The smaller models have two speed settings and the larger SR 12000 model has a variable speed control. As a guide, the 9500 model or 12000 is suitable for an aquaponics system with 500L of water and 40 small fish (5 - 10 full grown fish).

Aqua One Air Pumps are Suitable for:

  • Aquariums
  • Aquaponics
  • Hydroponics
  • Deep water culture

Aqua One Air Pump Features:

  • Smaller models have dual speed control - high or low
  • The SR 12000 model features a variable speed control knob

Please note, diaphragms are a consumable part of all of the air pumps, and are not covered under warranty. The harder that the air pumps work, the more likely the diaphragms will fail! Please check for replacement diaphragms on the website.
