The Pond Guy AllClear G2 Pressure Filter & Ultraviolet Light Clarifier & Pump Combo, Pressurized External UVC Bio & Mechanical Filtration with Backflush System, AllClear G2 4500 & SolidFlo G2 3600

After trying three different other types of pumps finally, I bought this one and it works beautifully no regrets. I recommended 100%.

Easy to use and clean

I tried for years to find a filter that really really worked . This one is amazing I highly recommend it

This set-up is awesome! I have a 4,000 gallon koi pond, with a heavy fish load. I have been running a large up-flow bog filter and a large bead filter. Those are good but I needed a little extra. Once I installed this AllClear canister and pump, my pond went Cristal clear within 48 hours.I highly recommend.

The media could not be loaded. Working well.

The media could not be loaded. Our old filter died leaving our pond a grotesque thick algae mass. Within three days and four back washes our pond has never been clearer. The pump is plenty strong enough to push the water from one end of the pond where the lily pads are up through the hard PVC pipe back around to the pump which is then split off to two separate waterfalls. Even with the pond dye you can see how clear the water is.

I have two of these combos, one being the G2 3500 with SolidFlo G2 2650, and the most recent the G2 4500 & SolidFlow G2 3600. I run both setups in my pond, about 3000 gallons, which stocks 11 Tosai Koi (ranging from 8" to 3") and two Sarasa Comets (~10").My honest view on these pumps and filters.1. These are expensive!!They are basically copies of the Filtoclear range from Oase and the pumps are copies of Oase's Pondtec. That does not make them "bad", in fact, my first setup did so well I decided to upgrade to the largest filter and pump combo. From my experience, these are made really well and have not leaked and or cracked. Which is something you read often with the "cheaper" alternatives, especially the pressure filters.2. The UV is under powered, they work OK, but the wattage (9 watts), in my opinion, is not enough to really keep up with larger volumes of water. My pond is ~ 3000 gallon and I use BOTH setups 24/7 and without additional filtration (biological) these filters will not keep the water "clear" at all.3. As mentioned above, these filters are great for "mechanical" filtration! I would NOT use them for biological filtration. In my case, I run each setup from pump to the pressure filter for mechanical filtration, then exit the pressure filter into Bakki showers. The Bakki showers house a ton of surface area for biological filtration. Previous to using my Bakki showers after the pressure filters. The pond was green, there simply was not enough biological filtration to tackle and combat the algae, even with both UV's powered and running 24/7. (This goes back to point #2 above). So think mechanical if you are stocking larger fish, or a higher number, especially if you have Koi!4. These are easy to clean, I love the backwash option and using the handle to compress the filter media (sponges). Cleaning is rather quickly! I clean the filters once a week and use this as a method for doing water changes as well, so I get two for one!Overall, I think you could easily save a lot of money and buy a "similar" setup.As I mentioned, I've not had any issues with quality as well as durability. So perhaps the "extra" money spent goes to the overall durability and quality! By all means, that is great as other setups could have you replacing faulty filters. However, I also feel the media and UV needs to be replaced every year if not 2. This can get costly overtime as well!TLDR: If you are stocking Koi, YOU WILL NEED MORE FILTRATION, and that filtration being Biological. These sponges just do not house enough to colonize a healthy amount of biological filtration!!!! They are amazing for mechanical filtration. The Pumps handle Solids without issue and the UV is under powered for ponds with larger volume.

Guys so far it’s working wonderful like the design of it let’s wait and see if it won’t leak after a little while
