(in terms of tubing fitting?** A: I'm unsure regarding size fitting but what I can say is this is the best uv filter I have had, I would just get it and try it out. Very easy to assemble . Good luck **Q: Will this qork on a fluval 307** A: Assuming Fluval 307 is your filter it should work if you you fit it in the pipe to the input side between the pump and the filter. Mine is fitted there feeding to a home built lave rock filter and it works really well. Pond is 4500litres if that helps. **Q: Where can i get spare bulbs for CUV-211?** A: At most aquatic shops. standard type bulbs. **Q: Hi, what size is the thread on the unit which the hose tail attaches to?** A: No idea of the thread size on the unit which holds the "tail", I don't need to know. The hose tail is cot to suit hose diameter, the hose is pushed on and held with a jubilee clip. ( Warm the hose end in hot water, to make it more pliable to push on. It will also shrink back slightly to grip the hose tail). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clears algae quickly *by B***S on 21 April 2026* Seems great so far - it has converted pea soup to cloudy lemonade in the space of a week. Presumably it will do better still when I get round to putting a filter in the loop. ### ⭐⭐⭐⭐⭐ Excellent quality *by K***N on 13 May 2026* Great product workswell ### ⭐⭐⭐⭐ A good solution for a small/medium pond. *by S***R on 4 March 2026* I had an algae problem in my fish pond and was recommended a UV light steriliser to plumb in inline with the filter that I already had. This seemed to fit the bill and was good value for money compared with others available online. It was delivered promptly and on un-packing it is clearly high quality. There are not many parts to fit, you will need to cut the fittings to size for your hoses and secure them with hose clips. Otherwise the assembly is easy enough. Once up and running, it is simple to keep clean and you can just rinse it out as and when you clean the filter on your pond or tank. ## Frequently Bought Together - allpondsolutions 11w UV Light Steriliser for Pond & Aquarium - CUV-211 Fish Tank Pond Clarifier - Helps Remove Algae and Greenwater - Pisces Twin Pack 11w (watt) PLS Replacement UV Bulb Lamp for Pond Filter UVC --- ## 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.at/products/49066396-allpondsolutions-11w-uv-light-steriliser-for-pond-and-aquarium-cuv](https://www.desertcart.at/products/49066396-allpondsolutions-11w-uv-light-steriliser-for-pond-and-aquarium-cuv) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-03*
