AlphaONE Filters utilize the AquaSwirl internal Vortex spinning design that spins heavier solids to the center of the bottom of the vessel. AlphaONE filters also feature the AlphaONE Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during times of medical shutdowns, pumps failures, etc. The 2" Clear Union Spring Check Valve located right under the blower provides maximum flow and has built-in unions. If you should ever have to replace the spring check valve, it is no big deal. Just unscrew the top and bottom of the valve, remove the valve body, replace with a new body and re-hand tighten the two unions. Total repair time is under 2 minutes!

AlphaONE LH Filters from GCTek deliver the same world-class performance as standard AlphaONE Filters with less head. This allows you to achieve the same stellar results while using a much smaller pump, resulting in a significant energy savings! All of the AlphaONE filters utilize the AquaSwirl internal Vortex spinning design that spins heavier solids to the center of the bottom of the vessel.

The AlphaONE Bead Agitator is a dynamo powerhouse of air output. What does it do? During normal running of the filter the beneficial bacteria causes the beads to be sticky (that's good). In the normal running of the filter algae and other solids combine with the sticky beads to try and form a "glue" that glues the beads together. At the same time the algae and other solids combine and grow larger as time goes by. To properly get them out of the filter when it is backwashed, we need to break this bead "pac" apart and pulverize the solids to a small size again so we can backwash them out of the filter. That's the job of the AlphaONE Bead Agitator. When you kick this 1 horsepower powerhouse into action, humongous amounts of air are injected at the bottom of the filter where the air then rises and as it does "breaks apart the bead pac", thus allowing for a good back wash to be engaged at this point. What goes on inside is a violent rushing of air into the vessel breaking apart the bead pack, but not so hard as to disrupt the beneficial bacteria growing on the beads. The AlphaONE filters were designed to be the most energy efficient filters on the market. Inside is more than double the lateral surface area, where the upper beads gather around the slots in the lateral arms, than that used on any other filter. Couple this with the highest flow multiport valve on the market and you have a filter that was designed to be energy efficient. By implementing these design characteristics the filter can save the end user hundreds of dollars a year in energy costs. A smaller more energy efficient pump can be used to handle ponds that would normally have to have larger energy "hog" pumps to turn the pond over at the suggested rates. Why do we care, we're not paying the electric bill? We are committed to doing our part to conserve our natural resources. In our operation we recycle everything we can to hold down costs and do our part for the environment. AlphaONE filters also come with a special wrench that fits over the top cap and allows you to unscrew the cap and gain access. Did you notice I did not say to "unhook your plumbing"? With some bead filters who use top mount valves it is necessary to unhook the plumbing to get inside. Not fun. GCTek, makers of the AlphaONE Filters, knew you wouldn't like this, so they didn't use a top mount design. Unlike lesser quality filters made of plastic, AlphaONE filters is made of fiberglass. This costs a bit more than plastic, but it is also of better quality. GCTek only wanted to use the best and the fiberglass is rated at 50 psi. AlphaONE Filters are also sensibly priced when compared to similar filters on the market.

AquaBead LH Filtersprovide the same world-class performance as standard AquaBead Filters but with less head pressure, allowing you to achieve the same flow rates with a much smaller pump -- resulting in huge energy savings! With electrical rates on the rise through out the world it is only smart to think in this direction. The use of a smaller pump can save you hundreds of dollars a year. The AquaBead LH has all the features of the AquaBead filter with the extra added benefits of the LH series. The AquaBead LH Filter is just the latest innovation from GCTek, one of the most respected and industry leaders in Koi pond filtration. With years of thought and testing we are proud to release the filter that already has people talking. The multiport valve on AquaBead LH Filters is far less restrictive than those found on competitive filters on the market today. You bypass the multiport when you are in the regular filtration mode. Water only goes through the multiport valve when backwashing. Simply move 2 push-pull type valves and the water flows through the multiport valve to allow for backwashing, rinse, etc. Then move the push-pull valves back to their original position and water flows through the filter as normal but unrestricted. Water enters the lower port and exits the upper port going back to the pond. Why is all of this important? It allows you to run a smaller more energy efficient pump to do the same job. This is good for the environment and your pocket book. The AquaBead LH Filter is available in a wide variety of sizes for every pond. If you are looking for a filter that has the lowest restriction of any filter made, this is it. You can use the most energy efficient pump on this filter and receive maximum flows with very little head pressure. This saves you at the electric meter and in the wallet. Truly an EcoFriendly filter for our modern day ponds.

This exciting new UV was designed to work with today's low amperage pumps and high flow filters, such as the AlphaONE. Sporting an impressive 4" vessel with 2" inlets/outlets means no flow restrictions. These units are truly high performance/high intensity units utilizing over 70,000 microwatts of killing power. Few UV's can make this claim. These units won't nickel and dime you to death. Replace only one lamp instead of several. This could save you big money! Changing a lamp or ballast on these is so simple even an adult can do it. It's not as complicated as programming your VCR. Remove the top cover, unplug the single 4 prong connector, slide out the lamp and insert the new one and you're done. Removing the quartz tube is just as easy.

GCTek BioSheild UV Sterilzers feature 6" housings with 3" inlet/outlet with bushings for connection to 2" PVC.

The PondKeeper filter utilizes a totally unique backwashing jetting system GC Tec calls the "FLUFF-N-SPIN" system. Not only does the internal design of the filter allow for a "FLUFFING"; of the media during backwash, but spins the bed and each individual piece of the PondKeeper media. This causes the media to get rid of any old bio floc that might be clinging to each piece, while holding on to the precious beneficial bacteria within the filter. There is no other like it. Due to " FLUFF-N-SPIN" agitation system and the design of the media, these units backwash beautifully using any low aperage Koi pond pumps.
