A pressure gauge should be installed on every windmill aerator to determine how well it is producing air and if the air is reaching the diffuser under the ice. Higher pressure than 1/2 the depth indicates the airline is likely plugged which can commonly occur during ice conditions. There should be a freeze control or air pressure tank between the windmill and the water. This tank collects water condensate and provides a place to put the air gauge and an adjustable pressure relief valve to protect the air production mechanics during airline blockages.
