1. Airlines can be run into the pond with air stones attached to the end, which will aid in the circulation of water in “dead spots”. These are areas in the pond where water does not flow. As a result these areas become breeding grounds for algae and allow toxic gases like ammonia to accumulate. Extra circulation not only helps your fish to maintain their health but also aids in keeping the pond water clean by circulating anything which may have settled on the base to be picked up by the filtration system. Running airlines into the pond can also aid in providing oxygen in the event that the main filtration system fails.

2. Airstones should also be placed in the filtration system to boost the amount of oxygen in the water. This injection of oxygen will allow the nitrifying bacteria (which needs oxygen to survive to detoxify ammonia and nitrite) to perform more effectively in the break down of toxins and replenish oxygen used by this bacteria.
