Hammer coral not looking good

[ahill25]

So I've had this hammer for about 6 months and just this past week, it has shrivled up and I can start to see the skeleton. What could've caused this and is it dying? This is one of the oldest corals I have and don't want to lose it!

ph: 8.4
ammonia: 0
nitrite: 0
nitrate: 5.0
phosphates: .25

Lighting and/or flow are the usual suspects.

What are your Alk, Ca, Mg levels?

What are your Alk, Ca, Mg levels?

I currently don't have an alk or mg test. My Ca is around 420.

You don't perchance have a hungry coral beauty angelfish? Mine appreciated appreciated 40$ snacks.

I usually have my lights on around 8 hrs. I've adjusted to about 7 hours and turned up the flow.

I do not..

Hmm. Hope it makes it. Try moving it around and or get your water tested at an lfs that can test the elements you can't.

you would be wise to purchase the other test. Alk being the most important. Nitrates of 0 is a problem - i shoot for 2-5 in my sps dominate system

So I found a KH test kit and after researching I found that it's the same as alk. Is that true? If so, it read around 10kh.

I currently don't have an alk or mg test. My Ca is around 420.

I highly recommend testing Alk (KH) and Mg as those are very important to monitor with LPS and SPS. Swings in Alk can cause a lot of stress to your coral. If you have had it for 6 months and it’s suddenly not looking well I would suspect it’s nutrient/element related. Your phosphates are also a little low
