Exceptional filtration in aquariums up to 75 US gallons (300 Liters)~ 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.~ Fully adjustable flow regulationFully 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 skimmerThe 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 flowWith 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.~ Maintenance alertOver 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.~
