The difference is in the quality of the foam sponge. Hikari Aquarium Solutions Bacto-Surge Foam Filter employs the highest-quality foam sponge they could source to provide outstanding mechanical and biological filtration. Extreme foam density allows for greater surface area per square inch to support significant levels of beneficial bacteria. In addition, the unique air dispersion design maximizes uplift to pull aquarium water through the foam at a higher rate resulting in optimal conditions for beneficial bacteria AND thorough aquarium filtration.

Hikari Aquarium Solutions Bacto-Surge Foam Filter features locking internal connectors to prevent separation during operation and a heavy base to reduce chances of the sponge filter from floating.

Ideal mechanical and biological filter for:

• Nano tanks
• Smaller freshwater aquariums
• Breeding tanks
• Fry holding tanks
• Quarantine tanks
• Use with slow moving fish like Discus
• Polishing of marine aquariums

Sponge Filters & Breeding Aquariums
Breeding and raising fish is one of the most exciting and educational facets of the aquarium hobby. To ensure the safety and health of the fry, you must employ filtration gentle enough not to harm them, yet strong enough to maintain healthy water conditions.

Sponge filters have proven to be an excellent solution for filtering breeding aquariums, as they:

• Include no moving parts to harm the fry
• Provide an efficient form of biological filtration
• Allow water flow to be adjusted to meet the needs of the fry
• Are easily cleaned in aquarium water, preserving beneficial bacteria

In addition to a sponge filter in your breeding aquarium (which should be around 5 gallons in size), you will also need an air pump, a check valve, an air control valve, and a heater. The check valve will prevent flooding if power is lost, and the control valve will allow you to adjust the air output to the perfect level for the fry.

With the right equipment, you and your family can experience the excitement and rewards of breeding fish.
