Angry or dying Acro?

[snyderman99]

Hey everyone!

I’m having some trouble with this acro. I noticed recently it started having drown spot on it. 2 weeks ago my parameters were super low (nitrate 6.9 phosphate 0.02. They are usually not this low) so I’m thinking that the coral just got defensive. When I realized I started to raise the nutrients again but the browning started after raising the nutrients again. I also have been going up on my lighting slowly but know for a fact it is not in as high PAR as it was kept when I got it. Does anyone know what I should do? Should I just not touch anything and leave it alone? It is also in good flow so I know it’s not detritus build up or anything like that. New to acro and just trying to keep him happy. All of my other acro actually look happy or the same as they have been.

The picture is a bit fuzzy and its hard to see, if you can take a more clear focused picture it will help. But to me it looks like the branches are dead and the brown stuff is algae growing on the dead parts.

This is the best I got

Algae growing on parts of a coral usually means those sections are dead or dying, I would reccomend dipping the coral to see if that will save it

I was doing some research online. Do you think it could possibly be coral burn? Strange to only happen to one coral though. I got this and another at the same time and the other seems to be fine the one I got with it is to the left of it. Next to the torch coral

I don't know if its stn or burnt tips, but the tips look dead and the brown looks like algae to me, sorry! I'm just intermediate level with acro's, hope someone more knowledgeable can help, good luck.

It’s weird because it’s happening seemingly overnight. I was doing research again and saw the it could be from to much or too little light. It could also be from overfeeding. I just started feeding my corals and I know that the light could be higher for the acro. Maybe it’s a build up of zooxanthellae? Like I said I’m new to this so I really am unsure and not sure what to do

Clip the dead parts off and dip in coral rx or something similar. That's what I do and usually they will make it. Burt tips can be a couple of things. Too high par, high phosphates, or flow issues.

Acropora Brown Tips and STN

Anyone have any thoughts on causes/remedies for this condition? The acros will do great for a month or two then start developing brown tips and then STN. 187 gallon tank is 16 months old. Alk steady at 8 dKh. Aquaforest 1, 2, 3 dosing regime. T5/LED hybrid lighting with 420 par 6" down at...

My coral looks like the one here but no one seems to have an answer in the thread. I feel like if it was flow other corals around it would also be unhappy and I’m fairly confident the flow is good. So I’m stumped if it’s actually dead branches or not. My PAR at the top of my tank is around 200 so I don’t think it’s that. Maybe I went up too fast? I’ve mostly been increasing the blue and violet and not white though. I’m going to check my phosphates again tomorrow but last time I checked (Monday) it was 0.15. Like I said I’m new to acro so any tips would help. Would you still cut off the parts?

I took a video to try to show the flow of that part of the tank. Do you think I need more? I think you’re right the coral is dying :(

Had to tell on your flow but looks ok. If I had to guess you had a parameter swing that the acro didn't like. You can keep it as is but if the dead tissue grows then I would cut right unter the living tissue and dip.

Keeping acro is the hardest part of this hobby. You need everything stable with good, random flow. Tank age also plays a big role. Older the tank the more stable your numbers. If you want to dip your feet into acros then I would start with a birdsnest acro. They are the easiest. Once you have that coral growing like crazy then move to a milie acro. And so on and so on.
