Tanky adds large, nostalgic, multiblock tanks. Comes in two variants - iron tanks and steel tanks. Should be compatible with all pipe mods, please report if its not!
To construct a tank, place Tank Controller in middle and then build a symmetrical cuboid out of Tank Wall or Tank Glass (you can use both in any combination) with air in middle. Max height for tanks is 24, max radius is 9 (19 blocks wide). You can't mix multiple materials and if tank isn't formed properly it will have red blocks. If you want to expand the tank you can break any block other than the controller. If you break the controller, you will lose fluid stored inside of it!
