So as I was upgrading to a bigger pond I wanted/needed to add extra filtration I immediately wanted this filter. I set up the new pond with the pressure filter, I had filled the new pond 5 days before adding the fish and filtration during the heatwave so in those 5 days the water went dark green, the pressure filters uvc did a great job at clearing the grean colour but then the uvc bulb went, so I decided I would sort this filter out, it is so simple to set up, add the hose from the pump, plug in the filter for uvc and its ready. I have included 2 photos, the first photo was taken at about 5pm yesterday afternoon just after setting up the new filter, the pressure filter is not attached at the moment so it is just this filter on the pond, I have just taken the 2nd photo at 9.30am the next morning, as you can see the clarity is amazing 16 hours after turning the uvc on and the sponge in the filter collecting the floating dead algae, I can even see new buds on the lily. Being a new pond there will always be algae problems, this is expected and to be honest I welcome it as it allows the pond to come to life, eventually I hope to have what I call a green carpet on the floor and walls of short length algae, the fish love feeding off of the life that makes this algae home but I do like to see the fish so I like to have the best of both worlds and give the fish a good life and this filter gives me exactly what my fish and I would like. The new pond can have 700 gallons but at the moment I have 500 gallons in it and this filter can handle that volume fine, I also only have a few fish so the waste level is low, I will be adding 2 or 3 koi in time but the filtration needs be a lot more as koi create a lot of waste but I will also have a smaller quartine/hospital pond and this will be perfect for that. If you need a small filter to run 500 gallons or less then you will not regret getting this filter, it is so easy to set up, very easy to maintain, it keeps the water in great condition, you can add extra mechanical and or biological media, the filter is supplied with one layer of coarse foam sponge for the removal of particles and came with ceramic rings as the biological media as the ceramic media holds a large amount of nitrfying bacteria and there is room to add extra sponge layers and ceramic rings or even change the media to whatever you want and this filter is extremely good value especially when you think the uvc is included, it does not come with a plug fitted but adding a plug takes a couple of minutes but it gives you the option of how you power the filter, I just use a plug as it does not need high power to work. The pump I am using is a 1000 gallon per hour but the filter can easily handle a stronger flow. Would I recommend this filter - the answer is simple - yes, it is so easy and is great if you want it for your first or tenth pond.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic filter *by M***Y on 24 July 2025* My mother bought one of these filters in the 90's and it never failed, just changed the uvc bulb yearly and did regular maintenance and it really was a great little filter.
