The Seachem Tidal 35 is a compact hang-on-back (HOB) aquarium power filter designed for freshwater and saltwater tanks up to 130 litres. It features a submerged, self-priming pump, a customizable cartridge-free media basket, and a built-in surface skimmer.

Key Specifications:

• Tank Capacity: Rated for aquariums up to 130 litres.
• Flow Rate: Maximum output of 500 litres per hour controllable via an adjustable flow dial.
• External Dimensions: Measures 155 mm (L) × 130 mm (W) × 180 mm (H).
• Included Media: Comes pre-loaded with a coarse mechanical sponge and Seachem Matrix biological media.
• Warranty: Includes a 3-year limited warranty, extendable to 5 years upon registration with Seachem.

Standout Features:

• Self-Priming Pump: Because the motor sits submerged inside the tank, the filter starts automatically without manual priming and restarts smoothly after power outages.
• Cartridge-Free Media Basket: Water flows from bottom to top through a large removable basket that fits any custom filter media. The basket snaps into the lid for drip-free transport to a sink.
• Surface Skimmer & Aeration: A built-in surface skimmer clears oily film and floating debris, while an angled spillway promotes surface agitation and gas exchange.
• Maintenance Alert Indicator: A blue pop-up indicator on the top lid rises to signal when media is clogged and water is bypassing the basket.
