It's a jar.
After being in and out of the hobby for years I thought, oh heck lets do a planted tank. But rather than buying loads of stuff lets do it small.

Plants- anubias, dwarf pennyworth, salvinia natans, some hairgrass

Co2 - none, diluted seachem excel when I can remember

Fert - super diluted orchid fert when I can remember

Water change - er.....

Bio load - 4 ember tetras, 1 ramshorn snail and a few mts

I realise there is no picture... I am doing this from my phone. Will link later
