After seeing 4 different colonies of pulsing xenia...well..not pulse, I decided to pick up a Salifert Iodine test. This thing was a bit more involved then I was hoping for, but the initial results are:

Iodide: 0.01
Iodate: 0 (no color change)
Iodiate/Iodine: 0 (no color change)

I've been using 3 to 4 drops of Lugol's weekly, and it seems this isn't enough.

What do you other reefers use as a supplement? I suppose I could just increase the amount/frequency of Lugol's dosage, but the label doesn't mention how much product will increase the numbers by x amount (if that makes any sense).

Other parameters are:

Alk:3.2 meq/l
Ph: 8.2
Ca: 410
Mg: 1180
temp: 78-80.5
No3: ~10

Any help would be appreciated. I've never been able to get this stuff to pulse no matter what amount of flow or light they are subjected to.
