Fish need dissolved oxygen, and it drops fastest in warm, still weather and at night. Floating aerators keep oxygen up in fish ponds, fishing lakes and reservoirs, and hire units can be brought in quickly when levels crash and fish are at risk.

## When does a fish pond or lake need aeration?

- Warm, still weather, when water holds less oxygen
- Algal blooms, which use oxygen at night
- Heavy stocking
- After a storm or a turnover in a deep lake

## Which aerators suit fish waters?

Compact floating surface aerators suit ponds from about 0.5 to 0.8 m deep. Larger lakes and reservoirs use bigger floating aerators or aerator mixers, and hire units cover emergencies.

## Frequently asked questions

### Can I hire an aerator to save fish?

Yes. Hire units are used when oxygen levels crash in lakes and reservoirs. Send an enquiry with the water area, depth and how soon you need cover.
