<b>The Shrimp Bubble</b> is a viable symbiotic aquatic shrimp ecosystem that self-sustains for an extended period of time. It contains 3 + 1 (free of c) live marine shrimp, live algae and microorganisms. All composing elements exist and interact with each other in an attractively designed, high quality clear glass bubble filled with filtered brackish water. No frequent water changes, No daily feeding, No water filtration. Just provide your Shrimp Bubble with indirect natural or artificial light and enjoy observing its gradual development.</p><p><b>How it works:</b> The algae use light and carbon dioxide to produce glucose and oxygen. The oxygen is liberated into the water and is used by the shrimp for breathing. The shrimp feed on algae and microorganisms and release waste and carbon dioxide into the water. Microorganisms feed on shrimp’s waste and brake it down into dissolved simple inorganic nutrients. The algae use the nutrients and the carbon dioxide for growth, thus closing the symbiotic cycle.</p><p>The greatest benefit of the semi-closed Shrimp Bubble Ecosystem is that one is able to remove the top and, every once in awhile feed the shrimp (shrimp food sold separately), or intervene to maintain good water quality if the system goes off balance, thus increasing the chances of a long term success. One may also recharge the Shrimp Bubble ecosystem by simply buying a live shrimp replacement kit.</p><p>The Shrimp Bubble Ecosystem Kit comes pre-assembled inside the clear glass bubble. You only need to transfer the shrimp from their transport container into the glass bubble.</p><p>Each Shrimp Bubble Ecosystem comes with a live arrival guarantee and a recharge policy.</p><p><b>NO INTERNATIONAL SHIPPING OR TRANSSHIPPING.</b> The Shrimp Bubble Kit cannot be shipped to Hawaii, APO/FPO addresses, Post Office Boxes, Puerto Rico, other U.S. Territories, shipped or transshipped Internationally. WARRANTY is VOID for all transshipments or any kind or reshipments.</p>
