Aclimation

Prepare the Tank:

Make sure the new tank is set up with proper filtration and has been cycled to establish beneficial bacteria.

Check that the water temperature, pH, and other water parameters match those of the water the guppies are coming from.

Float the Bag:

Place the sealed bag containing the guppies in the new tank. Let it float for about 15-20 minutes to equalize the temperature between the bag water and the tank water.

Add Tank Water to the Bag:

Open the bag and roll down the top edges to create an air pocket so it can float. Every 5 minutes, add a small amount of tank water to the bag (about 1/4 cup). Do this for about 30 minutes. This helps the guppies gradually get used to the water chemistry in the new tank.

Release the Fish:

After the acclimation period, gently net the guppies out of the bag and place them into the tank. Avoid pouring the bag water into the tank to minimize the risk of introducing any potential contaminants.

Sponge Filter – Quiet, Reliable Filtration (Up to 20 Gallon Aquariums)

This sponge filter is designed for aquariums up to 20 gallons, offering gentle and dependable filtration for small to medium tanks. The high-density sponge provides effective mechanical and biological filtration, helping remove debris while supporting beneficial bacteria for stable water quality.

Powered by an air pump (not included), the filter runs quietly and creates smooth water movement that won’t stress fish or disturb plants. With no motor and no strong suction, it’s safe for shrimp, fry, and sensitive fish, making it a great choice for community tanks, breeder setups, and quarantine aquariums.

In my opinion, this size is perfect if a nano filter feels too small but you don’t need a large, heavy-duty sponge yet—simple, efficient, and easy to maintain.

Key Features

  • High-density sponge for strong filtration

  • Suitable for aquariums up to 20 gallons

  • Gentle flow, safe for shrimp and fry

  • Mechanical + biological filtration

  • Quiet, air-powered operation (air pump required)
