An aquascape (liner) pond uses a durable rubber liner as waterproofing, combined with dry-stacked boulders and gravel at the bottom. It is the most budget-friendly option and delivers a natural, organic feel. A concrete koi pond is built with shotcrete for maximum structural durability and longevity β€” it requires less routine maintenance and offers virtually unlimited design possibilities, from sleek modern shapes to elaborate natural forms.

The timeline depends on the size and complexity of your project. A Mini or Small Dream Pond can typically be completed within a few days, while larger or more intricate builds may take several weeks. During your initial phone consultation, our team will provide a detailed project timeline tailored to your specific vision and site conditions.

Permit requirements vary by city and county across Southern California. Many jurisdictions do not require permits for ponds under a certain depth or volume. For larger builds or in certain cities, permits may be necessary. The Koi Pond, Inc. can prepare permit-ready CAD drawings and manage the entire permit process on your behalf, ensuring full compliance with local regulations.

For a healthy koi environment, ponds should generally be at least 3 feet deep. Our Mini and Small packages start at 1.5–2 feet, which works well for ornamental purposes. Our larger packages reach 2–5 feet, providing better temperature stability and protection for koi β€” especially important in the warm Southern California climate. Our design team will recommend the optimal depth based on your koi goals and yard conditions.

A balanced combination of both is ideal. Some direct sunlight encourages healthy aquatic plant growth, but excessive sun can trigger algae blooms and dangerously overheat the water. We recommend positioning your pond to receive morning sun and afternoon shade. During your site assessment, our team will evaluate your specific yard conditions and recommend the optimal placement for both the health of your koi and the beauty of your landscape.

Water Quality Testing

Every visit

We test and balance pH, ammonia, nitrite, nitrate, and dissolved oxygen levels on every visit. Proper chemistry is the foundation of a healthy koi pond.

Filter Cleaning & Service

Monthly

Biological and mechanical filters are cleaned, backwashed, and inspected. A clean filter is the single most important factor in maintaining crystal-clear water.

Koi Health Inspection

Every visit

Our technicians visually inspect every fish for signs of disease, parasites, or injury. Early detection saves lives and prevents the spread of illness through your pond.

Algae & Debris Removal

Weekly / Bi-weekly

String algae, blanketweed, and surface debris are manually removed. We also net out leaves and organic matter before they decompose and spike ammonia levels.

Pump & Equipment Check

Monthly

We inspect pumps, UV sterilizers, aerators, and all plumbing for leaks, wear, or reduced flow. Catching equipment issues early prevents costly emergency repairs.

Annual Deep Clean

Annually

Once a year we perform a full pond drain, pressure wash of walls and bottom, gravel vacuum, and complete system reset β€” giving your pond a fresh start every season.

How to Keep Your Koi Pond Water Crystal Clear

Proper filtration is the single most important factor in koi pond health. A biological filter with adequate surface area for beneficial bacteria, combined with a mechanical pre-filter to remove solids, will keep your water clear and your fish healthy year-round. Test ammonia, nitrite, nitrate, and pH weekly β€” especially in the first 6 months after a new build.

Southern California Koi Pond Care Through the Seasons

Unlike colder climates, Southern California ponds stay active year-round β€” which means your koi never stop eating and your filter never gets a break. In summer, watch for oxygen depletion during heat waves (add a waterfall or air stone). In winter, reduce feeding as metabolism slows. Spring is the best time for water changes and filter cleaning before the warm season begins.

The Best Plants for a Southern California Koi Pond

Native and drought-tolerant plants are ideal for SoCal pond edges β€” they look beautiful, require minimal water beyond what splashes from the pond, and provide natural filtration. Our favorites: Iris, Horsetail Reed, Dwarf Papyrus, and Water Lily. Avoid invasive species like Water Hyacinth, which can overtake a pond quickly in our warm climate. Always leave 30% of the water surface open.
