Dedicated koi pond

A dedicated pond puts fish observation and maintenance first. Plan access to the pond floor, drains and filtration before deciding how the edges will look.

Design point	What to plan	Why it matters
Depth	Assess local heat, freezing and winter management.	Set the depth for your site and fish.
Floor	Plan a route to collect and remove settled solids.	Keep cleaning and inspection access.
Volume	Measure the working volume and allow for adult fish.	Match filtration and aeration to the expected load.
Circulation	Plan for floating debris and settled solids.	Choose collection points and filter access together.

Garden pond with koi

Plant shelves, stones and waterfalls can be part of the design. Leave space to observe the fish and reach the spots where leaves and sediment collect.

Raised koi pond

Raising the rim can improve viewing and reduce excavation. Have the base and walls assessed for the water load and plan safe access, overflow and winter protection for your site.

Naturalistic pond

A planted layout can provide shade and a softer edge. Allow for plant maintenance, circulation and predator protection. Judge the filtration and aeration needs from the fish load and water conditions.

Separate quarantine tank

Give new fish a separate observation system with its own water, filtration, aeration and equipment. Keep nets and buckets separate from those used for resident fish. Seek advice from an aquatic veterinarian when illness is suspected.
