1,000+ gallons<\/strong> (larger is better)<\/p>\n<\/li>\n- \n
At least 3 feet deep<\/strong> to protect from predators and temperature swings<\/p>\n<\/li>\n<\/ul>\n<\/span>📏 Space Rule of Thumb<\/span><\/h3>\n\n- \n
Allow 250 gallons per adult koi<\/strong><\/p>\n<\/li>\n- \n
Don\u2019t overstock \u2014 fewer fish = healthier pond<\/p>\n<\/li>\n<\/ul>\n
<\/span>🌀 Filtration and Aeration<\/span><\/h3>\n\n- \n
Strong biofilter<\/strong> to handle waste (koi produce a lot!)<\/p>\n<\/li>\n- \n
UV clarifier<\/strong> to prevent green water (algae)<\/p>\n<\/li>\n- \n
Aerator or waterfall<\/strong> for oxygen, especially in warm weather<\/p>\n<\/li>\n<\/ul>\n<\/span>🌡️ Water Quality & Parameters<\/span><\/h2>\n\n

Supplement with treats: peas, lettuce, watermelon, oranges, shrimp<\/p>\n<\/li>\n<\/ul>\n Note<\/strong>: In temps below 50\u00b0F (10\u00b0C)<\/strong>, koi metabolism slows \u2014 stop feeding in winter unless using cold-water food.<\/p>\n<\/span>🧊 Winter Care (for Cold Climates)<\/span><\/h2>\n\n- \n
Koi can survive under ice if the pond is deep enough<\/p>\n<\/li>\n - \n
Use a pond heater or de-icer<\/strong> to keep a breathing hole open<\/p>\n<\/li>\n- \n
Don\u2019t disturb hibernating fish too much \u2014 they\u2019re delicate in cold temps<\/p>\n<\/li>\n<\/ul>\n <\/span>🛡️ Common Problems<\/span><\/h2>\n\n- \n
Algae blooms<\/strong> \u2013 often caused by too much sun or overfeeding<\/p>\n<\/li>\n- \n
Ammonia spikes<\/strong> \u2013 usually from overstocking or poor filtration<\/p>\n<\/li>\n- \n
Parasites or ulcers<\/strong> \u2013 check for flashing, spots, or sluggish behavior<\/p>\n<\/li>\n- \n
Predators<\/strong> \u2013 raccoons, herons, and cats love koi! Use pond netting or decoys.<\/p>\n<\/li>\n<\/ul>\n<\/span>❤️ Fun Facts<\/span><\/h2>\n\n- \n
