I just witnessed my live rock squirt out this white liquid with FORCE!! The best way I can explain it is, it was like if you loaded up a syringe with a white milk cream and put it in the tank and pressed the plunger. It was enough to make it look like I just dosed calcium. Imagine an octopus you have seen on the nature channel expel that black liquid in a defense situation, it was like that but white?????? Has any one seen this???
