We already brought you the product specifications on the SHARK Cone Skimmer from JNS Aquaria. And in it we mentioned their new Quick-Precise adjusting valve that allows the user to accurately changed the water level in the protein skimmer’s body, allowing for a more dry or more wet skimmate production. Well, now we’ve got a video of it. The user in the video shows just how easy this skimmer is to adjust, as well as how well it responds to the adjustment. Definitely an interesting addition to the protein skimmer world.
