solution

Params are, as of 2 days ago

Temp - 78 steady
Ph - 8.0 steady
Nitrate - 5 steady
Phosphate- 0.1 fluctuates abit between 0.05- 0.1
Alk - 7.8 fluctuates abit between 7.5- 8.0
Calcium - 430 steady but trying to raise slowly to 450
Mag - 1350 steady

Water levels look ok. Is it slimy crap stuck to it or is it the coral itself browning out? What’s your lighting system?

Definitely stuck to it,

Dinos in the tank?

 

[ryanjohn1]

Is it stuck to exposed skeleton of coral?

No dinos, abit of gha nothing crazy, have chaeto growing, and yeh its to exposed skeleton looks like

 

[ryanjohn1]

exposed skeleton is a bad sign. It probably is Dino’s on the skeleton. Good chance you’re gonna loose that one.

What causes it?

Id like to add, the coral isnt a small frag, its a decent size

 

[ryanjohn1]

Exposed skeleton means it lost flesh. One way or another. Dinos attached to skeleton. Could have been from the move or could have been something in tank it came from or your tank.

 

[ryanjohn1]

Is it on one branch or a bunch of branches?

Its on 3 banches out of the 9

 

[ryanjohn1]

No fun there. Something caused flesh loss.

How is your flow?

Alge will not grow on healthy SPS.

If u can frag the dead tissue. I do this when I prune back my sps. If the coral is healthy it will heal and grow. Stop the necrosis

Once I rid or reduced the number of Dino's in my tank (via removed all sand), my SPS coral no longer became covered on the tip with brown algae. My SPS's look amazing once I removed the sand bed.
