A koi pond doesn’t fail all at once. It slowly drifts out of balance. Water clarity drops. Filters clog. Fish become stressed. Then one day you’re dealing with algae blooms, equipment failure, or fish loss that could have been prevented. Koi Pros provides professional pond maintenance for residential and commercial properties across California. Our licensed technicians manage water quality, filtration performance, seasonal changes, and preventative repairs so ponds stay clear, stable, and healthy year-round, not just after problems appear. This service is designed for pond owners who want long-term reliability and expert care, not one-time cleanups or DIY maintenance. With over 40 years of hands-on experience maintaining koi ponds throughout California, we don’t treat maintenance as occasional cleaning. We manage ponds as complete systems, because that’s the only way they stay reliable long term.
When a pond gets out of control, it’s rarely just dirty water. Sludge builds up, algae takes over, filtration performance drops, and fish health begins to suffer. At that stage, surface skimming or partial cleanouts won’t solve the problem. The pond needs a proper reset. Koi Pros provides professional pond cleaning services across California for ponds that require more than a quick rinse. Our team removes built-up debris and sludge, cleans and restores filtration components, rebalances water quality, and stabilizes the system so the pond functions correctly again, not just temporarily looks better. This service is intended for ponds that have fallen behind or are showing signs of imbalance. Many pond owners choose to transition into ongoing maintenance after cleaning to prevent the same problems from returning. We clean ponds with a restoration-first approach, addressing buildup, filtration performance, and water balance so results last well beyond the initial service.
Building a koi pond is not a cosmetic project. Structural shortcuts, poor circulation planning, and undersized filtration systems lead to leaks, unstable water quality, and costly corrections that often surface long after construction is finished. Koi Pros provides professional pond construction services across California for clients who want their pond engineered correctly from the start. We design and build complete pond systems, overseeing layout, excavation, structural integrity, filtration, circulation, and long-term performance considerations so the finished pond functions reliably as a living system, not just a visual feature. This service is intended for homeowners and commercial properties planning a permanent koi pond or water feature and who want clear guidance, accountable project oversight, and results that hold up under real-world use. Our construction process is built around long-term stability and system balance, ensuring your pond continues to perform consistently years after installation without recurring issues or corrective work.
Fountains fail for one reason more than any other: poor mechanical setup. Pumps run dry, plumbing leaks, flow rates fall out of balance, and small issues turn into repeated shutdowns and costly repairs. When a fountain isn’t engineered and maintained correctly, it becomes a liability instead of a feature. Koi Pros provides professional fountain services across California for residential and commercial properties that need reliable performance, not constant fixes. We handle fountain installation, cleaning, repairs, and system tuning with a focus on proper pump sizing, flow balance, plumbing integrity, and long-term operational stability. This service is designed for property owners who want fountains that run quietly, consistently, and predictably, without ongoing troubleshooting or patchwork repairs. Our approach prioritizes mechanical precision and system reliability so your fountain operates as intended day after day, not just immediately after service.
When a fountain stops working properly, the problem is rarely isolated. A failed pump stresses plumbing. Flow imbalance accelerates wear. Electrical issues trigger shutdowns. Without correcting the underlying failure chain, repairs don’t last and breakdowns repeat. Koi Pros provides professional fountain repair services across California for residential and commercial properties dealing with persistent leaks, noise issues, performance loss, or non-functioning fountains. We evaluate how the entire system is operating, identify what’s causing failure, and correct it at the source so the fountain returns to stable, predictable operation. This service is for property owners who are finished with temporary fixes and want the problem resolved in a way that holds up under continuous use. Our repair work restores mechanical balance and operational stability so the fountain runs reliably after service without recurring issues or constant oversight.
Fountain construction failures don’t announce themselves on day one. They show up later as uneven flow, excessive noise, recurring shutdowns, and premature equipment wear caused by poor hydraulic planning and incorrect system integration. By the time these problems surface, they’re expensive to undo. Koi Pros provides professional fountain construction services across California for residential and commercial properties that require predictable performance, not trial-and-error installation. We design and build complete fountain systems with proper hydraulic balance, structural integration, coordinated equipment selection, and long-term operational stability so the finished fountain performs as intended mechanically, not just visually. This service is for clients who want a permanent water feature built with disciplined planning, clear execution, and full accountability, not cosmetic construction that leads to future repairs or redesigns. Our construction approach prioritizes flow control, mechanical reliability, and serviceability so the fountain continues to operate smoothly and consistently long after installation is complete.
Lakes don’t fail suddenly. They decline through gradual water quality imbalance, sediment buildup, unmanaged vegetation, and circulation issues that compound over time. When maintenance is reactive instead of planned, small issues turn into ecological problems, costly interventions, and stakeholder concerns. Koi Pros provides professional lake maintenance services across California for residential communities, commercial properties, and managed sites that require consistent water quality, ecological balance, and dependable long-term oversight. We manage lake systems with a focus on water monitoring, vegetation control, circulation support, and preventative maintenance so conditions remain stable and predictable throughout the year. This service is intended for property owners and managers who need reliable lake performance without emergency-driven decisions or fluctuating maintenance standards. Our maintenance approach emphasizes proactive management and system stability to keep lakes functional, presentable, and environmentally responsible over the long term.
Lake cleaning becomes necessary when sediment accumulation, organic debris, excess nutrients, or unmanaged growth begin to interfere with water quality, appearance, or functional use. When these conditions persist, they accelerate long-term decline and make future management more complex and costly. Koi Pros provides professional lake cleaning services across California for residential communities, commercial properties, and managed sites that require a controlled, corrective reset, not surface-level cleanup. We remove accumulated debris and sediment, address problem areas contributing to imbalance, and restore baseline conditions so the lake can return to stable, manageable operation. This service is intended for lakes that have fallen behind on upkeep or are showing measurable signs of deterioration and require structured intervention rather than temporary cosmetic improvement. Our lake cleaning process focuses on restoring functional conditions and preparing the lake for effective ongoing maintenance, not short-term visual fixes.
Waterfalls rarely fail from age alone. They fail when flow design, base preparation, or stone support are incorrect from the start. These issues show up as leaks, shifting rock, uneven sound, and recurring repairs that worsen over time because the underlying structure was never right. Koi Pros provides professional waterfall construction and repair services across California for residential and commercial properties that need waterfalls built or corrected to function properly as part of a complete water system. We design, construct, and repair waterfalls with precise attention to flow rate, elevation change, stone stability, and long-term structural integrity so the feature performs consistently instead of degrading season after season. This service is for clients who want a waterfall that flows evenly, sounds natural, and holds its structure over time, not decorative installs or patch repairs that require constant adjustment. Our approach focuses on correcting underlying flow and structural issues so new waterfalls perform correctly from day one and existing waterfalls operate reliably after repair without repeat failures.

There are a number of fish that can help control algae and algal blooms, but some of the most popular include the goldfish, cichlids, and barbs. These fish have a natural instinct to hunt and eat algae, so they are perfect for keeping algae levels under control in water bodies. Additionally, these fish have a strong swimming ability which helps them to patrol large areas quickly.
Bass are a major component of many fisheries across the country, and as such, they are a keystone species. They play an important role in the food chain by feeding on smaller fish and cleaning up water pollution. However, bass can also negatively impact water quality by eating large amounts of aquatic vegetation, which can lead to algae blooms.
Keeping our lakes clean and healthy is important for a number of reasons. Not only does it protect the environment, but it also provides a habitat for many different types of aquatic life. Lakes and other bodies of water provide a home for fish, amphibians, reptiles, birds, and other animals. In fact, over 1,500 species of birds rely on lakes and other waterways for their survival.
There are a few things that you can do to improve the water quality in your lakes. First, make sure to keep debris and plant material away from the lakes. Second, try to use organic practices when disposing of waste. Third, make sure to use only approved pesticides and fertilizers when working with plants. Finally, improve the water’s clarity by using appropriate lake treatments.
Yes, there is a way to reduce or prevent toxic algal blooms in our lakes. One effective method is to reduce nutrient inputs, which can help to control algae growth. Additionally, water filtration and treatment can help to remove pollutants and heavy metals that can contribute to the growth of toxic algae. And finally, weather modification technologies can be used to artificially cool or warm water temperatures, which can help to regulate the growth of algae.
We have expanded our activities and now provide several other services to meet our clients’ wider needs.
