TIDAL hang on filters are designed from the ground up to provide the aquarium with high-quality, easy to implement, comprehensive filtration. While having a system plumbed with an overflow and sump certainly has its advantages, this isn’t always practical. In some situations, space constraints or aquarium size can make this a challenge. Hospital and quarantine tanks are great examples of systems that may need to be set up quickly and with minimal equipment. For simplicity’s sake and for ease of maintenance, HOB filters are a great option in these situations. They are easy to use and adaptable to a variety of aquarium conditions. The Tidal filters can be set up in seconds by hanging them right on any open side of your aquarium.


HOB filters will add flow to your tank encouraging gas exchange while trapping suspended detritus for removal. The adjustable intake depth lets you create the perfect motion throughout the tank to sweep particulates into the filter for removal. With the addition of pre-seeded bio-media you can also instantly add biological filtration and prevent the buildup of toxic by-products. The generous media basket area also allows for the use of chemical filtration such as activated carbon which can be useful for removing medications or general water polishing, making this a very compact and versatile filtration solution for small to medium-sized aquariums.

Product Questions

For a 60-gallon breeder would this work well or would you get a bigger filter?
Question by: Tony on Jan 1, 2024, 3:06 PM
For a freshwater aquarium this would be a fine size filter, however for a saltwater I would recommend something larger.
