How to Oxygenate a pond quickly "fix it"

Temperature- Warm water loses its capacity to hold onto oxygen particularly at temperatures above 29 degrees Celsius. Warm water combined with poor water circulation can create pockets of oxygen-depleted water harmful to pond inhabitants.


For a shallow pond in full sun drape or fix shade cloth over the pond & add an extra pump for more water movement.

Biological load- Simply put, more pond inhabitants mean greater demand for oxygen. Poor quality food will cause more phosphates & organic material within the pond to complete the process of breaking down organic waste good bacteria needs oxygen, heavily stocked ponds can deplete the existing oxygen supply.


 Feed Medium protein, low phosphate  Australian quality Pellets

Water Clarity- dark, murky or turbid water can limit the ability of plants to photosynthesize & generate oxygen.


Maintain clear water for healthy plant growth essential for natural oxygen production. Use clear water product.


Surface exchange - Encourage proper gas exchange by keeping an area of open water. This open area should be free of vegetation so surface water is exposed to fresh air.

Mixing - Water turbulence of any kind, regardless of how it's generated, significantly increases gas exchange. The fastest, easiest way to raise the oxygen level in your pond is a water change or with an aerator, fountain, or waterfall.
