Hydnophora help.

[ingtar_shinowa]

im new to sps having recently placed a blue voodoo ~4-5" and a larger green hydnophora ~5-6" in my 55g reef tanks that is a few months old. I have good coraline growth coming in on the rocks and my glass lol. over the past couple days the tissue on the tips of the hydno have been receeding showing the white skeleton underneath. My acro looks great however, so I dont think its a water quality issue. My numbers are just a little low on Wednesday, using Seachem testkits they were:
SG 1.021
Temp 77.9
MG 1125
NO3 4 or less
PO4 none registering
ALK 2.0 Mel/Q
PH 8.3 (end of photoperiod)
Ca 350

So I dosed with Tech-M, Seachem Reef Carbonate, and Kent Marine Liquid Calcium and my levels right now are:
ALK 3.5
PH 8.1 (start of photoperiod)
Ca 400
MG ~1200

bump your MG up to at least 1350 and your SG to 1.025~1.026.

and technically hydnophora is LPS

same happend to hydno. i left it for dead on the bottom of my tank and forgot bout it .one day say a little speck of tissue on it figured id give it another chance. it made a huge come back and really stands out now.its bout 5" x 4" beautiful piece with awesome full expansion.cant belive it made it. good luck

Roor that bumbing up both! Also going to lower it in the tank, RC guys mentioned that it could be bleaching a bit which makes sense

here is a pic of the guy

that hydno looks fine. just keep stable params and bump up your SG and MG and feed some coral food and it will bounce back in a huge way

 

[ingtar_shinowa]

lol the camera doesnt show how much tissue has gone. I think its light more than anything because a patch of polyps on the base is fully extended and looks great. TIme will tell!

ALK 3.5... That is WAY low if that is alk in dkh. Need to slowly get that up to around 7 or 8 at least.

 

[ingtar_shinowa]

haha no mel/q

 

[Garage1217]

Just making sure I always kept mine in lower light / lower flow.

 

[ingtar_shinowa]

thanks for the warning anyway though. I DID freak out a bit my first test because I always see ALK in DkH too hahaha

 

[ingtar_shinowa]

this is a better pic after i figured out the macro function on my camera

as mentioned before get your s.g between 1.024 and 1.026 i believe that is def your problem,1.021 is to low

bump your MG up to at least 1350 and your SG to 1.025~1.026.

and technically hydnophora is LPS

though technically it is LPS, IMHO it require sps water quality. Year back my colony perished due to lack of water maintenance. You even have to push your Cal to at least 400pm and kh 2.4meq/l, especially you mentioned that your coralline algae had grown. Mind I tell you, how fast it will consume them and yet you have some sps! Pic attached the replaced colony with me a year back and been fragged few times. Happily with my param Cal 420ppm, Mg 1390ppm and 7.5dkh.

Sorry for hp pic quality.

i also have a hydnophora in my mixed reef but i keep mine in high light and high flow. made the neon green color come out more but they will zap the hell out of any other coral it touches

Technically, nothing is an LPS or SPS. These are terms made up by hobbyists. Hydnophora belongs to the same family (merulinidae) as other corals known as SPS.

I had this issue with hydno before. WHen I shot it with a turkey baster tissue would fall off. I used Iodine dips and 20 mg/l of chloramphenicol in a quarantine tank. Cured the problem in 3 days.

 

[ingtar_shinowa]

ok cool, think CoralRX would help? It has no iodine but i have no products to iodine with. Is there a thread you can point me to to pick stuff up at a pharmacy? Thanks for you time guys!
