Aquael Ultra Aquarium Canister Filter | 100–450L (3–5 ft) | Fish Bazaar

The Aquael Ultra aquarium canister filter is an affordable, feature-rich external filter range for fish tanks from roughly 100 to 450 litres (3 to 5 feet), available in three models — Ultra 900, 1200 and 1400 — delivering 900 to 1,400 litres per hour of multi-stage filtration. Made by Aquael, the well-regarded Polish brand known for innovative, value-for-money equipment, the Ultra series hides in your cabinet, holds plenty of filter media and keeps planted and community tanks crystal clear — one of the best-value canister filters available in India.

What is the Aquael Ultra Canister Filter?

Short answer: A sealed external (canister) aquarium filter range for tanks of 100–450 litres that performs mechanical, biological and chemical filtration in one quiet, cabinet-hidden unit.

In detail: The Aquael Ultra is a user-friendly canister built around easy maintenance and reliable flow. Water is drawn down, pushed up through media baskets, and returned clean via the outlet or spray bar. With the motor and media outside the tank, it runs quietly and frees up space inside the aquarium. Pick the model to match your tank: the higher the number, the higher the flow and the larger the tank it suits. For example: on a 4-foot planted tank (around 200–250 L), the Ultra 1200 turns the volume over several times an hour, polishing the water and circulating nutrients evenly.

Tank-size ranges are approximate — size up for goldfish, cichlids or heavily-stocked tanks.

Key Features

• Three flow options (900–1,400 LPH) — a model for every tank from 3 to 5 feet.
• Generous multi-stage media baskets — room for mechanical, biological and chemical media.
• Quiet operation — motor sits in the cabinet, away from the tank.
• Easy-prime and easy-open design — Aquael builds the Ultra for simple, fast maintenance.
• Excellent value — canister-grade filtration at an accessible price.
• Tidy hidden design — frees the tank for aquascaping.

Benefits

Immediate: Clear water and strong, even circulation from day one, with nothing bulky in the tank.

Short-term: As the biological media matures, ammonia and nitrite stay at zero and fish colour up.

Long-term: Stable, healthy water for years at a budget-friendly price, with only inexpensive wear parts to replace.

How It Works

The Ultra runs water through three stages — mechanical foam traps debris, biological media grows the bacteria that convert toxic ammonia to nitrite and nitrate, and chemical media polishes the water. The sealed canister forces every drop through the media. See how aquarium filters work.

Suitable For

• Planted aquascapes (pairs with a spray bar and CO2)
• Community tanks of tetras, guppies, mollies, gouramis and barbs
• Lightly-stocked cichlid and goldfish tanks (size up for heavy stocking)
• Budget-conscious keepers who want canister-grade filtration

Not Suitable For

• Tanks over 450 L — step up to the Aquael Ultramax or Hypermax 4500 BT
• Nano and betta tanks under 60 L — use the Aquael ASAP internal filter or a sponge filter

Setup & Usage

Place the canister below the water line, load media in order (mechanical → biological → chemical), connect the hoses, prime, and switch on. Position the outlet or spray bar near the surface for oxygenation. Allow 4–6 weeks to cycle. See the installation guide.

Technical Specifications

Common Problems It Solves

Cloudy or yellow water: multi-stage filtration and a large media capacity clear debris and dissolved organics. Tight budgets: brings canister performance at a lower price than premium brands. Cluttered tanks: external filtration frees the tank for aquascaping. Frequent maintenance: the large canister means cleaning every 6–8 weeks.
