Brown algae on Acro tips??

[Gwitness]

I have a bunch of Acros in my 180 and some of them get burned tips and grow algae on them and then some of the Acros that are right next to the ones with burned tips are perfectly fine??? My parameters are very stable...phosphates 0...nitrates 10....alk 8.0....ca 440....mg 1250....temp 78-80...I know I have enough flow also...I have an mp40, rw15 and rw 20 power head.....only other thing I can think of is lights and my lights are radion gen 3 pros and two t5 bulbs....the radions max out at 45% and are 8 inches above water...I didn't think it was the lights because if it was wouldn't it burn all my Acros tips?? Any help or ideas would be great....thanks!!!!

In my experience if the tips are burning something is not right with your alkalinity and PH. I keep a birds nest coral as a detector in the back corner, they show signs before most corals will, but usually it has to do with PH or ALK.... IMO...good lcuk

 

[Gwitness]

Thanks for the response....and of course my bird nest is fine! Haha....my alk doesn't sway more than .5 ever...as long as alk is in line that means ph is also right? And if it is ph or alk why would it not affect all of my Acros??

Does it look like Dino?

 

[Gwitness]

No it is literally on the tips that are burned only and looks just like regular old algae...not cyano or hair or Dino's

In my experience, and this.could have nothing to do with yours I'm just trying to help, some acros are heartier than others, weather some are aquacultured or wild grown, or some could be 5 or 6 generations into aquaculture where others that are 1 or 2 generations into aquaculture will be less tolerant to changes in conditions. Ive had some things completely die while others look great and no problems with parameters, were they bought as frags or colonies? Also, it could also do with the flow and lighting the coral needs. I have a piece of aquacultured strawberry shortcake acro it s
doesnt seem happy anywhere yet, i lost a little branch and have no idea why. All parameters are great

Well that's a good point .....most of the stuff that is having issues is the corals that are grown out in the ocean and then shipped out, I think maricultured ...and those are the ones really having issues .....my lights are radion gen 3 pros and schedule is same as someone who has a great sps tank so I know that is fine (intensity is 45%) as for flow I thought I had enough...I have an mp40 and a jebao rw15 and rw20....are maricultured supposed to be harder to keep or something?

I'm so sorry to hear that. Hope you can find answer soon. Bump this post to the top, wish more helpful people can see this.

What's your fish stock (what fish do you have)? Any carbon dosing?

 

[Gwitness]

I do not carbon dose at all and I have 14 fish...3 tangs and the rest are smaller fish like goby and Anthias

That is what the Acros will do....hopefully pics will show enough

i had similar things happen to my acros cuz of GFO , you should look in to that , if your PO4 is reading 0 then that could be the problem , some acros like a little more PO4 then others . If you just changed ur GfO media then that could be it , dropping Po4 to fast can case burn tips for acros

 

[Gwitness]

That is a good idea....I don't run any Gfo or anything on my tank yet, but I did drop my phosphates down a bunch over about a month by water changes...maybe that could be it and I took it out too fast...but then again some of the corals doing it were added after I dropped the phosphates....if phosphates were at 0 that would burn the tips? I know you are supposed to keep them around 0.03 but i didn't too low would burn the tips like that

 

[Stoneyman]

Same thing is happening to me. I have all these different suspects its driving me nuts. What are we suppose to do with the burnt browned out tips? Break them off? Will colony grow over it?

cut them off so the recover will be faster

you can keep them lower then that , but when you drop it too fast it stresses the coral .
