Hmmm... From the photo online, it looks black leh.. Hehe...
CaribSea Hawaiian black is very big grain... Average biggest grain is 3mm..
CaribSea Indo black sand is mixture of white and black sand...
So still consider which to get...
Yeah, Was told they flash only when stressed, but the blue is nice too...
I will just wait for next shipment, but I normally dun go on shipment days... So a bit difficult to see them.. LOL..
