Hi All
I was going to wait some more days to post this. But in lieu of an excellent discussion we have today on this thread ( http://www.reefsanctuary.com/forums...s-definition-what-low-high-nutrient-tank.html ) that finished in some comments on coral color, I decided to do the posting.
Going to the point. In the last weeks (~3 weeks) I started to notice a slight change of this bird nest, from its classical green color to this yellow color.
At the beginning I started to think on bleaching. But I discarded that because when this coral was in my Nano tank at less than 4-5 inches of the LEDs that where at 70% I did not see any change in color (a picture can be seen in the first posting of my thread here :http://www.reefsanctuary.com/forums...niels-tank-upgrade-rsm-250-a.html#post1251540 , the coral is the one on the medium/left over the rock).
Since I moved it to the new tank (RSM250 of the thread) it has been healthy and growing. Still is growing, just the color change is picking my attention.
Not that I dislike the new color, It is very pretty, but I would like to share it and see if anyone would like to comment.
Some tank data:
RSM 250 all standard with the exception of a refugium on the media rack.
- Lights : Red Sea T5 Spec PLUS one 36" TrueLumen Pro actinic LED strip + one 36" Ecoxotic Actinic/Purple LED strip + one 24" Trulumen Pro actinic LED strip
- Water: Petco Natural Ocean Water
- Dosing: Ca and Alk
- PO4: 0.18-0.16 ppm
-Ca: 417 ppm
- Alk: 10 dKh
- Mg: Lats time I measured it (1 month ago) was on the classical range. Because it is always like that I do measure it very sporadically.
-Water Changes: ~10-15% every week.
Here is the picture. The upper picture is from today and the other is from around ~3 months (Grrr photobucket do not keep the date of the upload. I estimate it due to his growth and the coral growth around him - see picture and you will notice the growth-).
This is today's full picture
Any comments ?
What do you think ?
Could be that is really bleaching ?
Thanks
Daniel
