The Aquael ASAP internal aquarium filter is a compact, energy-efficient internal filter for small fish tanks, available in two models — ASAP 300 and ASAP 500 — for tanks from roughly 40 to 150 litres (1.5 to 3 feet), delivering 330 to 500 litres per hour. Trusted by hobbyists worldwide, the ASAP sits inside the tank, is simple to install and maintain, and provides reliable mechanical and biological filtration — making it one of the best small aquarium filters available in India for nano tanks, betta tanks, turtles and low-water setups.
What is the Aquael ASAP Internal Filter?
Short answer: A compact in-tank (internal) aquarium filter for small tanks of 40–150 litres that provides mechanical and biological filtration with adjustable, gentle flow.
In detail: The Aquael ASAP is a submersible internal filter built for reliability and ease of use. It mounts inside the tank with suction cups, draws water through a sponge cartridge that traps debris and grows beneficial bacteria, and returns it through an adjustable outlet that can also aerate the surface. Pick the model to match your tank: the ASAP 300 for nano and small tanks, the ASAP 500 for slightly larger ones. For example: on a 2-foot betta or shrimp tank, the ASAP 300 keeps the water clean and clear with a gentle, adjustable flow that will not buffet small fish.
Choose your Aquael ASAP model by tank size
| Model | Flow rate | Suitable tank size | Tank length |
|---|---|---|---|
| ASAP 300 | ~330 LPH | up to ~100 L | 1.5–3 ft |
| ASAP 500 | ~500 LPH | up to ~150 L | 2–3 ft |
Tank-size ranges are approximate — choose the model rated above your tank volume.
Key Features
- Two flow options (330–500 LPH) — a model for nano up to small 3-foot tanks.
- Compact internal design — sits neatly inside the tank, no cabinet required.
- Adjustable flow — dial the current down for bettas and small fish.
- Mechanical + biological filtration — the sponge cartridge traps debris and grows beneficial bacteria.
- Energy efficient and quiet — low power draw, simple submersible operation.
- Easy maintenance — quick to remove, rinse and refit.
Benefits
Immediate: Clear water and gentle, adjustable circulation from day one, with no external equipment.
Short-term: As the sponge matures into a biological filter, ammonia and nitrite stay at zero and small fish settle and thrive.
Long-term: Years of reliable, low-cost filtration for small tanks, with only the occasional inexpensive sponge replacement.
How It Works
The ASAP draws water through its sponge cartridge, which provides mechanical filtration (trapping debris) and biological filtration (housing the bacteria that convert toxic ammonia to nitrite and nitrate). The adjustable outlet returns clean water and can aerate the surface. For small tanks this two-stage filtration is usually all that is needed. See how aquarium filters work.
Suitable For
- Nano and small planted tanks
- Betta tanks (gentle, adjustable flow)
- Shrimp and small community tanks (fit a pre-filter sponge for shrimplets)
- Turtle tanks and low-water setups
Not Suitable For
- Tanks over 150 L — choose a HOB, top or canister filter such as the Fluval 107
- Heavily-stocked or messy-fish tanks — the internal media capacity is limited
- Keepers who want zero equipment visible inside the tank — consider a canister
Setup & Usage
Rinse the sponge, mount the filter inside the tank below the water line with the suction cups, connect the air intake if using the aeration feature, and switch on. Set the flow to suit your fish. Rinse the sponge in old tank water every 2–3 weeks. See the installation guide.

Expert Recommendation
For a nano, betta, shrimp or turtle tank, the Aquael ASAP is our top compact internal filter pick — reliable, adjustable and easy to maintain. Choose the ASAP 500 if your tank is near 150 L. Add a pre-filter sponge for shrimp tanks, and boost biological capacity with a little TCWS Bio-Media in the chamber if space allows.
