Kasco Marine

Much of what pond owners call us about starts with still water: surface odors, muck buildup, murky water, and fish struggling in hot weather or under winter ice. Moving, oxygenated water supports fish and beneficial bacteria and helps limit stagnant areas.

The equipment also handles property-side jobs. A circulator helps keep floating weeds and debris off a dock, and a de-icer helps keep open water around boats, pilings, and bulkheads through winter.

Nutrient loads, feeding, and organic matter still shape a pond, so treat this as one part of a routine rather than a cure.

Decorative fountains (J Series)

Choose a J Series fountain when the display is the priority. It takes interchangeable spray nozzles, so you can change the look without changing the fountain. The Mahogany, Mighty Oak, Madrone, Magnolia, Palm, and Fern patterns run from a two-tier ten-stream design to a fanned thirteen-stream display.

Mahogany and Mighty Oak fit J Series units from 3/4 HP to 7.5 HP, and Palm fits 2 HP to 7.5 HP.

Aerating fountains (VFX)

Choose the VFX when you want a visible display and more water movement at the same time. Its wide V-shaped pattern agitates water across the surface, which adds oxygen while still giving you something to look at.

If the display matters more than the aeration, compare our Kasco fountains. If oxygen is the only goal, see our Kasco aerators.

Surface aerators

Choose a surface aerator when oxygen is the goal and you do not need a spray display. These fit aquaculture, wastewater lagoons, shallow ponds, and sites where water clarity and oxygen matter more than spray height.

Bottom-diffused aeration systems

Choose a bottom-diffused system when the pond is deep, or when you would rather not run an electrical cord through the water. A shore-mounted compressor pushes air through weighted tubing to diffusers on the pond floor, and rising bubbles pull deeper water toward the surface.

Kasco's Home Series is meant for ponds up to 2 acres.

Water circulators (AquatiClear)

Choose AquatiClear when the problem is floating weeds, debris, or muck at a dock, marina, or shoreline. It moves water in a set direction and its design resists clogging, so it can run continuously. For oxygen across a whole pond, compare our Kasco aerators instead.

De-icers

Choose a de-icer when winter ice is the concern, to help keep open water around docks, boats, pilings, and bulkheads where ice can cause damage.

Start with four things:

• What you want the unit to do: display, oxygen, directed water movement, or ice defense.
• Pond surface area and shape: long, divided, or irregular ponds may need more than one unit or diffuser to circulate the whole body of water.
• Average and maximum depth: shallow water favors floating fountains and surface aerators, while deeper ponds usually get more from bottom-diffused aeration. As a general rule, water deeper than about 8 feet is where diffused aeration starts to make sense.
• Power supply: what is available at the shore sets your options.

Kasco replacement motors are stocked from 1/2 HP up to 7.5 HP, so matching the model number on your existing unit is usually straightforward. Confirm the ratings shown on the individual product page before you order.
