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

Very efficient filter, gives great water clarity and easy to install.

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.

After persevering with a crappy pump and separate UV filter for a few years, we bought this replacement and was amazed at the difference it made to the clarity and healthiness of the water. Even our waterlilly is looking lush and healthy- the irises produced loads of flowers this year, and we had way more frogspawn mature into frogs since installing it!! Everything is flexible about it, and it’s quite powerful- you can easily attach a waterfall pipe if you wanted, we use that exit to circulate and aerate the pond better. We clean it every week or so, and it works well. Wish it had some kind of handle to make it easier to pull out from the centre of the pond.. so we attached a handle made from cable ties fed through the lid, and use a rubbish picker to draw it to the edge with my makeshift handles - make it much more easier to lift as it’s heavy when it’s full of water👍

I had an Easyclear 3000 for a couple of years. When I increased my pond size to around 2000 litres, the water started turning green so I sought a more powerful filter pump. The All Pond Solutions CUP-311 is very powerful and cleared most of the green water within a week. One nice feature is the UV light has an indicator on the outside of the case so you can tell if the bulb has blown without having to take the casing apart. The filter is easy to clean, there is a very large sponge than spans the entire case and underneath it are 2 boxes of stones and 1 box of plastic pieces. There are 3 different fountain heads, I am currently using a waterfall. Overall, I am extremely pleased with my purchase of this filter, nothing has yet gone wrong. I've had it running for 2 weeks, my pond is clear and fish have all come out of hiding and seem happy. The only mild critique I have is that no plug was fitted or provided, I had to scavenge one from an old pump.

Excellent pond pump, filter & fountain.

It is brilliant & powerful, keeps water clear. Easy to clean

CUP311I have had three different makes and types of filter for my smallish pond in the past.. all with uv but all BEFORE this one hard or flimsy to get apart.. I love the solid clips on the casing.. everything fits well and the UV works and I can see the light from the surface - excellent - happy relaxed fish 😊 I have the fountain on mushroom which is a gentle flow and fairly quiet.. also love the fact there is one cable and after adding a plug ready to go.. unlike other makes which are so complex and double lead - well done All pond solutions - and it’s better more solid good uv size 11w and much cheaper than others by a long way! Can’t go wrong! Lovely clear water in a day even after repotting plants in baskets which caused a little soil spill - I’m very happy! After 5 months and a bit of algae appearing I have replaced UV bulb - was dreading working out how to do it - dead easy - no problem just need a screwdriver to undo locating screws on unit replace bulb screws back in - I’m chuffed with myself - other pumps I’ve had have been a nightmare Since previous review I’ve bought CUP305 which is smaller but just as good and efficient for a smaller pond

Nachtrag 20.05.2019 Ich habe die blaue Filtermatte getauscht gegen ein selbstzugeschnittenes Produkt (Filterwatte für Aquarienfilter [80x25x3, passt so grad noch von der Breite]). Ich bilde mir ein, die Filterleistung was Kleinstschwebeteilchen anbelangt, ist damit besser. Siehe drittes Foto, Sichttiefe jetzt gemessen mit 70 cm (fehlen noch 20cm, ist mir aber egal). Die Pumpe hat deshalb jetzt alle Sterne verdient. Die Bitterlinge sind jetzt ganz gut zu beobachten. Man muss nur ein paar Minuten ruhig stehen bleiben, dann kommen sie und flitzen rum. Nachfolgend Erstbewertung vom 9.05.2019 (mit damals 4 Sternen): Zunächst mal was zur Pumpe selbst, der Zusammenbau war einfach. Deckel entfernen, die drei Filterkammern in ihre Halterungen stecken. Deckel wieder drauf, Teleskoprohr zusammenschrauben, die beiden Drehregler so stellen, dass der Wasserstrahl sauber noch oben durchläuft und dann noch das Teleskoprohr aufschrauben. Filterpumpe in das Wasser tauchen, ein paar Mal kippeln um Luft rauszulassen, hinstellen und Schukostecker rein. Die Reinigung gestaltet sich bislang ebenfalls einfach, neben den drei Filterkammern lässt sich auch der Pumpenmotor einfach entfernen und damit reinigen. Die UV-Lampe scheint aber mit Schrauben am Gehäuse fixiert zu sein, weiß noch nicht genau wie hier eine Reinigung möglich ist. Nach ca. 1 Woche war der Teich deutlich sauberer. Jedenfalls das Grün-/Schwebealgen-Zeugs ist m.E. weg. Sicht ist deutlich besser geworden. Aber von einer Sicht bis zum Teichgrund bin ich immer noch weit entfernt. Das Teichwasser scheint jetzt statt stark grünlich (vorher) jetzt leicht gelblich zu sein. Siehe Fotos. In den dunklen tiefen Bereich sehe ich nur etwa 40 cm, dann ist Schluss. Ist dass, weil ich so ein enges tiefes Loch habe oder weil ich keine Teichfolie sondern einen Lehmteich habe. Oder wird das auch noch besser. Ich habe seit Jahren jede Menge Lurch im Teich, manchmal auch einen Frosch. Jetzt habe ich 8 St. Bitterlinge eingebracht, welche ich noch nie gesehen habe. Pflanzen hätte ich auch genug meine ich. Wenn ich den Arm reinstrecke, bilde ich mir ein, der ganze tiefe Boden ist voll davon. Richtig gesehen habe ich die untersten Pflanzen auch noch nicht so richtig.

Completo filtro spugna l’acqua diventa cristallina in un paio d’ore

La lámpara UV se ha fundido a los 6 días de funcionamiento.

Très bon Produit, tout du moins au premier abord cela paraît très solide, emballage au top comme d’habitude avec Amazon, la pompe se branche directement avec les files et non pas par une prise normal même si celle-ci peut être adapté ensuite. Je l’utilise dans un petit bassin et en deux jours l’eau est devenu nettement plus clair, je pense qu’il faut environ une semaine Pour avoir un résultat parfait. Très content de mon achat, de la livraison, de l’emballage, je recommande car à ce prix c’est un bon produit.

Super produit je recommande Mon bassin etait plein d’algues en suspension et boueux. Toujours à traiter contre les algues ce produit à révolutionné ma vie. Au bout de 3 jours mon bassin de 800L à retrouvé une eau parfaitement claire. Produit Livré avec une prise et parfaitement opérationnel. Conseil : nettoyer le filtre tous les 2-3 jours au debut (2-3 semaines) Moi maintenant je nettoie le filtre 1 fois semaine -> résultat nikel !!
