Possibilities:
1 PH, Alk, phosphate
ph 8, Alk 7.6, phosphate 0 (no nuisance algae)
2 Too much light, not enough turbulent flow.
Too much light: I did forget to acclimate lights but it is positioned in partial shade and was looking happy and fully extended for 12 days under current light setting
Not enough flow: It is getting some indirect flow from the mp10 and return spout and it did have constant (gentle) movement. Does it need more aggressive flow?
3 Chemical warfare between softies. Leathers in particular.
It is a little close to a stretching disco shroom and a candy cane coral, although I've never seen either them touch. Is that a concern?
Suggest:
Keep testing water.
Add quite a bit of carbon, see if that helps.
Check flow.
Spot feed.
Will keep testing, although results have been consistent. Suspect mg is faulty or for some strange reason I have super high mg.
Adding carbon.... given that nitrates are less than 2, is that a good idea? Any risks of doing so? If not, I'll run it
I have been spot feeding reef roids 2 days in a row now. Keep going?
Another observation: The only thing I have changed in my tank recently is to add a chaeto fuge basket to the secondary chamber, in addition to the chaeto I already have in the media basket thats in the overflow chamber. But I believe that shouldn't have a negative impact on anything.
