Tidal™ Power Filters are designed from the ground up to provide your aquarium with high-quality, comprehensive filtration. They are easy to use and adaptable to a variety of aquarium conditions. With a host of features including a self-priming pump, dual water intake with surface skimmer, adjustable flow, maintenance monitor, self-cleaning impeller, and a filter basket that holds any kind of filtration media – and more of it – Tidal™ Power Filters are designed to deliver the highest water quality possible with maximum versatility and ease of use. Features Fully adjustable flow regulation 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. Adjust using the dial on the front, for a powerful full flow rate of 450 gallons per hour on the Tidal 110 down to a gentle 90 gallons per hour on the same filter.   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   Adjustable intake flow With Tidal’s dual intake, it pulls water in through the telescoping pipe below the surface and at the surface through the surface skimmer. Easily adjust how much flow comes from the underwater intake pipe versus the surface skimmer with the intake flow dial.   Not available on Tidal 35 units 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 Not available on Tidal 35 units 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.   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 The self-priming pump means there’s 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. This also means that after a power outage, the filter will automatically restart itself. Tidal 35/55 pump shown But wait…there’s more 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. 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. Self-cleaning impeller The self-cleaning, corrosion-resistant 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. 3 year warranty All Tidal™ Filters are guaranteed against defects of materials and workmanship for a period of 3 years from the date of purchase, except for the pump’s impeller. This can be extended to 5 years by registering your filter. The warranty covers the replacement of the defective parts.
