unfortunately I dont have pictures because after few tried I took off everything to start from scratch.
I started with a 2mm ekowool, it was easy to work with and I put around 1.5inch on each side (2 tips) inside the tank, when the middle is well coiled (tightly) on the top.
I tried cotton, it was too messy and thin,
Than I tried using one roll of mesh (the one that came with the atty), but it changed the resistance drastically, so I wasnt sure how to coil it without interrupt the coil resistance.
