Phosban reactor question

[penguinsix]

I just got a phosban reactor for my 10g because I can't rid myself of diatoms, I am using rodi with little to no tds. I don't want to run all 150 grams of phosban at once because that is 15 times as much as I should use. I was thinking of only using like 10-20ish grams at a time in the reactor. Now my question is would this be too little in the reactor to create too much motion causing the phosban to turn to dust, or should I just run all 150 grams and hope for the best?

I just dump half the jar of phosban in the bag it comes with and toss it in the back of my 12 gallon tank and it works great. I don't think you can put too much in, I think I would be more worried about it breaking up if you put to little in the reactor.
