Lid turns into a tray for the media basket when doing maintenance Maintenance monitor alerts you when to clean filter

The large capacity design of the filter basket allows for any type of Seachem filter media, which can be interchanged and placed in custom configurations.

All Tidal™ Filters come with Seachem's Matrix bio-media and a foam filter to get you started. Adjustable leveling device Adjustable intake flow

Self-priming pump & self-cleaning impeller Optional heater holder The surface skimmer will capture the water from just below the surface, where excreted fish oils accumulate, and deeper in the tank removing floating debris.

Fully adjustable flow regulation adjusts performance to a specific aquarium volume, type, or provide an environment for fish which prefer more or less water movement or oxygenation.

Innovative Design 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.

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.

The pump is also insulated and silent, making it excellent for office or dining room aquariums, and has extremely low power consumption for the amount of output – the large Tidal 110 filter uses only 12 watts.

Over time, filtration media can become clogged with detritus and prevent water from flowing through.

When this happens in the Tidal Filter, water is redirected around the filter and back into the aquarium through an outlet to the side.

When this happens, the redirected water pushes up the blue maintenance monitor on the top of the filter, letting the aquarium keeper know that the filter media needs to be cleaned out.

The basket is designed with raised slots which catch detritus rather than allowing it to fall through back into the filter when flow is stopped. A heater can be attached to the side with an optional heater clip, allowing for better dispersal of heated water through the aquarium.
