It comes with the pump. But, you'll have to replace them eventually. The sponge can be washed and reused. **Q: Where can I buy the UV light to replace (spec. says it lasts 10,000 hours)?** A: It is a 5W G23 UVGI Bulb. You can find them on Amazon or e-bay. **Q: What are the dimensions of the filter baskets?** A: Roughly 3.5"w, 2"d, 2"h.......Obviously Bio media isn't an issue, and any carbon media bag works for the center basket, but the trick is the sponge. I buy fluval 30 size media sponges, cut them in half and turn them sideways and they fit perfect. Somewhat of a pain, but depending on the quantity of fish in your tank, you shouldn't need to replace your sponge but once every few months. And rinse it out about every 20 days or so **Q: where are the part numbers for the replaceable filters and UV** A: I can tell you the part number which is WTCUH5L. Made by Grech , it’s a 5 watt UV light. So far I have been unsuccessful finding a US source and or equivalent. I’m still looking just in case. ## Customer Reviews ### ⭐⭐ doesn't last for long tine the motor burns *by R***P on 13 September 2024* I have a fluval hang on filter it is still running fine but this filter motor burns in short time and is of no use ### ⭐⭐⭐⭐⭐ Good UV filter. *by N***K on 6 May 2025* Very effective at dealing with algae. Noiseless, good LPH and with a large filtration chamber, one can use the media of ones choice. But a bit expensive. Should have been priced less than 2k. I have 12 aquariums (yes, I am crazy!), if it would have been less expensive, I would've bought for all. ### ⭐⭐⭐ Disappointment *by K***C on 23 November 2023* After fixing it in my fish tank I found that the bottom of the filter is leaking and can't fix it. ## Frequently Bought Together - Grech CBG-500 5W UV Sterilizer Hang-On Back Filter, 10-30 gallon/132 GPH - AquaClear 50 Foam Filter Inserts, Aquarium Filter Replacement Media, 3 Count (Pack of 1), A1394 - Grech CBG-800 5W UV Sterilizer Hang-On Back Filter, 20-50 gallon/211 GPH, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/294863651-grech-cbg-500-5w-uv-sterilizer-hang-on-back-filter](https://www.desertcart.ma/products/294863651-grech-cbg-500-5w-uv-sterilizer-hang-on-back-filter) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-05-17*
