The Seachem Tidal hang-on filter delivers exceptional filtration with ventilation slots and aeration grooves that maximize oxygenation and gas exchange.
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.
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.
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
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
The flow on the pump is adjustable using the dial on the front
A dial on the side of the filter adjusts how much flow comes from the underwater intake versus the surface skimmer
What it is. The Tidal 75, Seachem’s mid-size hang-on-back power filter, built with Sicce. One of four models in the range (Tidal 35, 55, 75 and 110) sharing the same self-priming pump and self-cleaning impeller design and scaling up in flow and media capacity.
Seachem’s own spec for this model. Rated for aquariums up to 75 US gallons (300 litres); flow rate 350 US GPH (Seachem’s own site rounds this to 1,500 L/h; a precise conversion works out closer to 1,320 L/h); filter basket volume 0.50 US gallons (1.9 L); ships with 350 mL of Matrix filter media.
Flow is adjustable, not fixed at the rated maximum. The largest model in the range (Tidal 110, rated 450 GPH) is confirmed adjustable down to 90 GPH on the same unit, and the Tidal line shares that mechanism across all four sizes.
Warranty. 3 years as standard, extendable to 5 years by registering the filter with Seachem.
Dual water intake with a surface skimmer, pulling from the surface and below it at once. This is what clears the oily film and floating debris a single-intake HOB filter leaves behind.
Filter basket takes any media, not only Seachem’s own: loose or bagged carbon, Matrix, filter floss, whatever the tank needs, on top of the 350 mL of Matrix it ships with.
Maintenance monitor flags when flow has dropped enough that the media needs attention, rather than leaving that to a fixed weekly schedule.
Self-cleaning impeller is built to resist the debris jams that slow a HOB filter’s pump down over time.
Seachem guarantees Tidal filters against defects of materials and workmanship for 3 years from the date of purchase, extendable to 5 years by registering the filter. The pump impeller is excluded.
