It features a powerful 525 GPH flow rate and a built-in 9W UV sterilizer to ensure crystal clear water by controlling algae and bacteria. With four large media baskets, it offers customizable filtration options, all in a compact design that fits easily into your indoor space. ## 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.

Highly recommended. ### ⭐⭐⭐⭐⭐ Buen filtro a precio muy accesible *by R***O on 1 September 2023* En particular este modelo HW-704B 525 GPH tiene materiales de mejor calidad, trabaja muy bien y mejoro la condicion de mi acuario ### ⭐⭐⭐⭐⭐ Great Value *by Y***U on 14 August 2020* After reading some reviews on Amazon and watching a few YouTube videos on the SunSun HW-704(B), I decided to purchase one for my 30 gallon tank. The unit was shipped out quickly and arrived in good condition. It seems that SunSun must have also quality checked the canister for leakage since the filter sponge was slightly moist. I am pretty happy with it and bought another one for a new 50 gallon tank a few months later. Although I only use it once or twice a week, it's nice there is a UV sterilizer light to sanitize the water. Some people seem to have issues with the light damaging the plastic trays, but this seems to be a problem only if the light is turned on all the time. I didn't see this as a defect, but took it as something to keep in mind since the heat from any light placed next to plastic can cause it to degrade over time. There is also a small indicator light on the top of the canister to let me know that it is working. The build on this seems pretty good. The outside of the canister is sturdy and it fits between the legs of my 29 and 40 gallon metal Imagitarium tank stands from Petco. The green hose can be fitted onto the inlet and outlet by softening the hose - just dip each end into hot boiled water for a couple of seconds before slipping it over one of the canister's nozzles. Once it cools, the opening will contract to form a nice tight seal. I have not had any issues with leakage using this method. Note that there is a round orange sticker at the bottom of the inside of the canister. Use this as a reference when placing the baskets back inside. Make sure that the orange sticker aligns with the holes of the baskets. This is to ensure that the light is properly situated so that the UV light will work. This is a small but thoughtful touch on the part of the manufacturer. The unit is pretty quiet. If you are used to the sound coming from a hang-on-the-back filter, you will probably be happy with the reduction of sound from this canister filter depending on how you set up the return pipe. The pipe on my tank is set up to release the water back into the tank below water level to minimize splashing sounds. When I had a questions about the canister, I reached out to the seller who promptly responded and helped me. I am very happy with my purchase and the customer service and would not hesitate to buy the filter from this seller again. ## 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 - CNZ® Aquarium Filter Media Kits (Double Pack) - Activated Carbon, bio Ball, Ceramic Ring --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/472289008-sunsun-sun-hw-704b-525-gph-5-stage-external-canister](https://www.desertcart.sn/products/472289008-sunsun-sun-hw-704b-525-gph-5-stage-external-canister) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
