    Ultimate Medium Pond Kits feature the Piper HydroClean™ Pond Skimmer that is
    FISH SAFE and Remote Installation Capable



    The Piper HydroClean™ pond skimmer included with Ultimate Medium Pond Kits are fish-safe, provide multiple design options with its ability to be installed away from the pond, conveniently provides multiple plumbing options, and is the easiest medium pond skimmers to clean – never requiring you to put your hands in the water.


    Fish-Safe. The Piper HydroClean™ pond skimmer included in all Ultimate Medium Pond Kits is the only medium pond skimmer with an integrated 6″ round inlet pipe that eliminates the need for a weir door to achieve efficient and effective pond skimming.

    The weir doors found on virtually all conventional pond skimmers are essentially a “one-way-door” that can fatally trap your fish inside the pond skimmer. Those types of pond skimmers also use dozens of screws to hold the weir door faceplate onto the skimmer itself – and those same screws extend into the skimmer and pose a hazard to the fish that get trapped inside the pond skimmer. As the fish struggles with its capture – it often inflicts fatal harm to itself on those screws.


    Ultimate Medium Pond Kits Fish Safe Pond Skimmer



    With the Piper HydroClean™ pond skimmer included in all Ultimate Medium Pond Kits can your fish swim in and back out again with ease – and with no screws inside the pond skimmer – there is nothing that can pose a danger to your beloved fish.

    Typical Medium Pond Kits Feature Hard-to-Clean Non-Fish-Friendly Pond Skimmers


    Typical Medium Pond Kits Come with hard to clean pond skimmers

    Typical medium pond kits include pond skimmers that require you to get down on your hands and knees, reach deep into the water inside the pond skimmer and pull up the debris filled net or plastic basket and heavy, smelly, saturated filter pad. Not only heavy and foul-smelling, these items will be filled with algae, fish poop, dead insects, dead worms, and all kinds of debris you wouldn’t want to touch. You could pay a professional to do this you, but that adds to the cost of ownership of your pond.


    There are many medium pond kits that feature filter pads down inside the pond skimmer … under a leaf net or basket. This requires you to first remove the leaf net (or leaf basket), then get down on your hands and knees to reach down 10″-12″ under water to pull the saturated filter pad out for cleaning. No joke. Look at the montage photo here on the right. These photos are from the internet showing you how the skimmers included with their medium pond kits get cleaned. We found them online …. you can too.

    Why would anyone want a pond skimmer that requires this kind of servicing?
    Do some people enjoy knee and back pain?

    Typical Medium Pond Kits with Difficult to Attach Liner with
    Non-Fish-Friendly Liner Gasket Weir Doors

    Typical Medium Pond Kits Difficult to install and non fish-friendly weir door



    Typical medium pond kits have a combination weir door and liner gasket flange. The gasket flange part attaches the pond liner to the pond skimmer. The weir door part enhances pond skimming. That is how it is done with typical medium pond kits ….. but should it be?


    First of all, let’s examine the first part: Liner gasket flange. 1. What is it? 2. What does it do? 3. Why is it needed?



    Simply questions. Here are the simple answers:

      1. A liner gasket flange is a piece of material that will hold pond liner to a pond skimmer
      2. It creates a “leak-free” of the pond liner and pond skimmer
      3. To attach pond liner to a pond skimmer


    Kind of a “no-brainer” …. or is it? 1. How do you attach it? 2. What could go wrong? 3. What would happen? ….. We’re glad you asked.

    Typical Medium Pond Kits Aluminum screw grommets corrode and leak
    Typical Medium Pond Kits Corroded and leaking aluminum grommet

      1. Typical medium pond kits with typical liner gasket flanges require a dozen screws or more and grommets to attach the liner gasket flange.
      2. As the pond ages and settles with ground movement from “freeze-thaw” cycles, monsoon seasons, and even earthquakes …. the liner will sag and stretch one or more of the dozen or so holes in the liner caused by the screws holding the conventional liner gasket flange in place.
      2a. If the screws holding the liner gasket flange are aluminum – as the case with most medium pond kits (a price reducing measure), the screws will corrode rather quickly and start to leak.
      3. A leak between the pond liner and pond skimmer will cause even more settling … which will cause even more leaking. Pond leaks cost lost of money in water replacement, and even more in leak correction.


    Ultimate Medium Pond Kits One nut liner attachment is more secure



    Quick and Easy Liner Attachment Pond liner attaches to the Piper HydroClean™ Professional Medium Pond Skimmer in all Ultimate Medium Pond Kits like all HydroClean™ pond skimmers … with a simple “One-Nut” liner collar.

    Unlike typical medium pond kits with pond skimmers that use a weir door face-plate with dozens of screws to secure pond liner to the skimmer, the Piper locks pond liner to itself, or remote installation pipe with a rubber collar and just one Stainless Steel nut on the Stainless Steel collar clamp.

    This drastically reduces the installation time, as well as frustration. The typical pond skimmer’s faceplate screws penetrate the pond liner in dozens of small holes that can eventually leak when they tear open due to liner settling over time. The HydroClean™ liner collar prevents these type of leaks.





    Typical Medium Pond Kits with Pond-Side Pond Skimmers Ruin the Look of the Pond

    Typical Medium Pond Kits Pond skimmer on the edge of the pond ruins the look of the pond


    No matter the manufacturer, or the brand: Aquascape, Atlantic, Pond Builder, Savio, Little Giant, Danner, Proline, American Pond … the list goes on and on …. their medium pond kits ALL require that you disrupt the look of your pond with a “pond-side” pond skimmer. It doesn’t matter is it’s a natural looking pond, or a formal, industrial, progressive, contemporary … or any other design type. A pond skimmer sitting on the edge of the pond ruins its appearance.

    The pond skimmer may have a faux-stone appearance – but it still doesn’t look good sitting on the edge of a pond. We’ve seen some pond owners who install a piece of stone slate over the pond skimmer to make it less unattractive. A piece of stone slate makes cleaning the pond skimmer more difficult. Stone slate large enough to cover a pond skimmer – and thick enough not to break when stood upon is very heavy. You don’t want to hurt yourself simply cleaning your pond skimmer.


    Ultimate Medium Pond Kits Remote installation capable pond skimmer


    Ultimate Medium Pond Kits with
    Piper HydroClean™ Pond Skimmers
    Make the Pond Look Better …. Take a Look


    No other brand of medium pond kits have pond skimmers that can attach to standard PVC or ABS piping for remote installation away from the pond edge.

    With the Piper HydroClean™ Professional Medium Pond Skimmer’s unique integrated round inlet pipe, you have the option to install your pond skimmer directly on your pond’s edge, or for the most natural looking pond edge – the Piper HydroClean™ Professional Pond Skimmer has the ability to be installed several feet away from the pond’s edge. The Piper HydroClean™ Professional Pond Skimmer’s integrated 6″ round inlet pipe attaches directly to PVC or ABS pipe for remote installation at any length you choose. No other medium pond kits have pond skimmers with these remote installation capabilities.

  • The patented Marlin Hydro Vortex™ Pond Filter included in Ultimate Medium Pond Kits is easy to clean and completely backflushable. Backflushing your waterfall filter keeps it performing at peak efficiency all year round which results in a much cleaner pond and a healthier ecosystem. This patented backwashable waterfall filter keeps you water garden clean and healthy.

    Backwashing the Marlin Hydro Vortex™ included with Ultimate MediumPond Kts




    The Marlin Hydro Vortex™ waterfall filter in Ultimate Medium Pond Kits combine high surface area bio media, a vortex solids separator, settling cone with a bottom drain for complete and efficient backwashing in the most advanced medium pond filter available. The Marlin Hydro Vortex™ waterfall filter does not require dismantling or air pumps for backwashing.

    Ultimate Medium Pond Kits come standard with an Marlin Hydro Vortex™ waterfall pond filter. This pond filter is designed for periodic gentle back-flushing of fish waste, mulm and detritus. Compare this to the massive disruptive heavy annual pressure washer cleaning  required by pond filters in typical medium pond kits. Don’t be misled by the claims from claims by manufacturers that say their biological filters only need “once-per-year-cleaning” – the beauty and cleanliness or your pond, as well as the health of your fish and pets may be at stake.  

    The HydroFlush™ option uses your existing pump and the included 3-way valve to reverse water flow through the filter. Cleaning an Marlin Hydro Vortex™ filter is as easy as opening its drain valve and turning the 3-way valve to HydroFlush™.

    All pond filters, no matter what type or brand, benefit from periodic rinsing of fish waste, mulm, and detritus.  Pond filters in typical medium pond kits are not designed with bottom clean-out drains for ease of cleaning and routine gentle back-flushing. 




    Typical Medium Pond Kits are NOT Backwashable – so this is what remains in the filter all year long!

    (Actual photos of an actual annual pond and filter cleaning – is this something YOU want to deal with every year?)

    Typical Medium Pond Kits Clogged media that feeds algae and fish disease
    Typical Medium Pond Kits soiled filter pads feed algae and fish disease

    The clogged media inside pond filters in typical medium pond kits waiting for their annual cleaning can cause poor water quality and can encourage algae growth and fish disease in the mean time.

    allow you to easily rinse the bio media without harming the biofilm
    Keeping Your Pond Clean, Beautiful, Fresh, and Healthy ALL YEAR ROUND!
