I can't find any information** A: Yes, my pond is 250 gallon and it worked fine. It started to clear after 3 days took roughly 7 days to clear completely, probably down to how much water you're pumping through it. Important if you're relying on this bio type filter to clear ammonia & nitrites from the pond. You will need to use the existing media that's holding bacterial from your old bio filter if possible with the new media until both types of bacteria take hold of your new media. You can buy booster packs of this bacteria if needed. Hope this helps. **Q: how much water will this model deal with** A: not to sure. I presume 2500 litres. my pond is 1400 litres and it is now crystal clear. I did however drain and refill it before I started as it was completely green. however it has been crystal clear since I did it. I would recommend this product to anybody. **Q: what size uv bulb for a 2500 g uv filter** A: I have a16w uv bulb in my filter and it works brilliantly no problems ## Frequently Bought Together - Fish Mate 2500 GUV Gravity UV Plus Bio Pond Filter - Pisces Double Wire Hose Clips to fit 25mm (1in) Pipe - Pisces 1in (25mm) Corrugated Black Flexi-Hose (by The Metre) --- ## 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.us/products/51885824-fish-mate-2500-guv-gravity-uv-and-bio-pond-filter](https://www.desertcart.us/products/51885824-fish-mate-2500-guv-gravity-uv-and-bio-pond-filter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-18*
