It is heavier. I have my reactors comeing of my returns and it still doesn't tumble. Doesn't 't really have to. I got mine from drs. Foster and smith. 4# bucket for 50.00.
I agree with binford. phosgaurd is a heavier product and when running it in a reactor you dont need to worry about making it tumble, just adjust flow so that the water has decent contact time with the product in your reactor. Ive been using it on and off for the past five months and have had no negative side effects from using it.
