SkagiTek True Pre-Filter
The True Pre-filter is available in two sizes to handle the job. Install in front of a pump to maximize on trapping debris and reducing maintenance on other filters while protecting the pump. The True Pre-filter is a study canister with a heavy-duty extra large capacity Stainless Steel basket inside. With this Pre-filter, you are going to be pleasantly surprised at just how much it can hold and the quality of the units. In the True Pre-filter, the water enters from above the basket enabling even more capacity over conventional designs that has the water enter from the side. Keep your flow rates up and your filters clogging less with a True Pre-filter.
Food for thought, if a 3 inch pipe holds 4 times the volume of a 2 inch pipe, then wonder just how much a 7.5 inch inside diameter Stainless Steel basket can hold over the other plastic baskets on the market that have 4.5 inches at the top with a 3 inch wide bottom.
Benefits
-
Trap a Surprising Amount of Debris
The True Pre-filter Stainless Steel basket holes are 5/64 inch small and round in shape as compared to the plastic baskets of other brands which are at least a square 1/8 inch or larger, thus permitting larger debris through and forcing you to backwash your filters more often. Many of the other baskets are closer to 1/4″ x 3/8″ openings which do permit small rocks that damage the pumps internal parts.
-
An Industrial Grade Basket
The solid stainless steel basket with its sturdy handle is sure to impress any professional or serious customer setting up their pond equipment. Many have called back after installing the True Pre-filter, very excited about the quality and sturdiness. The need for this design came about from a great number of customers needing to replace their broken plastic baskets, which get weaker and crack after a short time.
-
A Level of Quality You Can Trust
The gray body is a sturdy and thick-like schedule 80 PVC material for a very strong canister. The canister has a sealed clear dome lid making this a pressurized system benefiting the priming of pumps because of its capacity to hold water even if your pump is not a self priming pump. The 2 inch unions are custom made and very strong. With a union on each port, it makes for ease of removal for those in colder climates that prefer to bring in equipment during the harsh winters. A small ball valve is located on the lower side for draining if needed. A cap is installed over it to protect the threads that also permit attaching a garden hose. The clear dome lid makes it easy to see when to service.

SkagiTek True Filters
SkagiTek True Glass Bead Filter
The True Glass Bead Filter has a unique design that safely polishes the water by trapping fines and solids down to 3 micron, thus outperforming bead filters or other brands of glass filters. This results in clearing your pond of crud floating through the water and polish it to look like mountain spring water. The only thing you’ll see is the fish!
Unlike other glass filters that use unsafe crushed glass, our glass bead filters use hardened and truly round glass beads that are very safe to handle. So safe, we added over ten pounds of them into our Koi pond. They were in there for 9 months and have had no issues with the Koi or plugging the drains.
Benefits
-
Superior Clarity
The next generation of refining water quality is here. The True Glass Bead filter polishes water so well, you may just see some aqua color return to your water similar to the day you first filled the pond. It can remove suspended debris down to 3 micron leaving only the water and the fish to enjoy.
-
Unique True Glass Beads
The True Glass Bead Filter has a proven fish-safe media that is specifically designed to polish water. Because the polished beads have a hardness of #7 which is the same as a Carbon kitchen knife, it is very hard for beneficial bacterium to grow on. This benefits the design by not getting gummed up like crushed glass does and requiring the use of a hazardous chemical known as Potassium Permaganate to clean the media like other glass filters.
-
Designed with Versatility in Mind
The True Glass Bead Filters offer a diverse means of installation unlike any other brand. You can choose to setup your filter either as a stand-alone polishing filter with a dedicated low amp, low rpm pump (recommended) or in series after another pressurized bead filter to polish what the standard bead filter did not (not-recommended – series installs will require a high amp, high rpm pump).
SkagiTek True BiO Filter
The True BiO filter’s proven design is unlike regular biological combination filters that trap solids. The True BiO Filters feature media that have a unique combination of Vast Surface Area and Open-Flow Porosity that make it the most unique and highest capacity bio-filter media available today. The ceramic composition is comparable to natural rock, but with incredible surface area of approximately 150,000 sq ft per cubic foot. The properties of the True BiO’s media create a stable home for beneficial bacteria that remove ammonia and nitrites. Some systems will also see a decrease in Nitrates. The combination and overall design provides an optimum bio technology environment for growing a more aggressive species of beneficial bacterium. Also, this media’s open porosity resists clogging and reduces pond maintenance.
For comparison, some $3,000 bead filters have less than 4000 sq. ft. of surface area and even then, it is only a claim, it is not backed by testing like the media we use that was tested by a University. Take Advantage of True Bio filtration and install after a bead filter or other mechanical filter.
Benefits
-
New Innovative Design
The in-line design is easy to install with 2 inch disconnect unions on each port. To connect, simply install after the pre-filter that removes or traps debris (Bead filters perform this very well). The sturdy components are all well designed and strong. Each True BiO filter is a pressurized canister permitting installation with endless possibilities.
-
Introducing a Revolutionary Media
The orientation of media in the chambers of these filters create fast pathways and slow pathways for the water to move through. The combination of the ceramic with the fast and slow pathways inside the bio-filter is known to grow the most comprehensive range of bacteria for nitrogen cycle conversion. This makes it possible for nitrosomonas, nitrobacters and facultative bacteria to exist and give you the most complete nitrogen cycle possible in a biological filtration system.

Easy to connect
Say goodbye to figuring out how to plumb a filter. This filter easily connects using hose bib connections. Simply connect your supply hose to the entry bib connection and its ready to start supplying fresh clean and safe water out the upper hose bib connection. The upper bib connection has a ball valve that permits complete control of the flow.

Long Lasting, Quality Carbon
Our pellet carbon has the capacity to keep on absorbing. It not only retains Superior abortion capabilities, it also converts the toxic Chlorine catalytically so you get fresh Chlorine free water for years. Pellet carbon also assures high flow capabilities and no clogging.
The amount of carbon assures a very generous amount of surface area to continue handling both physical and chemical process to filter out unwanted contaminants. The physical process involves running water through a media that retains the contaminants while allowing the water to pass. The chemical process uses a reaction called adsorption, in which the atomic charge of the carbon and other media causes the contaminants to abandon their bond with the water and chemically attach to the media.
The True Purifier was designed to provide a continuous supply of water and treat it for for years with no maintenance required.
-
Plenty of Features Every Pond Needs
The water enters the base and is permitted to be used from two points. One point is lower and unfiltered while the upper point is 100% filtered. Both connections are hose bib male threaded ball valves that permit the connection of a garden hose to each. Use the lower point as a handy location for any number of reasons you may find the need to have a hose connection for.
The water that reaches the upper hose bib point passes through a per-filter, the carbon and then a fines filter resulting in treated fresh filtered water.
The filter pads inside are washable and easy to replace. The Carbon is self contained in a bag for easy lift out replacement. It can easily last for 5 years of continuous water passing through it when just used as a carbon filter to remove Chlorine. To replace, open the top, lift out the bag, empty and refill with new carbon.
