Promotes oxygen gas exchange. Creates a large surface area for the 'beneficial' bacteria to colonise, increasing the break down of harmful Nitrates and Nitrites producing better quality water for your fish.Paddle wheel design breaks water flow helping de-gas and aerate water.Water paddles maximize dissolved oxygen levels.Textured surface maximizes space for beneficial bacteria populations and water retention. Compact size allows for placement into smaller areas.
