Sobo WP-208H Hang-On Filter | Turtle & Small Tanks (up to 50L) | Fish Bazaar

The Sobo WP-208H hang-on aquarium filter is a compact, affordable hang-on-back (HOB) filter designed to work even at low water levels, making it ideal for small fish tanks up to roughly 50 litres and especially for turtle and terrapin tanks where the water sits below the rim. It hangs on the back, returns filtered water over the surface, and provides simple mechanical and biological filtration at a budget-friendly price — one of the most practical small and turtle-tank filters available in India.

What is the Sobo WP-208H Filter?

Short answer: A budget hang-on-back (HOB) aquarium filter built to run at low water levels, ideal for small tanks up to ~50 litres and turtle tanks.

In detail: Many hang-on filters fail when the water drops below the rim — common in turtle tanks, which are kept part-filled. The WP-208H is designed to keep working at lower water levels, drawing water through a filter cartridge and returning it over the surface. It is easy to install and clean. For example: on a part-filled turtle tank or a small nano tank, the WP-208H keeps the water clear where a standard HOB would lose its prime.

Key Features

• Low-water-level operation — keeps filtering even when the water is below the rim, perfect for turtles.
• Compact hang-on design — small footprint behind the tank.
• Mechanical + biological filtration — traps debris and grows beneficial bacteria.
• Surface return — aerates and circulates the water.
• Easy maintenance — simple cartridge access.
• Budget-friendly — practical filtration at a low price.

Benefits

Immediate: Clear water and circulation from day one, even in a part-filled tank.

Short-term: The media matures into a biological filter, helping control waste from messy turtles and small fish.

Long-term: Reliable, low-cost filtration for turtle and small tanks, with cheap and easy media changes.

How It Works

The pump draws water through the cartridge — mechanical media traps debris and biological media grows the bacteria that convert toxic ammonia to nitrite and nitrate — then returns it over the surface, working even at reduced water depth. See how aquarium filters work.

Which Tank Size Is the WP-208H For?

Short answer: Small tanks up to about 50 litres and part-filled turtle tanks.

Suitable For

• Turtle and terrapin tanks kept at low water levels
• Nano and small fish tanks
• Budget and beginner setups

Not Suitable For

• Tanks over ~50 L of fish stocking — choose a larger HOB or canister
• Heavily-stocked tanks — limited media capacity (for messy turtles, pair with a canister)
• Rimless tanks where a HOB cannot hang securely

Setup & Usage

Hang the filter on the back, fit the cartridge, prime it, and switch on — it will keep running at reduced water depth. Rinse the media in old tank water every 1–2 weeks for turtle tanks (which produce more waste). See the installation guide.

Common Problems It Solves
