I have HOB power filters running on my tank.
A: Aquaclear 70
B: Marineland Penguin 200

I want to use Purigen as the last piece of media to touch the water as it leaves the filter. How should I arrange this in my filters? In the aquaclear I have sponge at the bottom, filter floss next, and biomax at the top. In my Penguin 200 I have the C size filter in the back (Water goes through it first), and then filter floss in front of it (2nd piece of media to have water go through it). How can I get the most water to flow through the Purigen in these two filters?
 
Just realized one treats 100 gallons. I'm getting two. One to replace when exhausted. I don't trust the bleach recharge. So under the biomax then. Thank you.
