PhosGuard Placement?

[NanaReefer]

I'm new to sumps. Wondering where best to place a bag of PhosGuard?

Return chamber?

I place mine in an area of higher flow which is next to the compartment where the skimmer is and happens to be in the return section.

+1!

I've got 3 chambers. Overflow/skimmer, center refugium and return. So I should put it in with the skimmer & overflow?

I have a bag sitting just past the pre-filter in the overflow.

Doesn't really matter as long as it gets lots of flow. I put my purigen, chemipure, and phosguard in the baffles after my skimmer
