FILTER RATINGS: Use this chart as you consider each filter type.

Note: Our filter ratings indicate suitability based on performance and take into account the following considerations:

CLEANING: frequency, ease, efficiency, etc.

SIZE: actual size, installed size, hide-ability, etc.

LIFE EXPECTANCY: expected life of filter itself, availability of parts, redundancy, durability, etc.

COST: initial cost, parts maintenance, cost of replacement parts, etc.

It may be necessary to build your first pond with less than the best filter. Generally the cost of high performance filters increases as the performance level increases. Note that cost may become less of an issue if the filter makes your pond a real enjoyment over a 15-30 year period. For such a long period, it will become the least important consideration when compared to such things as efforts required to keep the pond clean. Also note that all of the above filters perform best in conjunction with installation of the recommended UV sterilizer.

Best Filter Ever!  

AquadyneTM

The Worlds First Perfect Bead Filtration Systems

Loaded with ALL POSSIBLE FEATURES

Power Backwash Bottom Sludge Drain 5 Minute Disassembly Micro Sediment Removal No Flow Restrictions Full 6" Tank Opening Dry Hands Cleaning Efficient Up-Flow Bead type

Complete Medical Bypass Full Rinse Cycle Full Media Access Advanced Backwashing Internal Sedimentation One Touch Operation 5 Minute Weekly Cleaning Optional Dyna-Max Blower

New engineering technology through a newly developed, highly specialized central diffuser column virtually eliminates internal friction loss and clogging problems associated with other bead systems on the market. Add in the fact that this filter is designed from the beginning to operate with energy efficient low head Superfalls pumps, and you have the best filter available! Even the pro's say it's too good to be true, but this is one product that is compact and truly performs, without having to install a filter as big as your car next to your pond. And best of all, you never get your hands wet while cleaning.

"It is a fact that bead filtration is the most effective and practical filtration ever developed. There is no other filtration technology, in such a small package, that minimizes the retention of organics in a living aquatic eco-system; significantly UN-like outmoded (and downright hazardous) "brush and pad filters" which are known to encourage the proliferation of pathogenic Pseudo-monads and fungi such a Branchiomyces. Since the first system I tested, I have always known that I would never demote myself from bead technology, as even the first designs were very effective. But most notably, with the advent of "flick of the wrist" power backwashing, and even newer developments in the Aquadyne series. The Aquadyne design has no internal elbows, and allows maximum water flow under the most abusive feeding practices. Aquadyne supports colossal amounts of fish AND delivers GIN CLEAR water, with no flow restrictions. I cannot foresee a more perfect bead filter being introduced. The best part of this filter is it's unique plumbing which allows water to bypass the filter completely, for medication purposes. The rinse cycle is an absolute must, as there is absolutely no "brown dirt cloud" after a backwash" as in the bubble bead filters. In a nutshell, Aquadyne is the Pentium of bead filters. - - - - Dr. Erik Johnson, DVM

Recommended Use: Install one or more or our Giant Leaf Traps with lid (cost $299.99 to399.99) in ground next to pond and plumb to pond drain. Plumb pump suction to Giant Leaf Trap to collect and contain pond waste material for later removal. This minimizes filter and pond cleaning, and maximizes filter operational times. Recommend ordering at least one extra basket and filter mat for ease of cleaning.

Chart, Data Clarification:

The Maximum Pond Size shown indicates the maximum pond size for greatest biological efficiency of a given system. Pond size can also be significantly smaller than the maximum rating. By using a larger system on a smaller pond, you will only further increase the biological cleanliness of the pond environment. Likewise, the pond could also be slightly larger than the rating on a system provided that there was not a significant fish load. (See Fish Capacity Data Above)

The Minimum Flow Rates indicated in the chart indicate the minimum flow rates required to backwash. Flow rates during the normal filter cycle can be significantly slower than indicated in the chart. However, during the backwash cycle, you must have the ability to increase the flow to the minimum rating for a proper backwash, or use the blower to achieve maximum backwash with least water loss. The maximum flow rates listed are a cross section of two factors. Mechanical control head port size for efficient flow without significant restriction, and contaminated water contact exposure to the billions of beneficial bacteria residing within the filter. Without a doubt, slower flow during the filter cycle is better, but, a faster flow rate also places the recirculating water in contact with the media more frequently, netting near identical nitrification results.

The Maximum Pressure Rating all Aquadyne systems is a whopping 50 psi ! --- We actually consider this a non issue, because the Central Diffuser column on our filter is so efficient and non-restrictive that you would have to install a 5HP pump and have the filter half clogged to put anywhere near 50 psi on the tank. This simply would not occur in any practical application so we consider it just a perk.

On The Other Hand, you should be aware that due to the spin welding that some competitors must use to attach fittings to their tanks, and thin tank wall construction, they can only rate their tank pressures at 15PSI Max. Hardly sufficient for medium head pumps capable of any decent flow rate.

New! POND SWEEP SKIMMERS , FILTERS AND ACCESSORIES

PondSweep® Skimmer

One important advantage of the PondSweep® skimmer over other brands of skimmers such as the Aquascapes® skimmers, is that they can be used with bottom drains while others cannot.

A cutaway view of a PondSweep® skimmer showing its fish-safe design with a full net with rigid frame and a mat and mat holder preventing fish or large debris from reaching the pump shown on the right. The optional drain inlet on the right allows top and bottom pond circulation using only one pump.

Applying caulk between the liner and the skimmer.

Attaching the retention frame to the PondSweep® skimmer box is easy and assures a leak-free seal to the pond liner.

John Menhart, P.E. is holding the skimmer net. The owner's ryukin goldfish is a slow swimmer, but he was never harmed when caught in this skimmer, because of its patented, fish-safe design. After two weeks and quite a few visits into the net, the ryukin learned to keep a safe distance from the PondSweep skimmer in the pond.

The PSM skimmer box is available with an optional fiberglass lid that looks like flagstone (shown in first picture above). If you choose, however, you can cover your skimmer with actual rock to make it match the rest of your pond better.

Contents standard with all models:

one filter mat, mat holder, debris net, retention frame, bellows weir and tab, silicone sealant, attachment hardware, written and video installation instructions.

PuriFalls® Filters

Leveling the PuriFalls® side to side is important to achieve a uniform flow from your waterfall.

The waterfall lip overlaps the liner by 5 inches, making it very easy to achieve a leak free waterfall. This is a great design feature of these combination waterfall and filter units.

We recommend a waterfall stone sealant like foam polyurethane to seal the waterfall to the water fall stone to the top lip of the PuriFalls®.

BECKETT FILTERS

You need the extra filtration of a Beckett out-of-the-water filter. One reason is capacity-larger ponds need larger filters. The number of plants and fish in your pond also affect the size of your filter. You may also choose a larger filter to help make your pond maintenance easier. Beckett out-of-the-water pond filters increase the level of the oxygen that good bacteria, or nutrifiers , need to live. More oxygen means more nutrifiers, which means better filtration. Beckett filters come in three styles: mechanical filter with planter top, medium box filter and large box filter.

DRUM/STRAINER-LEAF TRAP

 
Koi Joy's collection trap connects' directly to the pond's bottom drain line (3" or 4") and skimmer to collect debris from pond. Water travels upward into the strainer basket, and then through the basket into the collection tank where it is drawn into the pump. The pump is connected via a 2" bulk head fitting (supplied). Debris is left behind within the strainer for easy removal and cleaning. Saves a lot of effort and time that would be spent cleaning your pond, leaf trap, or pump internals. Available for 3" pipe 04-LCT300 or 4" pipe 04-LCT400 Supplied with lid (not shown), strainer basket 04-LCB300 or 04-LCB400, leaf basket filter media 04-LBFM25, and 2" bulk head fitting 03-BHF200.
With this system, you can now clean your pond by sweeping stuff directly into the bottom drain to be swept into the collection trap. This easy to clean trap will hold weeks of bottom debris for later removal.

Now you won't have to worry about leaves plugging up your pump or your skimmer.  When it fills with leaves or algae, simply pull it out, rinse out with garden hose and return to drum. It's simple slip fit makes removal and replacement easy and painless. Plumb your centrifugal pump directly to the drum with one of our bulk head fittings (not included) for strained water or simply place a submersible pump into the drum with its hose leading to your filter. A simple yet effective way to decrease your pond maintenance duties and protect your koi!

INLET STRAINER

 The Inlet Strainer is constructed of 2'' Perforated pipe ( for minimal restriction) a Tee and 2 caps. Available with a check valve for pumps that are not self priming. Approximately 3 1/2 feet across to allow a large surface area which cannot easily clog or become obstructed. Perfect for a pond that was not originally built with a bottom drain when adding a centrifugal pump. Install at the bottom of the pond, over the side, or by penetrating the liner with an elbow and appropriate length pipe.  

BIO-FILTER ROLL/PAD MEDIAS

Our 1 " roll media works well in the DRUM filter 04-UF1000 or any other bio-filter of your own construction. Use a 55 gallon plastic drum such as our 04-PD0055 or one of your own. One roll of this material will treat up to 1000 gallons. Roll comes 25 ft long by 25 inches wide or in two rolls 25 ft long by 12 1/2 inches wide each. Long lasting and easy to wash, this makes an easily constructed bio-filter for a small pond or a large tank.
 
   

NEW! MEGALITE COMPACT BIO-MEDIA

Because this new filter media has the most useable surface area of any bio-filter media, it is the best material for use in bio-filter beds. It is approximately 1/4 the weight of pea gravel (32 lbs/ft3) which makes it easy to handle and has many times more surface area for bacteria to colonize. One cubic ft of MEGALITE has 16 acres (700,000 ft²) of usable surface area within it's millions of pores. The exciting thing about MEGALITE is that nearly all of the pores are greater than 1 micron in diameter allowing bacteria to colonize and live (many gravels have large areas comprised of pores too small for bacteria to survive). With this large area for bacteria to grow on, the size of your bio-filter can be reduced and still perform as well as a filter many times as large. Use this material in your filters to increase their bio-filtering capacity. Available in 18 lb bags or 70 lb. "buckets" for large filters (with our slotted pipe below, this makes the perfect material for an in-pond gravel filter). MEGALITE is available in 2mm diameter (1/12 inch) and 4mm diameter (approx 1/6") for sand type filters, and 6mm diameter (approximately 1/4"). Available only from Koi Joy! For more information, go to specs.html.
 

BALANCE KILN FIRED BIO-MEDIA

This filter media is a perfect material for use as a replacement for gravel or rock. It is approximately 1/2 the weight of gravel and has many times more surface area for bacteria to colonize. One cubic ft of Balance has 3 acres (140,000 ft²) of usable surface area. With this large area for bacteria to grow on, the size of your bio-filter can be reduced and still perform as well as a filter 2-3 times as large. Use this material in your filters to increase their bio-filtering capacity. Available in 25 lb bags or 1000 lb. "super sacks" for large filters (with our slotted pipe below, this makes the perfect material for an in-pond gravel filter).
 
 

BIO-LYTE GRAVEL ZEO-LITE/FILTER MEDIA: NOWHERE ELSE!

Our natural zeo-lite gravels have three unique properties. Because of its large void space, our gravel has a tremendous surface area. Some of this large surface area is within the pores and voids, while the rest is on the exterior surface. These two regions of high surface area combine to make one of the most compact media available for filters.

It's added ability to remove ammonia directly from pond water as it's generated, prevents the ammonia cycle swings common to most ponds and bio-filters. The ammonia resulting from fish waste and other sources are the major contributing factor to pond fish disease and death. One ft3 of BIO-LYTE GRAVEL can remove more than 1 lb of ammonia before regeneration is necessary. When its ion exchange capability is depleted, BIO-LYTE GRAVEL is still working better as a bio filter media than most others! When depleted, or on a monthly or quarterly basis, simply valve out your filter, turn off pump, and add a solution of salt water. The salt water forces all of the accumulated ammonia out of the BIO-LYTE GRAVEL which is then discharged to drain. Backwash and rinse out filter, and then return to service (we recommend installing an air backwash manifold under the gravel or use of a garden hose & water jet to simplify backwashing). Important: BIO-LYTE concentrates ammonia and therefore prior to recharging, remove from pond or isolate filter from pond to assure fish are not exposed to this higher level of ammonia. Never add salt to pond containing BIO-LYTE or zeo-lyte.

BIO-LYTE GRAVEL has a weight of 60 lb/ft3, 50 % of the weight of pea gravel, making it light enough to handle easily. This light weight makes it easier to handle, backwash, and use in almost any container-even plastic drums, Rubbermaid stock tanks, or our square 45 gal SLT-45 filter tubs. Try that with pea gravel or rock! We truly believe our BIO-LYTE GRAVEL to be the revolution in pond filters we've all been waiting for. Use it in your next filter to reduce it's size or replace the gravel in your existing filter to increase it's performance (up to double the performance of pea gravel).

Use 04-BL0010, 10 lb  hanging bags of BIO-LYTE GRAVEL to hang in pond or tank, or toss into filter to improve its performance. Use one or more bags for each 1000-2000 gallons in pond, or one for each sick tank, show  or display tank. Each bag can absorb more than 1/3 lb ammonia from your water. BIO-LYTE GRAVEL polyester weave bags have brass grommets and drawstrings with barrel locks. Remove periodically and recharge with salt as above (frequency depends on number of bags, how well your filter works, quantity of fish, etc.). These are the only way of absorbing ammonia in cold winter pond water after your bio-filter's bacteria has died off. Protect your valuable koi during the winter month's too!
 

SPRING FLO PLASTIC BIO-FILTER MEDIA

One spool of this ribbon contains a massive 180 ft2 (16.5 square meters) of surface area for bacteria to colonize and may fill from 1 1/2 to 3 ft3 of space. One spool of Spring Flo is capable of nitrifying approximately 1/2 pound of dry fish food per day- equal to a pond with 25 pounds of fish! Sold in the form of a spool of ribbon, you simply let the material unwind freely into your filter box, drum, etc. until the container is full. One 55 gallon drum will hold two of these rolls to handle a 2,000 gallon pond.

To clean, just pick it up and shake or stir. Then drain your filter to discharge the dirt to waste. Made in England.
