Stagnant stock tank water grows algae, breeds mosquitoes and turns livestock away from the trough. A pump to drain and refill the tank, or an aerator to keep the surface moving, solves most of it. Where there is no power at the tank, a solar or 12V setup does the same job without a long extension cord.
This guide is built from manufacturer specs, listing details and buyer ratings, not from our own bench tests. Prices and ratings were checked on Amazon on November 6, 2026, and they change often. Match the product to your tank size and power source before you buy.
Our Top Picks at a Glance
A thermoplastic submersible pump with a 10-foot cord. It moves up to 1800 gallons per hour, so it empties a trough fast for cleaning. It has more than 26,000 Amazon ratings at 4.6 stars, which is a deep review base for a pump in this price range.
A plug-in air pump and air stone in one unit, sold in sizes for ponds up to 1000, 1800 and 3000 gallons. The 1000-gallon size covers most single stock tanks. It is rated 4.4 stars across more than 900 ratings.
A small solar-powered air pump for places with no outlet. It suits a single trough. Expect less output than a plug-in unit and weaker performance on short, cloudy winter days. It is rated 4.0 stars across nearly 400 ratings.

Pumps: Drain, Clean and Refill
Superior Pump 91250 1800 GPH Submersible Utility Pump
The most useful pump for a stock tank owner is the one that makes cleaning easy. A submersible utility pump drops into the trough and pushes the water out through a garden hose. At 1800 gallons per hour, a 100-gallon tank empties in a few minutes. The 10-foot cord means you need an outlet nearby, so use a GFCI outlet and keep the plug dry. It is not meant for continuous duty in the tank.

RecPro 12V Self-Priming Water Pump
This is a diaphragm pump sold as an RV water pump, with a 3 GPM flow rate. Ranchers use pumps like it to move water from a barrel or cistern to a trough from a 12V battery, which can be charged by a solar panel. It is a supply pump, not a submersible. Add a float valve at the trough and an inline filter. Check the pump’s pressure switch and wiring before you run it off a battery.

Aerators: Keep the Water Moving
AquaMiracle All-in-One Pond Aerator
This is a compact unit with the air pump, tubing and air stone in one package. The 1000-gallon size is a sensible match for a 100 to 300 gallon trough. It plugs into a standard outlet and runs quietly, so it suits a barn or shop outlet. The air stone will clog with mineral scale over time, so rinse it every few weeks.

PondAir 2 Complete Aeration Kit
PondAir 2 is a complete kit that adds tubing and diffusers for a larger or deeper tank. It costs about $20 more than the AquaMiracle and has a longer track record, with more than 2,300 ratings at 4.5 stars.

Frabill Aqua-Life 50-Gallon Dual-Output 12V Aerator
A 12V aerator that runs from a battery, so it works at a remote trough with a small solar panel and a charge controller. It is built for bait and fish tanks, so use it for small troughs and keep it out of reach of animals.

HIBLOW HP-80 Linear Air Pump
Overbuilt for a single trough, but it makes sense for a large stock pond or a row of tanks on one air line. It is a linear diaphragm air pump that is also used for septic systems, with a rating of 4.7 stars across more than 2,400 ratings. At about $264 it only pays off at scale.

Solar Water Pumps and Aerators
4W Solar Pond Aerator
A small solar panel and air pump for a trough with no power. At about $28 it is the cheapest way to keep surface water moving. It will not keep a tank ice-free in winter, and it works best in sunny weather. We would treat it as a summer algae control tool.

For a true solar-powered water supply, pair the RecPro 12V pump above with a 12V battery, a charge controller and a solar panel sized to the pump’s draw. Size the system for your longest cloudy stretch, not the average day.
How to Choose
- Tank size: a trough under 300 gallons needs a small aerator. A stock pond needs a linear air pump and tubing.
- Power: use a plug-in unit if there is an outlet within cord reach. Use a 12V or solar unit for remote tanks.
- Winter: an aerator moves water but does not stop it freezing. For freezing weather, use a tank heater instead.
- Safety: use GFCI outlets and keep cords out of animals’ reach.
Final Verdict
For most small ranches, buy the Superior Pump 91250 for cleaning and refilling, and add the AquaMiracle All-in-One aerator if the tank has an outlet. For a remote tank, start with the 4W solar aerator for summer, or build a 12V system around the RecPro pump.
