That’s true about the polyfil, it is more malleable to fit into the whole space better. I did just add IPSF’s wonder mud and live sand activator to increase bio diversity.That is one good thing about the poly fill you can stuff and manipulate it into the cracks that the water might be flowing by. Didn’t you just add a bunch of bacterial mud of stuff from a recent order? Maybe that will help.
