Large external canister with Indian Almond Leaf 'tea bags', ceramic and sponge media, flow restricted to replicate habitat conditions.
I used 80:20 RO and tap to provide soft and acidic water, enhanced by Aqua Soil, Oak leaves and Indian Almond leaf sachets installed in the filter. Although oak trees may not (I did research but could not find out for certain) exist in this region I considered some artistic licensing was appropriate. pH 6, KH 2, GH 3, temp 25C/77F.
