Reliable Pumps for Happy Fish and Clear Water
Our pumps help circulate the water, which prevents stagnation and keeps oxygen levels high — essential for fish, plants, and overall water quality. In ponds with filters or waterfalls, the pump powers these features to remove debris and improve oxygen flow. Without proper circulation, algae can grow, harmful bacteria can build up, and fish may become stressed or sick.
Step 1.
Estimate your pond volume
To choose the right pump, it's important to first estimate your pond’s volume. Be sure to take depth measurements from a few spots to get a reliable average. If your pond has slopes, shelves, or irregular shapes, estimate conservatively or break it into sections. Knowing your pond’s volume helps you pick a pump that can circulate the water properly, especially if you have fish or a filtration system.
Step 2.
Calculate the lift and head
The height of the pond /water tank and under water are regarded as vertical distance. The distance between the pump and the pond is considered as horizontal distance, with these information, we can roughly calculate the head of the pump.
The pump can be also used for creating an aerating fountain. By pulling water from the pond’s bottom, it generates an upward flow that helps circulate the entire pond. resulting in fuller ponds, reduced algae growth, and healthier aquatic life.
Step 3.
Pair with right solar panel
The solar panel array should be 1.3 times the water pump's power, with voltage matching the pump's range.

What you need to know
How big is your pond?
How big is your pond?
Submersible Pump is recommended for small ponds which under 4000 gallons, especially for water circulation, Small fountains or waterfalls or fish ponds.
Surface Pump is recommended for larger ponds which over 4,000 gallons, or when higher flow is needed
How to calculate flow rate?
How to calculate flow rate?
Required GPM = Total Pond Volume (gallons) ÷ Desired Turnover Time (minutes)
The desired turnover time could be determined by the following guidelines.
Without fish: circulate once every 4–6 hours
With fish: circulate once every 1–2 hours
Koi pond: circulate every hour
For example,
Pond volume = 1,350 gallons
Full circulation every 2 hours = 120 minutes
Required GPM = 1,350 ÷ 120 = 11.25 GPM
In this case, a pump rate 12-13 is recommened.
How to calculate head
How to calculate head
Lift head = H1 + H2 + 10%L
For example:
If you're pumping from a pond to an overhead tank with a sprinkler system:
Total vertical lift (H1+H2) = 25 ft
Horizontal distance = 95ft
Lift head = 25+0.1*95 = 34.5 ft
Ideal lift head = 34.5*1.3 = 45 ft
In this case, pump rated > 45ft is recommended.
