Sure! I just got my results back today which was stunning and right in time.
After I dosed Copper, Cobalt and Silver I sent a test out a week later to see how much they dropped from the math according to my dosing. At the time of the sample I did notice some white tips and reduced growth as before prior I started testing and adding controlled traces.
Well, I thought I screwed on Iodine but again my Barium levels were down to almost nothing. All other parameter were nice as expected and are good in shape, even Iodine.
So this dang low Barium (measure 2microgram/L), I figured out and as an isolated causes more trouble than I originally expected!
Definitely a trace element to watch out for.
It is know to be part of the calcification process and coral bring Barium deep into the coral, but apparently if almost depleted it causes white tips and reduces growth as well.
From the 2 last tests I know my depletion and will weekly dose this element and do a correction over the next few days. I should see improved growth asap if the theory is right ;-)
