Airmax Stock Tank Defense — 24 Tabs
Airmax Stock Tank Defense tablets use natural beneficial bacteria and enzymes designed for stock tanks, water troughs, and livestock containers. They help break down organic debris, maintaining clear water for drinking. The tablets are easy to use—drop one dissolvable tablet into a tank (up to 150 gallons) every 1–2 weeks, or with a water change. Suitable for farm, ranch, barn, agriculture, and equestrian operations, this treatment supports ongoing tank hygiene without aggressive chemical residues.

Airmax Stock Tank Defense — 6 Tabs
This version of Stock Tank Defense provides the same natural bacteria-based approach as the 24-tab option, suitable for regular maintenance of stock tanks and water troughs. It helps ensure drinking water remains clear and free of organic debris, with recommended use aligned to tank size and seasonal temperatures (above 50°F). It is a practical choice for ongoing farm and equestrian operations requiring simple, non-chemical upkeep.
30 Gallon Stackable Emergency Water Storage Tank
This 30-gallon emergency tank is designed for compact storage and vertical stacking, making it ideal for limited spaces in homes, apartments, or RVs. It is constructed from BPA-free, lead-free rotationally molded polyethylene, specifically intended for long-term potable water storage. The stackable design helps maximize storage capacity in tight environments, while ensuring water remains accessible for family needs during emergencies.
Buying Guide: Key Considerations for Farm Water Tanks
Capacity vs. space: Evaluate daily water needs against available storage area. Larger tanks store more water but require more space and weight handling during transport.
Material and durability: Polyethylene tanks with UV inhibitors resist sun exposure and reducing cracking or fading. Look for chemical resistance if tank contents may include cleaning agents or agricultural solutions.
Fittings and compatibility: Ensure the tank has a compatible cap size, drain type, and hose port. A 2-inch drain and 3/4-inch garden-hose port streamline controlled emptying and refilling.
Portability and mounting: For field use, consider tanks with handles, shoulder straps, or hitching options for trucks, tractors, or trailers. Flat bottoms and ribbed structures aid stability during transport and stacking.
Maintenance and treatment: For livestock water, choose products with easy maintenance features and consider water treatment options like beneficial bacteria tablets to reduce debris and improve clarity.
Environment and safety: UV resistance helps extend tank life in outdoor settings. Choose BPA-free materials for potable use and verify that the tank’s contents meet local safety standards for drinking water when stored long term.
