Installation & Compatibility Notes

• Confirm your pond volume and the number of air outlets/diffusers you need before ordering — air output should be matched to pond size and stocking density, not just budget

• Use with weighted air line and air stones/diffusers rated for the pump's output
• Use a suitably rated outdoor power point with RCD/earth leakage protection
