Quoted from NJGecko:My treasure cove powercut 1 has settled in the last few months. The top two layers I can shake back into mix, but there is a fine layer of something on the bottom that won't re-mix, so I'm not planning to use it.
Noticed that on mine as well this past weekend...I flipped the bottle over to see if it will settle back down. I was kinda bummed seeing that too
