Rather than messing about with small bits of them I wound up fitting 6 in the chamber then just filled in the gaps with some spare ehfisubstrate pro.



Less bypass overall and still exorbitant surface area for a 7 gallon tank I'd think. I just fit a 100ml Purigen on top of that as a final stage and the first (lower) chamber has some ceramic rings topped with the stock sponge for mechanical.
