Goldfish pop eye typically caused by low oxygen levels in water

Goldfish pop eye is not uncommon in the industry. Most goldfish keepers are unaware of their fish’s needs when it comes to water quality. The most common parameter is pH; potential of hydrogen, however, there’s more to pH than meets the eye. All too often goldfish keepers look only at pH to determine the health of water

Thought to be foundation of alkalinity, pH is misunderstood by even the best goldfish keepers. The term, potential of hydrogen is the key. Potential, indicating the water’s capability. This critical parameter is made up of oxygen and carbonate mineral combined. It’s possible to have a high pH that is dependent solely on carbonate mineral; KH, however, this doesn’t mean the water will support life

Carbonate mineral should be measured first and foremost to determine if pH is healthy. The comfort zone for KH is 120 to 160 ppm. When KH is in this range, but pH is low, this indicates oxygen levels are low

Most goldfish keepers understand that fish water must be oxygenated, but this too is misunderstood. Learn all about oxygenating water
