Orange Digitata

[pdiehm]

I was given an orange digitata frag a few weeks ago, and unbeknownst to me at the time, was battling dinoflagellates. 3 days of darkness appears to have cured that.

Anyhow, The digitata frag polyps stopped coming out, and the color started to fade from a deep orange to now a very pale orange.

It's my first SPS, and I know it's not doing well, what I don't know is why, and I did expect it to die off to be honest, but now I need to find out why it is dying.

These are my parameters at last test (last thursday).

Salinity: 35 ppt
Nitrate: 10ppm
PO4: .02
Alkalinity: 9.5
Calcium: 430
Magnesium: 1350
pH: 8.2

Tank: Coralife Biocube 29

For lighting, I have an AquaIllumination Prime, running at 100% 20k (B, DB, UV, V at 100%, G, R, W at 17%). My BTA appears to be doing very well and enjoying the light.

For Flow, I have a Jebao RW-4 running at speed 4, pulsing, a Koralia Nano 240, and the coralife return pump.

For placement, I placed it on the sand for a week, and then moved it half up the rocks, and eventually on the top of the rocks under the Prime light.

I think the flow and lighting are good enough...but then again, I don't know much about corals, and am very very close to just having 2 FOWLR tanks at this point.

As far as I know, the montipora digitata are pretty hardy. My orange is the slowest growing of all my digi's however. I'd give it some time, and not move it. I think movement can be the enemy when it comes to any SPS, as they'll acclimate to a variety of conditions. Just have to let them.

I'd say keep it in low to medium light and medium flow and give it time. They're pretty hardy usually.

If it's your first coral it would be a good idea to see if you have too much light.

Buy ($15) or borrow a lux meter to get an objective reading.

Medium light would be around 40,000 lux.

Anything from around 20,000 up should be perfectly acceptable. Around 80,000+ lux is "direct sunlight" and should be way more than needed.
