Large Pond Kits

A matched kit takes the planning out of a pond build, so you are not left guessing whether the pump, filter and liner suit each other. It keeps circulation and filtration in step with the pond you are digging.

A matched setup is the practical answer to the problems that send pond owners looking for help:

• murky or discolored water
• leaves and surface debris sinking to the bottom
• odors and muck buildup
• low oxygen around fish and plants
• pumps that clog or filter too little water

Kit components are chosen to work as one system, so one part is not doing more than its share.

Most people are choosing between four kinds of product.

Lined water garden and koi pond kits

Choose a lined kit when you are building a contained pond from scratch and want a skimmer, a biological waterfall filter and a visible waterfall or stream.

EasyPro kits come in Mini, Small and Medium versions built around a liner and underlayment, a skimmer and an AquaFalls filter with a molded rock lip. The Small and Medium kits use a 45-mil EPDM DuraLiner, and the Medium kit pairs a PS1FB skimmer with a Medium AquaFalls filter. The Blue Thumb Elite kit matches liner, skimmer, biological waterfall filter, pump and fittings as one system. For smaller builds, see our pond kits.

Bottom-diffused aeration systems

Choose an aeration system when the pond is an unlined earth pond or a large, deep water body where oxygen and circulation matter more than a waterfall.

A compressor on shore pushes air to diffusers on the pond floor, and the rising bubbles move deeper water toward the surface. The Outdoor Water Solutions AerMaster Shallow models are sized for 0.5 to 1.5 acres. The AerMaster Pro Deep is the one to look at for ponds that reach 40 feet. EasyPro's high pressure rocking piston systems run a 2 hp SRC2002 compressor with either 6 or 10 diffusers.

Floating aerating fountains

Choose a fountain when appearance matters as much as circulation, or when the pond is shallow.

The Outdoor Water Solutions EcoSeries comes with four nozzles (Equinox, Jupiter, Neutron and Nova), and the Classic Series switches between three displays from one nozzle on ponds up to 5 acres. The Aerify moves 500 gallons per minute and runs in as little as 18 inches of water.

Bulk liner rolls

Choose a liner roll when your pond shape is custom and you would rather source pumps and filters separately. EasyPro DuraLiner is a 45-mil EPDM rubber liner sold in bulk rolls.

Start with the pond itself rather than the product.

• Footprint and depth. A lined pond needs liner sized for the length, width and depth you dig, including the overlap at the top. Deep open water asks for bottom-diffused aeration instead of waterfall filtration.
• Filtration and flow. Pump and skimmer need to move the pond's volume, and the biological filter needs enough media to handle your planned fish load.
• Your main goal. Fish and garden ponds are about clean containment and clear water. Acreage ponds are about oxygen and circulation across open water.
• Maintenance. A skimmer gives the pump a protected home and catches leaves before they sink and become muck.

If you are between two options, ask us before ordering. Kits with a little headroom for the pond are usually easier to live with than ones running at their limit.
