Update on solar aerator...Very cold temps last couple of weeks (below zero most of the days). Aerator continues to pump through out the day but not enough water movement to keep ahead of the frigged temps. Approximately 4-6" of ice formed over the diffuser area over the last couple of weeks. With warmer temps, drilled holes, 4 hrs to create the pictured opening. Running the pump at approximately half speed all winter. Thin ice sign is being ironic as it looks like it fell through
