Water Recreation is San Diego County's trusted choice for pond maintenance, pond cleaning, koi pond service, and full water feature management. For over 45 years we've maintained backyard ponds, koi ponds, HOA lakes, estate water features, and commercial fountains from La Jolla and Del Mar to Escondido, Temecula, and the inland valleys. Our technicians combine water chemistry expertise, aquatic biology certifications, and hands-on experience with San Diego's Mediterranean climate — so your pond stays clear, balanced, and healthy year-round.
San Diego's coastal marine layer, summer heat spikes, and year-round mandatory water conservation rules create pond challenges you won't find in most of the country. Green water from algae blooms, low oxygen on hot days, evaporation loss, and nutrient-heavy runoff during storm events are the most common issues we solve. Whether you own a decorative pond, a koi pond with prized fish, an HOA lake, or a commercial water feature, we design a maintenance plan matched to your pond, your property, and San Diego's climate.
If your pond is green, cloudy, overgrown, losing water, or your fish are stressed, we can diagnose and restore it — and prevent the problem from coming back.
Ready to improve the health, clarity, and beauty of your pond? Our technicians are available Monday through Thursday for residential service and Saturdays for commercial and HOA properties.
Our pond maintenance programs are designed to support healthy water conditions while enhancing the beauty and functionality of your property.
We test pH, ammonia, nitrite, nitrate, dissolved oxygen, alkalinity, algae activity, and clarity. For koi ponds, fish ponds, and HOA lakes we also screen for parasites and pathogens on request. Based on your pond's specific results we apply targeted, fish-safe treatments — not one-size-fits-all doses — to restore balance and prevent recurring problems.
Proper aeration is essential in San Diego's warm, dry climate — especially for koi ponds, where oxygen levels drop fast on hot summer days. We design, install, and service surface aerators, sub-surface diffused aeration systems, and solar-powered aerators for ponds and lakes across San Diego County. Good aeration prevents fish stress, controls algae, reduces stagnation, and keeps your water clear.
We provide safe, effective treatments for nuisance algae, duckweed, cattails, and invasive aquatic weeds. Our methods reduce overgrowth without harming fish or beneficial plant life.
Our filtration solutions help remove debris, excess nutrients, and suspended particles—dramatically improving water clarity and reducing long-term maintenance needs.
We repair, install, and maintain fountains and water features that improve circulation and enhance pond aesthetics. Our services include pump repair, head replacement, and flow adjustment.
Our San Diego koi pond service includes health inspections, water chemistry tuning for koi and goldfish, quarantine recommendations for new fish, and fish stocking for decorative, recreational, and natural ponds. We work with koi owners, estate properties, and residential clients across San Diego County — and can coordinate with your koi veterinarian when needed.
Cracks around pond edges, walkways, and concrete features can worsen water loss and structural deterioration. Our steam crack repair services seal damage, prevent leaks, and restore surface integrity.
We clear excess debris, organic buildup, and sediment layers that can lead to odors, poor water clarity, and nutrient overload.
We provide professional fountain restoration services, including fountain head replacement, pump repair, and filtration system restoration. Our technicians have extensive experience bringing residential and commercial fountains back to full performance, clarity, and visual appeal.
San Diego County’s diverse geography—from coastal communities to inland valleys—creates unique water management challenges. Without consistent care, ponds may develop:
Consistent maintenance not only improves pond appearance but also prevents costly structural or ecological problems.
We tailor our programs to the specific climate, runoff patterns, and water-use rules found throughout San Diego County communities — from coastal La Jolla and Del Mar to inland Escondido, Poway, and Temecula.
We tailor our programs to the climate, runoff patterns, and ecosystem needs of each area, ensuring your lake stays stable throughout the year.

Pricing depends on pond size, fish load, and whether you need a one-time cleaning or ongoing maintenance. Most residential pond maintenance plans in San Diego County start at a flat monthly rate that covers regular water testing, filter service, aeration checks, and algae control. Call (949) 718-7478 for a free estimate based on your specific pond.
Most San Diego ponds benefit from monthly maintenance. Koi ponds, heavily stocked fish ponds, and HOA lakes often need biweekly service during summer when heat and algae activity peak. Decorative ponds with no fish may only need quarterly visits.
Yes — koi pond service is one of our most-requested specialties in San Diego County. We handle routine maintenance, water testing, filter tuning, UV clarification, aeration, algae control, fish health checks, and koi-safe treatments. We serve koi owners from La Jolla and Del Mar to Escondido, Rancho Bernardo, Poway, and Temecula.
Green water is caused by free-floating algae blooms, which thrive in San Diego’s warm, sunny climate — especially in ponds with excess nutrients, direct sun exposure, or weak circulation. We fix it with UV clarification, biological balancing, shade strategies, and filtration upgrades. Most ponds clear within 1–3 weeks of the right treatment plan.
Absolutely. Cloudiness is usually caused by suspended sediment, bacterial bloom, or filter overload. We test the water, identify the root cause, and combine mechanical filtration, beneficial bacteria, and targeted treatments to restore clarity — often within a single service visit.
San Diego has year-round permanent water-use restrictions. Ornamental fountains must recirculate water, and during drought response levels the city may limit refilling of decorative ponds. A well-maintained pond with a sealed liner, good aeration, and evaporation controls minimizes refills and keeps you compliant. We can audit your pond for water-efficiency and recommend upgrades.
Yes. We maintain HOA lakes, community ponds, apartment and condo water features, commercial fountains, and golf-course ponds across San Diego County. We provide scheduled maintenance, emergency service, detailed reporting for boards and property managers, and insurance documentation. Commercial and HOA service appointments are available Saturdays.
Yes. Water Recreation handles pond installation, fountain installation, and water feature design for residential, estate, and commercial properties in San Diego County. We also take on pond renovations, liner replacements, waterfall and stream builds, and fountain restorations for existing features that need a refresh.
Yes. Leak detection is one of our core services. We locate leaks in liners, around waterfalls, at plumbing joints, and through concrete cracks — then repair with the right method for the material (liner patching, hydraulic cement, polyurethane injection, or full reline). If your pond is losing more than an inch a week beyond normal evaporation, call us.
For fish emergencies (distressed fish, sudden die-off, pump failure in summer heat, major algae bloom) we prioritize same-week service across San Diego County. For routine maintenance we typically schedule within 1–2 weeks. Call (949) 718-7478 to check current availability.
