The Skimz Monzter ZM120 is an external zeo reactor designed for tanks up to 1000 liters that want to take advantage of an ultra low nutrient system (ULNS) in an external format.
The Skimz ZM120 is made from CNC machined parts and features dual chamber agitators to eliminate jams and reduce wear. It uses an adjustable feed pump (264-317 GPH) that pushes the water up and through the zeolite rocks.
It appears a PVC t-handle allows you to manually agitate the zeo to knock the mulm loose. Although this gets pretty solid reviews online, a few people have indicated you get some minor leaking at the top when you pump. Otherwise, people seem to like it.
The Skimz ZM120 measures in at 5.71 in. x 6.89 in. x 18.11 in. (145mm x 175mm x 460mm) with a body diameter of 4.72″ (120mm). It retails for around $200 USD.
