Featuring a powerful 525 GPH flow rate and a 5-stage filtration system, it ensures superior mechanical, biological, and chemical water purification. Its integrated 9W UV sterilizer effectively controls algae and bacteria, while four customizable media baskets offer versatile filtration options. The compact external design maximizes tank space and simplifies maintenance with drip-free valves and easy-access trays. ## Description The new 2016 SUN HW-704B external aquarium Filter system utilizes a multi-stage approach to filtration. Filtering aquarium tank water through four (4) internal layered baskets filled with assorted filter media material provides extremely thorough biological, mechanical and chemical filtration. This canister draws water into the filter through an inlet tube and returns crystal clear water via an outlet tube (both supplied). the outlet tube is fitted with a spray-bar to help increase oxygen aeration levels within your tank. These filters are absolutely ideal for freeing-up space within your tank and provide a huge internal capacity for filter media, making them suitable for larger volume tanks. The four flexible media trays allow you to add other filtration media such as SUN activated carbons, ceramic rings or bio-balls (sold separately). by filtering your tank using the filter media, you will observe a vastly improved level of waste-free water through extremely strong biological purification. The filter's easy-access layered filter media basket's make it simple to customize your media choices to suit your aquarium and fish livestock needs. The built in UV sterilizer exposes passing water to lethal doses of Ultraviolet light, killing, sterilizing or otherwise irreparably damaging many micro-organisms. Your fish tank water is pumped past the UV light which is sealed inside a quartz glass sleeve which is designed to allow the maximum amount of UV to pass through the water. Maintaining the filter is very simple. The drip-free shut-off tap allows you to remove the filter and transport It away from your aquarium fish tank to an area more suitable for cleaning. Each filter media basket lifts smoothly out of the unit and can be easily rinsed through and returned to continue its operation. ## Features - 5 stages with 9W UV, 525GPH (2000Lph) - Good for up to 150 gallon fish tanks - Dimension: 12" L x 12" W x 18" H - Built in 9 watt UV sterilizer for controlling algae spores/bacteria and promoting clear water - 4 Large media baskets for all your media need ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015JMQRNC | | Allergen Information | Abalone Free | | Batteries Included | No | | Best Sellers Rank | #37,113 in Pet Supplies ( See Top 100 in Pet Supplies ) #2,349 in Aquarium Accessories | | Color | White | | Customer Reviews | 4.1 4.1 out of 5 stars (632) | | Date First Available | 16 July 2019 | | Item Weight | 8.26 Kilograms | | Item model number | HW-704B | | Number of Items | 1 | | Pet Life Stage | All Life Stages | | Product Dimensions | 38.1 x 49.02 x 30.48 cm; 8.26 kg | | Quantity | 1 | | Size | Pack of 1 | | Specific Uses | Indoor | | Voltage | 220 Volts | | batteries required | No | ## Images ![Sunsun Sun HW-704B 525 GPH 5-Stage External Canister Filter with 9W Uv Sterilizer - Image 1](https://m.media-amazon.com/images/I/71+D59-JVlL.jpg) ## Frequently Bought Together - Sunsun Sun HW-704B 525 GPH 5-Stage External Canister Filter with 9W Uv Sterilizer - AQUANEAT Replacement Canister Filter Pads Compatible with SUNSUN HW-304B/404B/704B/3000 CF500 Generic Filter Floss Aquarium Filter Media - CNZยฎ Aquarium Filter Media Kits (Double Pack) - Activated Carbon, bio Ball, Ceramic Ring --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/472289008-sunsun-sun-hw-704b-525-gph-5-stage-external-canister](https://www.desertcart.sc/products/472289008-sunsun-sun-hw-704b-525-gph-5-stage-external-canister) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-08*
