Koi Pros

Koi pond builders and water feature care from Oceanside to Chula Vista

We serve San Diego County for construction, renovation and commercial maintenance, with routed residential service through North County and the coastal communities. Mild coastal weather is ideal for koi; inland valleys need the same heat planning as the Inland Empire.

    What shapes pond and water feature work in San Diego County

    Fill water

    Imported Colorado River and State Project water blended with local reservoirs and, in Carlsbad, desalinated seawater; hard and chloraminated nearly everywhere, with well water on rural lots in Escondido, Poway and Rancho Santa Fe.

    Heat, wind and evaporation

    Mild and nearly frost-free on the coast, hot in the inland valleys. Coastal lagoons keep humidity up and evaporation down; inland ponds need the same heat planning as the Inland Empire.

    Predators and wildlife

    Three coastal lagoons plus Mission Bay and Lake Hodges keep herons, egrets and night herons over the whole county; coyotes and bobcats are on nearly every rural and canyon-edge property.
