Heat Pack

A single-use chemical heat pack included with temperature-sensitive livestock shipments during cold weather -- maintaining a safe temperature inside the shipping box throughout transit.

Temperature Protection in Cold Weather Activates on Exposure to Air Maintains Safe Transit Temperature Included with Cold-Weather Orders Single-Use Protects Shrimp, Snails and Plants

A Heat Pack is a single-use air-activated chemical heat pack included with shipments of temperature-sensitive livestock and plants when ambient temperatures along the shipping route would otherwise expose animals to cold stress, temperature shock, or mortality during transit. Shrimp, snails, and aquatic plants all have lower temperature thresholds below which their physiological function is impaired -- and sealed shipping bags inside cardboard boxes can drop to near-ambient temperature within hours of packing when outdoor temperatures are cold. The heat pack generates sustained heat through an exothermic chemical reaction that begins on exposure to air and continues for the expected transit duration, maintaining the interior of the shipping box at a temperature above the cold-stress threshold for the livestock inside. It is selected or omitted at packing based on current and forecast temperatures along the shipping route at the time of dispatch.

Transit Temperature Protection

Air-activated exothermic reaction -- begins working immediately on pack opening -- the heat pack is sealed in an airtight outer wrapper before packing. When the outer wrapper is removed at packing, the pack is exposed to air and the exothermic chemical reaction begins generating heat immediately. The pack is then placed inside the shipping box with the livestock before sealing. No activation by the customer is required. Maintains safe temperature for the expected transit duration -- the heat output is calibrated to maintain a safe internal box temperature for the transit duration expected at the time of packing. The pack does not maintain an ideal temperature -- it prevents temperature from dropping below the critical cold-stress threshold, keeping the livestock in a survivable range throughout transit rather than an optimal one. Selected based on forecast temperatures at time of packing -- whether a heat pack is included is determined at packing based on current conditions, forecast temperatures along the expected route, and the cold tolerance of the specific livestock or plants being shipped. Shipments dispatched during warm periods do not need heat pack protection; cold-weather or winter shipments do. Single-use -- cannot be recharged or reused -- unlike the reusable ice pack, heat packs are single-use -- the chemical reaction that generates heat is not reversible. The pack arrives spent after transit and can be disposed of with standard household waste once the exothermic reaction has fully completed and the pack is cool. Included at no additional charge when conditions require it -- the heat pack is a standard packaging inclusion for cold-weather shipments and is not charged separately. It is part of the base packaging commitment for orders that require temperature protection to arrive safely.

Policies & Disclaimers

Check fit, included parts and intended use, with practical guidance for aquarium accessories and shipping supplies.

Size, fit & what is included

Check the selected option, dimensions and quantity in the listing before ordering. A net’s shape, a dish’s footprint, a filter’s height and a holder’s opening can matter as much as the aquarium’s stated volume. Measure the space where the item will be used, including access around lids, equipment and hardscape.

Photographs show the product and examples of its use. Plants, moss, food, livestock, airline, pumps and other display items are included only when the listing explicitly says they are. A stand or holder is not automatically supplied with the item it holds.

Compare the actual selection with your intended setup. Do not assume a similar-looking accessory fits another brand, tubing size or attachment. If a needed measurement or included component is not stated, ask before purchasing rather than estimating from a photograph.

Before installation

Inspect the item and its packaging on arrival. Check visible surfaces, seams, mesh, connectors and any supplied parts before putting it into the aquarium. If you find a crack, damaged edge, missing part or suspected mismatch, photograph it and contact us before use.

Follow the product’s instructions for assembly, rinsing and installation. Avoid household soap, scented cleaners and unverified chemical treatments on aquarium-contact surfaces. Do not assume every material tolerates boiling, a dishwasher or an abrasive cleaning tool.

Use equipment only for its stated purpose and within any stated limits. Where electrical equipment is part of your setup, follow its manufacturer’s electrical and water-safety instructions. Do not treat an accessory’s aquarium use as a statement that every connected component is submersible.

Sponge filters: airflow & establishing filtration

An air-driven sponge filter needs an appropriate air supply and connections to operate. Check the listing for exactly which parts are included rather than assuming an air pump, airline or valve comes with the filter. Assemble the system according to its instructions and confirm that air and water are moving as intended.

Choose placement and airflow that suit the animals while keeping the filter accessible for maintenance. A new sponge provides a surface for beneficial bacteria, but it is not automatically a mature biological filter. Continue monitoring water quality while filtration becomes established.

Filter performance depends on the complete setup, stocking and maintenance. A size recommendation is not a guarantee that every aquarium of that volume can support the same number of animals. Keep established biological filtration functioning when making changes and follow the filter’s cleaning guidance.

Nets & temporary holding accessories

Choose mesh, opening and depth appropriate to the animals you intend to handle. Check for damaged mesh or exposed edges before use. Move animals calmly and avoid trapping delicate legs, antennae or fins against the rim or surrounding equipment.

A net or holding accessory is a handling tool, not a complete aquarium or long-term housing system. Consider water movement, temperature, escape routes and the time an animal remains confined. Do not assume a floating or attached accessory is secure without checking it in your setup.

Keep handling tools clean and consider separate tools for quarantine and established aquariums. Follow material-specific cleaning guidance and prevent unwanted transfer of water or debris between tanks.

Feeding dishes, stands & holders

Place feeding dishes on a stable surface where the animals can reach them and where uneaten food can be removed. A dish helps keep food in a visible area; it does not remove the need to check feeding amounts or clean up excess food.

Inspect glass or ceramic items for cracks and chipped edges before installation and during maintenance. Avoid forceful contact with rocks, aquarium glass or other hard objects. A holder should fit the intended item without forcing or stressing either part.

For lollie stands and similar feeding holders, confirm the opening and positioning suit the food being used. Support the item securely and check that the arrangement does not block access or create an unsuitable trap for small animals.

Plant weights, rings, moss supports & hides

Plant weights and rings are accessories, not live plants. They do not qualify for the Buy 2 Get 1 Free plant offer. Check what the listing includes before assuming moss or another plant is supplied with a tower or support.

Secure plants without crushing stems or covering growing points that need to remain exposed. Position floating rings so they do not obstruct equipment or concentrate plants where water movement is unsuitable. Recheck attachments as plants grow.

Choose hide openings and internal spaces for the animals’ size and behavior. Position hides and towers securely, with access for inspection and cleaning. An accessory can provide shelter, but it does not guarantee that territorial animals will coexist or that predators cannot reach smaller tankmates.

Heat & ice packs: shipping support

Shipping packs help moderate conditions inside a properly packed shipment. They are not aquarium heaters or chillers, and they do not guarantee a fixed box temperature, a particular carrier delivery time or livestock survival. Use them only as intended and follow the specific pack’s handling instructions.

Our ice pack typically provides cooling for about 24–48 hours, depending on conditions. That is an approximate cooling period, not a promise that it will arrive frozen or remain cold throughout every journey. Ambient heat, transit duration, insulation and package contents affect how quickly it warms.

A thawed ice pack on arrival does not by itself show that it provided no cooling during transit. Heat-pack duration likewise describes the particular product’s intended performance under suitable conditions, not guaranteed protection from every temperature extreme. Keep pack contents separate from aquarium water and livestock.

Review our Shipping Information for packing and weather guidance. Adding a pack does not replace the shipping requirements that apply to live animals or plants, or change the existing Live Arrival Guarantee.

Cleaning, maintenance & wear

Inspect accessories periodically for buildup, weakened attachments, damaged mesh, cracks or loose parts. Clean according to the product’s materials and instructions, and check that the item is still positioned safely afterward.

Suction, airflow and other functions can change with placement, buildup and wear. Investigate an unexpected change rather than compensating by forcing a connection or modifying the item. If you suspect a fault, stop using it where continued operation could damage the setup and contact us with the details.

No universal service life, replacement schedule or new warranty is stated here. Any product-specific instructions or documented warranty should be checked for that exact item. These maintenance notes do not create additional return exclusions.

Package problems, incorrect items & questions

Inspect your equipment or supplies and their packaging on arrival. If the package is torn, wet, leaking, incorrectly labeled or appears to contain the wrong item or quantity, contact support@superiorshrimpaquatics.com promptly with your order number and clear photos. Include the label, the affected product and packaging so we can understand the concern.

Keep the original packaging and avoid using a product that appears contaminated or compromised while you ask for advice. This is practical documentation guidance, not a new claim deadline or a promise of a particular resolution. A routine unopened return and a report that an item arrived damaged or incorrect are different concerns; tell us which applies.

Existing return terms & exchanges

Equipment and supplies are dry goods under our Return Policy. Ordinary returns require prior written authorization and unused, unopened items in their original sealed packaging. Contact us from the email address on your order before sending anything back, and consult the linked policy for its request window and complete eligibility requirements.

The buyer pays return shipping and safe packaging costs. Original shipping charges are non-refundable, and there is no restocking fee. Returned items must arrive in their original condition for inspection.

Approved refunds are processed within 3 business days after receipt and inspection, to the original payment method for the eligible item value. In-store exchanges are available for eligible items with prior written authorization. Promotional, free and final-sale items are subject to the exclusions in the full policy.

Shipping & mixed orders

These products ship as dry goods under our existing shipping practices. Review the delivery address, selected quantity and variant before checkout. Dispatch and delivery timing depend on fulfillment, stock and the selected service; a carrier transit estimate is not a guaranteed ship date.

If your order also includes live animals or plants, review their shipping requirements separately. Adding equipment or supplies does not remove the requirements that apply to the live items in that order.

Live Arrival Guarantee scope

The existing Live Arrival Guarantee covers live animals and aquatic plants. It excludes food, botanicals and other dry goods. The livestock reporting window and bonus-animal rules are not equipment warranties or supply guarantees. For an issue with this item, contact us and refer to the Return Policy above.
