What about beech (Fagus sp.) nutshells? The leaves of this tree is OK, but waht about the nutshells, maybe they are better than leaves, or worthless? I always see a lot of them while collecting the leaves. But still prefer the leaves. Just because I don’t know are they suitable for paro tanks as much as alder cones, oak or beech leaves.. :huh:
