Help with my Hammer please!


New member
Can anyone tell me what maybe happening to my hammer? And is there any treatment for it. It has been doing wonderful until the day before last. I noticed that the middle head was not openning like the rest of the heads. Then today I came home and found this! I have not noticed any slime, brown jelly looking substance or anything.

Water paramaters are as follows:
temp 78
ammo 0
nitrate 0
nitrite 0
po4 0
alk 6.4 dkh 2.40
calc 410
ph 8.2
salinity 1.024
magnesium 1170

Thank you for any help!

Sounds like brown jelly disease. I do know it will take down the entire coral if it's not addressed. I'm not an expert in treatment of this so hopefully someone else can give you some advise.

I can tell you that your alkalinity and magnesium are both low. Safe ranges for alk is 7-11 dkh or 2.5-4.0 meq/l. Your mag should be between 1250-1350ppm. Bring the alk up with some baking soda. You can use epsom salt or Kent Tech-M to bring up the mag.

Please use this calculator when dosing these chemicals. ;)
