SPS growing or dying ???

[happyvalley]

Can someone tell me whether the white tips are growth or recession ? I am new at this and embarrassingly I do not know. If someone could Identify the coral that would be nice too !

For what its worth, the lighting is a 400watt metal halide about two feet above the coral. Soft corals appear fine and so do the fish.

The coral has been in this tank for around 3 weeks, and I bought this piece at a frag swap at the end of April. The tank has only had corals in it for a month or so, but the tank has been up for months.

Salinity 1.026
PH 8.1
Alk 8.3
Calcium 500

It looks like you've got a healthy, growing birds nest of some kind. Color and size of the photo make it pretty hard to identify what birds nest.

Agreed it looks like she's doing good and growing. Nice colony you got ther

[biggles]

Pretty sure you have healthy and growing Seriatopora caliendrum (http://coral.aims.gov.au/factsheet.jsp?speciesCode=0341)

That seri looks like it's pink with light green growing tips, what do you see with your eyes mate.

that coral Looks very healthy . Your calcium is way too high it should be between410 and 420 that's a good range not 500. Make some more changes and bring the calcium level down your coral will appreciate it.

Honestly don't mess with the calcium, you may start a problem that didn't exist, IMO only. I suppose if using dosing pumps drop back a little but being a self admitted newb and one of your only hard corals, you'll get more and it will lower. Plus with accuracy in the tests and test procedures/endpoint interpretations....

[Wazzel]

That is growth. I agree that your calcium is a bit on the high side. Retest to see if you had a bad test. If you are dosing cut way back or stop until you get to 420 +/-.

[footballdude2k3]

+1 to agreeing that it just looks like healthy growth

[markalot]

Calcium is fine IMO, I'm guessing you use a high calc salt mix?

The birds nest looks very healthy and in me experience these types grow fast. :)

[Reefvet]

Shhhhhhhh, don't tell your coral that your CA tests high. It'll never know the difference and it will continue to grow just like it's been doing. :uhoh3:

Seriously, ignore the guys who think you need to lower the CA. It'll get there on it's own as your coral grows. Why disturb success.

Agree with Reefvet on this one. If it's growing nicely then why mess with it.
