Hammer dying?

[Davisc1293]

This hammer looked great for a couple weeks and is slowly closing up more and more. It seems to come out a little the first few hours of light then looks like this the rest of the day

Have you checked trace elements and complete parameters with an ICP test?

Do you feed your coral?

The photo shows a very shaded area.

 

[Davisc1293]

I have not done an ICP but I do feed occasionally and add amino acids every other day or so.

That looks like a wall hammer, which can be difficult to keep. Are you dosing anything outside of alk and calc and aminos? Too much flow can be an issue. Also, large fluctuations in alk can irritate it. I have one and it is doing well, but my tank is pretty stable and I keep it up against a rock structure.

Well your numbers seem ok as long as you have a little phosphate so that leaves lights or flow or possibly trace elements as the source of the hammers retraction. Have you got par numbers for your tank? What kind of wave pumps do you use for flow? Hammers just need low flow and maybe 100 par at most.

I just turned the lights down a few % and moved it to a lower flow area hopefully it will improve.

You can always RX dip it also in case there is a pest.

Wall hammer are hard. How matured is your tank??

Why are they considered hard compared to branching? I have both and both are doing well.

For one....when they go bad, you can't just cut off a head. The whole thing starts to go downhill. They are more sensitive and more prone to brown jelly. I have both kinds too and my wall hammer been through a lot...but it takes time for them to get acclimated to our system

Yes I'm aware that you can't cut off diseased heads buy not really sure why they would be more susceptible to problems? My walls seem to be growing better then my branching hammers.

Do not dip - at least yet- This is recession and not disease. Recession comes from stress :
too high of flow
Too much or too little light
Calcium below 380

Get coral off sand and elevate to at least 3" off botttom
Take UV to 60%

Sounds great. I don’t see any skeleton showing. It is just ticked off right now. UV does seem high. The good think about euphilya (yes i spell wrong ever tIme) is they will respond quickly if it is happy. Relocate as mentioned and see if it responds. If you start to see skeleton than there is concern.

If you put it near a rock and in low flow for awhile that should help. I have a wall hammer wedged in low flow against a rock and it does really well. Your numbers don't look bad. Maybe turn down your lights just a little bit and see if that helps as well.

I would guess flow if it try’s opening in the morning when your flow is low and closes later than I would move to a low area

My flow varies 24/7 and is not low specifically in the morning.

It could be too much light then. How long is your light on?

 

[Davisc1293]

I work weird hours so my lights are on from 430 PM - 2 AM with a 30 min ramp
