allpondsolutions CUP-311-2500L/H All in One Pond Pump Filter with Fountain and 11w UV Steriliser, Clear Water Algae Control for Ponds up to 4000L

The media could not be loaded. Pond filter installed into pond. Perfect size for my pond. Cleared my water within 2 days. Has great features to include a very squirty fountain that my kids enjoyed. Instructions can be a bit hard to understand. I couldn't work out how to check the bulb however so hope it works. Comes with three mediums for filtration. Also has a spare propeller so dont do what I do and try to connect this. It doesn't need the pump opening. Plug and go. Just wash the foam and medium in pond water to keep the beneficial bacteria

We had the same model of pump at least 25years ago and it has run not stop with no problems all that time. So when it finally needed replacing we were so pleased to see that pump was still available. We cleaned out the pond and put in the new pump and the water is now perfectly clear and the fountain bubbling away beautifully. The secret is to renew the light when recommended and clean out the filters from time to time. I would highly recommend this pump to everyone.

Bought this a month ago and have just installed it. My fish pond is small, under 2,000 litres, and has some oxygenator plants in it for the handful of small goldfish I was given this year. I noticed the water was cloudy and I couldn't see the bottom of the shallow end of the pond due to algae build up.Having read the reviews here and seen photos/videos, I'm hoping this filter/pump will clean the water. I'll give it a few weeks and update progress.One final point. I'm grateful to other reviewers mentioning there's no plug included.

Easy to use looks like it's working brilliantly

Works extremely well

My pond had been in place for 13 years and I had to replace the liner 4 years ago. In all that time I have attempted to maintain the pond without any type of filter. For the first year or so I could see to a good depth. Then the algae started to take over.Even after the liner replacement, visibility was minimal as I tried to reuse some of the water to maintain a bacterial balance.To help matters I've used various potions which have clumped the algae together and I've skimmed the surface. They've helped a little bit not greatly.This year the fish were only visible at the surface and the algae appeared more luminous than in past years.I finally caved in and bought this all in one unit.It arrived promptly from All pond solutions (and they answered a query swiftly).It's very well designed and a sturdy device (although opening the UV sleeve to check for breakages is a bit heart stopping). It's also very easy to open up and clean.I didn't have round-the-clock access to power so, while waiting for an electrician to install a more permanent solution, I wired a plug to the unit and ran it 10 hours a day for a week connected to an extension reel.I noticed some improvement in the water clarity and had to clear the filters 2 or 3 times but the weather turned and prevented me from running it this way any more (extension reels and rain don't play well together).The electrician eventually arrived and fitted an outside socket for me.The filter was now running 24/7.I was initially disappointed to see little improvement after 4 weeks despite having to regularly clean the filters. Surely it would be improving or did I have too many fish to be able to expect water clarity? The unit isn't at the bottom of the pond - could that be the reason?Then suddenly at the 5 week mark, I noticed a marked improvement! I could see creases in the liner and even an outline of the filter unit.It's now another week on and things have improved further and I can see practically to the bottom of the pond. The fish appear to be very happy.Obviously there was a lot of sludge in my pond from years of decomposing lily pads along with fish waste and algae.There is still some way to go as, even though the water now appears clear, every surface (even the filter box and the hosepipe used to circulate filtered water) is quickly coated with a green layer hours after the unit is resubmerged after cleaning.But I'm still at the stage of cleaning the filters weekly so I know that the clarity will increase and the residue will reduce further.I would certainly recommend this unit. Just be aware that it can't be hurried if your pond has been in place for a long time but it WILL do the job eventually.

I have a nature pond after a heron stoll our goldfish many years ago. We have always had frogs breeding in the pond and even a few newts. I used to have a small pump feeding a waterfall but water got into the junction box and was tripping the electrics so got disconnected. After years of neglect the water had turned to pea soup and this year none of the frog spawn survived.After a couple days of switching on this pump, the water cleared and I see we have around 20 frogs and about 30 newts (this might be why we lost the frog spawn). I have now removed the excess sludge, carried out a partial water change and the pond looks brilliant and crystal clear.The filter is easy to clean and the manual is very detailed. The build quality looks good and would imagine this will last for a number of years. The UV indicator is not easy to see and can only be seen in the dark. I assume this is for safety and to protect against UV exposure as the indicator looks directly at the lamp. Not sure about the science. It comes with a number of baskets containing media for the bacteria to grow but it contains a UV light, which kills bacteria good and bad. The pump comes with a generous length of flex.I have bought spare impellers, filters and UV lamps so I have spares for the next couple of years.Please note that the pump does not come with a plug. This is understandable because it requires either an outdoor socket or as in my case, hardwired into a waterproof junction box. Even if the cable is long enough to reach the house you would still have to cut the plug off to get it in the house. After reading other reviews I am horrified to read someone actually had an electric shock when a seal failed. Speaking as a qualified electrician, the pump must be protected by a RCD, so if the circuit is not RCD protected, an RCD plug must be used.Highly recommended purchase.
