    Not much to say it is a wonderful filter and more people should get them, I\'m very satisfied with it.

    good job


    Beautiful shape and large enough capacity. Multifunctional, can be used in aquariums and ponds. Plug and play, powerful filtration, large capacity. The running noise is relatively small, I can accept it.

    Do a complete water change


    I’ve struggled to keep my pond clear for more than a week and its been two weeks now since i added this filter and the water is crystal clear. I did a complete water change theres only algae along the walls but it looks beautiful. So happy with purchase

    Thorough filtration and easy to clean.


    The filter was easy to set up. The different size attachments work well, just make sure the o ring is installed correctly. So far no issues with leaks in 4 months.

    Great Canister Filter for the Cost


    Ordered two of these for my ponds. Works great and easy to clean so far!


  • Q:
    I like to know if your 4000 Bio Pressure has handle that turns to clean the sponges or is it the type that you gotta remove and clean separately?
    You need to press the blue sponge, squeeze the sponge, and then switch to backwashing, and the sewage inside will come out.

  • Q:
    I don't understand or believe these reviews. I have this pump in a 1500 gallon pond with about 20 fish and 1 turtle. I can't see the fish and the pond is full of algae. The filter is one year old. I have done all the maintenance in the horrible handbook and use a 1 year old 2500 GPH pond pump.
  • Q:
