Not cloudy in tank and disperses, but like I’ve seen it sit on top of my marine pure block in my sump and stay there for a while. I just know based on the calculator that I should have moved it at least 1 dkh in last 24 hours and it hasn’t moved a lickIf it collects on the bottom and stays there, its a problem.
If it seems to disappear as it disperses in the tank, its normal.
Cloudy water throughout the tank is also a problem.
