how to place chemical filtration when using a sump?

About to take the leap and hook up a hob overflow and sump/refuge on my 50g

I've always had a aquaclear HOB filter on it where I put carbon/chemipure/purigen. I'll be losing the HOB now to make room for the overflow but I'm wondering how I can still use chemical filtration with a sump? Water should be flowing through the pouches correct? So just tossing them in there won't likely do much good... could I make use of the baffle area or is that ruining the purpose of them. Should I put the aquaclear filter on the sump?

Thanks, sorry about all the questions I'm sure I'll have a zillion more soon :)

You can throw bags of carbon in the sump, this is known as using it "passively". You can also use a Phosban Reactor to run carbon. You can hang it on your sump and use a small pump to feed it or feed it off of your main pump.


PS

We are having a GB on Reactors and Pumps and Carbon as we speak (hint hint) :)

I use a small canister filter (Fluval 205) on the sump. It is made for a 40 gallon tank, so the flow is about 180 GPH which is perfect for something like Carbon or Phosbas (Phosban reactors like to be in the 150-200 range to not tumble the media). I have no foam on any type and load up the 3 trays with whatever I need. Currently 1 tray is carbon, 1 tray is RowaPhos and 1 try is empty. The empty tray is ocassional used with Nitrate removed.

This makes it simpler to not have to tune another connection from the main pump.

Tuning the old phosban reactors from the ball valvles sucked and as something got added ot taken away from the sump or flow, more tuning had to be done.

The canister filter just for the sump solved the problem. The hardest part was convincing myself that I need to get the SMALLEST one, but the most powerful one.

(Ever notice, that cell phones are the only thing that men wiil admit to having smaller of ;D)
