LOBSTER TANK The lobster tank provides an environment that closely simulates the natural ocean waters in which lobsters thrive. As a result, Stark Lobster Tanks keep more pounds of lobsters alive for a longer period than any other closed system available today.

– Stark Lobster Tank Operating Instructions BREAK-IN PERIOD: One of the key components of the Stark Filtration System is the biological filter bed. During the initial installation and start-up process, the Activated Sand for the sand filter will be introduced into the system. This will commence the process of building up the level bacteria necessary for a solid biological filter.

The filtration system will not work properly if the level of water is below this mark. Pre-mix salt water as follows: Add 1 lb. (16 oz.) of Stark Marine Crystals to 4 gallons of cold water. Mix well, and add slowly to tank.

The protein skimmer removes the foamy protein lobster waste products found in the water. Through this filtration process, the tank will lose water and the water level will drop.

WARRANTY: Stark provides a one-year warranty on all mechanical parts of the tank. During the term of the warranty, Stark will replace mechanical parts deemed to be defective from the manufacturing process at no cost. STARK Products Co., Inc.
If lobsters have been in cooler for more than 2 days, DO NOT put them into the tank. USE ONLY the proper size pre-cut exact fit Stark Filter Pads, Marine Salt Crystals and Carbon.

Stark) would we recommend a water change. If necessary, use salt water (1 lb salt to 4 gallons of water) to fill the tank. Stark ships a 1 lb jar of chlorAm-x, which is used for start-up to keep the ammonia level low until the biological system can handle the bio-load.
Mix in a bucket: 1 lb of Stark Marine Salt with 4 gallons of water, then pour into the tank. NOTE: Never add undissolved salt or a large amount of fresh water directly into the tank.
3) What do I do if lobsters start dying? Call Stark. One of our experienced technicians will work with you over the phone, or via video conferencing, to help resolve the issue as expeditiously as possible. If is determined that the issue cannot be resolved remotely, the Stark technician will make a service visit to resolve accordingly.
