For the last 3 evenings after dosing the Ultra, I’ve noticed mesenterial filaments from my acro, something I’ve rarely witnessed before. From what I remember in coral biology classes, it can be a normal feeding reaction, or elsewhere in the spectrum, defensive. Given the circumstances and idea behind the products (i.e. feeding coral in low nutrient environment), I’m assuming (hoping) that it’s a feeding response. I’ll also assume, until I read around a little more, that what might be a defensive reaction in nature may be an indicator of stress in an aquarium.

I’ve been dosing the Ultra within the same 30 minutes – a drop of UltraBio, waiting 10 minutes, then .25 mL of UltraBak, and finally another 10 or so minutes before the UltraMin S. Since the weekend is here, I may see about spacing this out over the course of the day to see if I get the reaction from one of the Ultra products specifically.
