What's Happening With My Green Staghorn

[TheGreenStag]

Hey guys so I am a bit inquisitive to know what is going on in my tank. I have a 150G mixed reef mostly SPS. Lately I have seen my green staghorn coral tips skin was cleaned out completely. I thought it's new growth tips. Well that wasn't the case. Apparently after couple of days It wasn't looking healthy and some brown stuff started growing on it. I have another frag of Bali green staghorn and it's also going through the same thing. Today I gave both of them a revive dip. I have attached couple of pics of the Bali frag where u can see the skin of the coral is wiped out to clean white and the stuff that came out after dip.. All my other sps are you great except green staghorn. have a look and let me know what can cause this.

Out of curiosity any frogspawn in the tank?

If the tissue if flaking off pretty quickly it is RTN. I would check your nutrient level. In the first picture near the fingers I see green and this is normally a boring algae that tunnels through the calcium skeleton and can irritate the tissue and cause it to flake off. I would cut that portion off as well as any other damages tissue. Make sure to cut into healthy tissue when you are fraging but use a lighter to sterilize the cutters after each cut. So you don't infect the healthy tissue. Also check for corals stinging or irritating the coral.

It looks to me like something could be munching on it.

Thanks Kman...Nutrients could be a possible issue lately i have tried to increase my nutrients as my No3 and PO4 were registering a constant 0 and 0.02ppm respectively. However strage enough i saw my cyano growing in my refugium ONLY along with Chaeto.. I am getting chaeto to grow at a very fast rate so much so that i am harvesting every 2 weeks almost a dense baseball size ball. This tells me there is nutrients and causing rtn. I stopped dosing Nopox a month ao since my nutrients were registering low constantly. I did cut the damaged pieces on my large colony and gave a revive dip. I think i will restart dosing nopox (2 ml a day) again to try and bring nutrients in check...Thanks for chiming in...

Well it's just odd that one time I had burn spots on a large green slimer, it turned out to be little spores from the frogspawn. The slimer was sticky and where the little bits landed they burned away the tissue just like that. Not saying that's what it is, but I ended up finding a bit in the very center of a burn one time. Now if the clownfish are chewing away bits of the frogspawn I'm careful to remove the floating bits. Just a thought...

Interesting...wow this hobby has so much to teach us...every day is a different day in the ocean...lol...i am going to start dosing nopox again because a wise man said it never make abrupt changes in this hobby and my bad i should have reduced the dosing rather than stop dosing it completely...hoping to bring the slimer back fingers crossed...i was more worried about any pests but i know thats not the case at all else i others would be in the same category..

this is a great tip...funny part is when i tested my nutrients this weekend my No3 showed anywhere between 2-5ppm (very faint pink color on salifert test kit) and my Po4 on ULR Henna showed 0.018 however i am getting crazy growth of cheato and NOW SOME CYANO in my refugium which points towards enough nutrient being in there...

yup macro algaes definitely throw off your readings because you are reading the nutrients not being exported by the algae.

very true +1 to this statement...i am going to start nopox dosing regimen again as i use to about a month ago and keep an eye on the stag..if it shows improvement we know the culprit...

I like to keep it simple and use as little products as possible. It is cheaper and easier to troubleshoot. I would do weekly water changes for the next month or so. For the first two I would do a good size one like 20% or so. Just add the water back slowly to allow the corals to adapt. Then do smaller ones after that.

True..i will give that a try. Thanks guys awesome forum...i posted this in R2R, reefcentral, GTAA but most help and advise i got is from this forum. THEFRAGTANK rocks....

There are many approaches to fixing things. You just need to make sure you don't complicate things when it is not needed. I myself like to keep it simple.
