Koi ponds are all the rage for homeowners these days. There is nothing like relaxing at the water’s edge while feeding a writhing school of koi or goldfish as they fight for every last scrap of Purina fish chow. It kind of makes you feel like a benevolent despot with your own little fiefdom of fishy peasants. But let’s be honest, this is the kind of landscaping project that often winds up with a pond full of dead fish. How can you keep your swimming serfs in good health?
Koi and goldfish ponds need periodic maintenance so the water’s chemical balance stays within the range that allows fish to thrive. A heater may be necessary to keep the pond at proper temperatures. Plants that help clean the water are always a welcome addition since they supplement the filtration system. Waterfalls or fountains help keep oxygen levels high. Clear water is important – it lets you actually see the fish you spent so much money on.
