Seachem Tidal 110 Hang-On-Back Filter | up to 425L (4–5 ft+) | Fish Bazaar
The Seachem Tidal 110 hang-on-back aquarium filter is the most powerful HOB filter in Seachem's Tidal range, built for large fish tanks up to around 425 litres (roughly 4 to 5 feet and above), delivering a powerful 2,000 litres per hour with a very large media basket and a built-in surface skimmer. From Seachem — the brand behind Matrix and Purigen — the Tidal 110 hangs on the back of your tank, sets up in minutes, and rivals a canister for media capacity, making it one of the best large hang-on-back filters available in India.
What is the Seachem Tidal 110 Filter?
Short answer: A high-output hang-on-back (HOB) aquarium filter for large tanks up to ~425 litres, with a very large media basket, self-priming pump and surface skimmer.
In detail: The Tidal 110 is the flagship of Seachem's Tidal HOB range. It hangs on the rim and cascades filtered water back in, with a very large media basket that delivers canister-like capacity in a hang-on form. It self-primes, has fully adjustable flow, and includes a surface skimmer to clear the oily film on still water. For example: on a large 4–5 foot community or planted tank (around 300–425 L), the Tidal 110 powers through the bioload and keeps both the water and the surface clean — without the hoses and cabinet of a canister.
Key Features
- 2,000 LPH adjustable flow — the strongest flow in the Tidal range, for large tanks.
- Very large media basket — canister-rivalling capacity, fill it with the media you prefer.
- Built-in surface skimmer — removes surface film and improves gas exchange.
- Self-priming pump — starts easily with no manual siphoning.
- Easy maintenance — maintenance alert and tool-free media access.
- Seachem-engineered — from the brand behind Matrix and Purigen media.
Benefits
Immediate: Strong, even circulation, a clean surface and clear water on a large tank from day one.
Short-term: The very large media capacity matures into a powerful biological filter, keeping ammonia and nitrite at zero even on bigger, busier tanks.
Long-term: Canister-grade results with HOB convenience, for years, using only inexpensive media top-ups.
How It Works
The Tidal 110 draws water up through its very large media basket — mechanical foam traps debris, biological media such as Seachem Matrix grows the bacteria that convert toxic ammonia to nitrite and nitrate, and chemical media such as Purigen polishes the water — then returns it over the surface skimmer.

Which Tank Size Is the Tidal 110 For?
Short answer: Large tanks up to around 425 litres — roughly 4 to 5 feet and above.
| Tank length | Approx. volume | Tidal 110 suitability |
|---|---|---|
| 4 ft | 200–250 L | Good (consider the Tidal 75) |
| 5 ft | 350–400 L | Ideal |
| 5–6 ft | up to ~425 L | Excellent |
| Above 425 L | 425 L+ | Step up to a canister filter |
Suitable For
- Large community tanks of tetras, guppies, mollies, gouramis and barbs
- Planted tanks (the surface skimmer keeps the surface clean)
- Cichlid and goldfish tanks within its size range (strong flow handles waste)
- Keepers who want canister-level capacity without a cabinet
Not Suitable For
- Tanks over ~425 L — choose a canister such as the Fluval 407
- Nano and betta tanks — the flow is far too strong
- Rimless tanks where a HOB cannot hang securely
Setup & Usage
Hang the filter on the back rim, fill the media basket (mechanical → biological → chemical), prime it, and switch on. Set the flow and adjust the surface skimmer. Allow 4–6 weeks to cycle. Rinse the mechanical media in old tank water every 2–4 weeks. See the installation guide.
