Volcano III Floating Pond Aerator

Why choose Volcano III?

• Serious oxygenation where you need it
  Rapid water turnover at the surface improves DO levels in the critical upper column.
• Algae and odour control
  Continuous circulation disrupts stagnant zones to help limit algal blooms and surface scum.
• Built to graft
  Marine-grade components and a robust float assembly deliver reliable, round-the-clock performance.
• Simple to install, easy to maintain
  Drop-in floating design with minimal anchoring. Straightforward access for servicing.
• Low visual impact
  Produces a vigorous rolling boil rather than a decorative fountain display—ideal for working fisheries.

Best for

• Garden and ornamental ponds that need reliable daily aeration
• Heavily stocked ponds where fish activity increases oxygen demand
• Ponds prone to stagnation, surface scum, or unpleasant odours during warm weather
• Sites where discreet, non-decorative surface movement is preferred over fountain-style displays

How it works

A high-torque motor drives an impeller that draws low-oxygen water up and throws it across the surface in a turbulent boil. This agitation maximises air-to-water contact and mixes the upper layers, improving oxygen transfer and circulation across a wide area.

Key features

• Floating surface aerator with heavy-duty impeller
• Stable float with stainless fixings and strain-relieved cabling
• Choice of cable lengths and mooring options
• Weather-resistant motor housing for continuous outdoor use
• Compatible with optional night-use lighting and control gear (timers/DO controllers)

Selecting the right aerator

• Volcano III – Maximum surface agitation and turnover with a low visual profile.
• Diffused aeration – Best for full-depth oxygenation in deeper lakes (often paired with Volcano units near pegs or hot-spots).
• Aerating fountains – Add visual display when presentation matters, with measurable aeration benefits.

FAQs

Q: Will a surface aerator oxygenate my whole lake?
A: It significantly improves DO around the unit and across the upper layers. For deep lakes, pair with diffused aeration for full-column coverage.

Q: Is it noisy?
A: You’ll hear a low working hum and water movement close by; sound drops off quickly with distance.

Q: How many units do I need?
A: Depends on area, depth, fish biomass and water quality goals. We’ll specify a layout after a quick assessment.

Q: Can I run it at night only?
A: Yes—timers or DO controllers can automate operation around your fish and site needs.
