There does not need to be much control, it's simply clay if you get
unscented etc.
I've used it with great success back in the mid to late 1990's.
Clay is the cheapest absorbant around so that's why it's been used to
clean up oil spills, cat waste etc.

The water absorption is normal. The cloudiness tends to go away after a
day or 2.
I do not suggest adding Jobes, you can, but if they pull uprooted
plants, you can plan on an algae bloom soon afetr unless a large water
change is done asap.
