Seachem Tidal Filter 75 Exceptional filtration in aquariums up to 75 US gallons (300 Liters). Features 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
