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.

Telescoping intake pipe

The adjustable telescoping intake on the Tidal 55/75/110 units allows water to be taken from any level of the tank without the need to stop the filter or bother with spare parts.
