🌊 Key Features
✅ Dual sponge design – Offers larger filtration surface area, traps debris effectively, and provides a strong home for beneficial bacteria.
✅ Air-driven system – Connects to an air pump (not included), producing bubbles that circulate water and increase oxygenation.
✅ Safe for shrimp & fry – Gentle water flow and soft sponge foam prevent tiny creatures from being harmed.
✅ Mechanical + Biological filtration – Sponge removes particles while bacteria colonies grow to maintain water quality.
✅ Durable & reusable – Sponges can be rinsed multiple times and last for months before replacement.
✅ Low-cost & silent – Runs with an air pump, requiring no electricity for the filter itself.
