Wall Hammer help

I have a new wall hammer thats about 1 week old.. It is shape of an "H".. Anyway, half of it is dying... One half is half way opened and the other is apparently dieing.. Do I just let it go and see if the healthy side makes it or do I cut the half off thats dying.. The hermits, cleaners shrimp and snails are all over the dieing half...

What to do?? I have 2 other hammer coral, 2 large frag spawns and a large torch that are all doing great....

 

what`kind of lighting?

what kind of flow is he in?

does the dead part look like anything? brown jelly? torn tissue ?

maybe a pic if you can

LED'S, is low in tank and has low to mod flow, the dead part shows a the skeleton and decaying tissue. Not really brown but will let wife determine that as I am color blind. The dying part also has tissue coming loose. The wife just said it did possibly have browning in the dying part for her memory. I will pot pics shortly.

Alk is pretty low, also they like a lot of light and moderate flow IME. How long has it taken to deteriorate?

 

I have been struggling with low alk.. I have been doing weekly 20-25% water changes.. What should fresh slaft water alk be? I am going to check mine before I add to tank for water change.. What is likely cause of it staying so low?

I can add lore light and flow but its within 2 inches of a frogspawn that is growing like a maniac.. Its a branching frogspawn that has developed 22 small heads over last 2.5 months...

 

Are you having a lot of coral growth? If so, that may be why it's consistently low. You might need to dose Alk.

To verify, is you alk. in dkh or meq/l?

 

Is in dkh.. I knew its low and I have been trying to fget it up.. Started dosing reef fusion 2 part system 1.5 week ago to help... Yes most all of my corals are growing like crazy.. Most anyone who comes over states how much bigger my corals get weekly... Not sure normal growth rate but I honestly dont think I would want them to grow any faster

 

I am pretty sure frogspawns and hammers do not sting and hurt/kill each other like they do to other unrelated corals but if the half that is dyeing on the hammer is the half that is exposed to the frogspawn and the half that is doing ok is t he half that isnt that would be my first guess.

I am pretty sure if a head of a coral is dying it is usually best to remove that head before it spreads to another and eventually takes down the whole colony but I will let the experts chime in here

 

It sounds like the dying brown area you are describing it could be RTN. You can use airline tubing to siphon off the dying/necrotic tissue and then you may want to give the coral a dip in an Iodine solution like Pro Coral cure to help prevent the spread of the RTN. The dip helps prevent the introduction of flat worms in your tank and also acts as an antiseptic and hopefully prevent/treat tissue necrosis in damaged corals.
