Ventilation slots

Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.

Bottom-to-top flow

The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.

Maintenance alert

Over time, filtration media can become clogged with detritus reducing or obstructing the flow of water through it. When this happens in Tidal™ filters, water is redirected around the filter and back into the aquarium through an outlet on the side. The redirected water pushes up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.

Surface skimmer

The surface skimmer will capture the water from just below the surface, where excreted fish oils accumulate, as well as deeper in the tank removing floating debris

Telescoping intake pipe

The adjustable telescoping intake allows water to be taken from any level of the tank without the need to stop the filter or bother with spare parts

Flow regulation

The flow on the pump is adjustable using the dial on the front

Intake flow regulation

A dial on the side of the filter adjusts how much flow comes from the underwater intake versus the surface skimmer

No filter cartridges

The filter basket has a huge capacity to hold filtration media of your choice in the configuration of your choice. All Tidal™ Filters come with Seachem's Matrix™ bio-media to get you started.

No mess maintenance

The basket is fully removable and snaps into the lid of the filter for easy and drip-free transit to a sink or hose for cleaning.

Self-priming pump

Self-priming pump means there is no need to fill the filter basket with water, start a siphon, monitor the filter, or any of the other headaches of starting a new filter

Self-cleaning impeller

The self-cleaning, corrosion-proof impeller is suited for both saltwater and freshwater environments. This cuts down on maintenance and makes the filter suitable for a wide range of environments.

Adjustable leveling device

A leveler on the base of the filter lets the filter adjust to a variety of aquarium styles

Heater holder

A heater can be attached to the side with an optional heater clip, allowing for better dispersal of heated water through the aquarium.
