Filters for Tanks up to 100L

Aquarium Filters for Tanks up to 100 Litres

Small and nano aquariums up to 100 litres (roughly nano to 2-foot tanks) need gentle, right-sized filtration, too much flow stresses fish, too little leaves water dirty. This collection brings together internal, hang-on-back and sponge filters matched to smaller tanks, ideal for betta, shrimp, nano community and 1–2 ft setups. Shop trusted brands like Sobo, Aquael, OASE and Blue Pet, shipped across India.

As a guide, aim for a filter rated around 4–6× your tank volume per hour: for a 60L tank that's roughly 250–400 L/H. For shrimp and fry, a sponge filter or an internal filter with a pre-filter sponge is safest.

Frequently asked questions

What filter is best for a small or nano aquarium? An adjustable internal filter or an air-driven sponge filter is ideal, both give gentle, fry- and shrimp-safe flow with strong biological filtration.

What size filter for a 2 foot tank? A 2 ft tank is usually 40–60L; a filter rated around 300–500 L/H (or one specced up to 100L) is a good match.

Are these filters good for betta fish? Yes, choose a model with adjustable or gentle flow, since bettas dislike strong currents. Sponge and slim HOB filters are popular betta choices.
