hygger Single Sponge Aquarium Filter, super mini, for 0.5-5 gallon fish tanks

An air pump drives the flow through this sponge aquarium filter, so the two are used together. hygger rates the unit for fish tanks or fish bowls between 0.5 and 5 gallons, and the super mini size leaves plenty of room in a small tank. Inside the pack you will find the filter itself, a spare fine sponge and a suction cup.

What arrives in the pack

• 1 single mini sponge filter
• 1 spare fine sponge
• 1 suction cup

Does this filter suit your aquarium setup?

An air pump and airline hose of 4 mm diameter are needed before the unit can run at all. Without them it has no way to move water. The rated tank range is 0.5 to 5 gallons, and the suction cup fixes the filter to the back wall of the aquarium.

How the unit is put together and what it does

• One sponge does the whole filtration job, and a second fine sponge comes in the box as a spare.
• A strong suction cup holds the unit against the back wall of the aquarium.
• Every part comes apart, and the pieces go back together again.
• The outlet tube for air and water is telescopic, so it can be set above or below the water line.
• Water in the tank moves in small, slow currents while the filter runs.
• With the outlet sitting under water, more air is added to the tank.

hygger advises against stocking a new tank with a lot of fish straight away. Where a tank is already running, keep the old filter going alongside the new one for a while so bacteria can build up in it.

Cleaning the sponge and filter

About once a month the sponge needs a clean. Use aquarium water rather than tap water, and rinse or squeeze the sponges in it. Squeeze and rinse at least 5 to 10 times, until the water running out is no longer dirty, then carry on the cleaning for 2 to 3 more days until the aquarium water is clear.
