Ammonia Removers and Ozone
Tech Talk 113
When using many ammonia removers (AmQuel®, ClorAm-X®, etc.) it is recommended that ozonation be discontinued for a period of 48 hours from the time of treatment. These products contain reducing agents that cause the oxidation/reduction potential (ORP) to drop significantly. If ozonation is not turned off, then the decline in ORP can cause ORP controllers to "falsely" sense a problem and turn on the ozone equipment with a resulting overdose of ozone. Aeration, however, should be continued at all times.
