Thank you Oxy.
As I said several times, this tank with less than a year is still evolving and finding the equilibrium.
The other, same bird nest in the corner of the tank, is taking the hit too and the purple beside it in the picture above, is losing color.
Nitrates are high: 16 ppm with red sea test and PO4 still high: 0.16 ppm with hanna and red sea kit.
Started NOPOX treatment at half dose, just in case.
Since I added Chemipure elite and purigen zoas started to recess. I added them in Thanksgiving. I am taken them out at a bag per week. Only left one (of 2) chemipure.
My last fight will be to control the N and P , if I do not win it, I will give up with a full SPS tank. And will switch to a mixed one. Much more easy. I am traveling almost all the,weeks for 3-4 days and started to be difficult to be in details.
I stopped several years ago to chasse numbers and these P and N levels will be my last chase. My 14 G biocube is doing it only with W/C and it was 2 years ago I did measured parameters. No skimmer neither and us a beautiful mix tank with Acro/ SPS /LPS and softies.
Will see.........
Cheers
Daniel
