SPA-CORE
SPA & HOT TUB NON-CHEMICAL WATER TREATMENT
Installs in sediment filter in seconds.
Easy Installation:
1. Put the Spa•Core into the hollow core of clean sediment filter.
2. Make sure Spa•Core fits snugly. If necessary, use the Spaguard and enclosed cloth bag around the Spa•Core to make sure the disk does not get sucked into the return.
3. Make sure Spa•Core is at the bottom of the sediment filter when placed in the spa (see illustration).
4. You’re done. Enjoy clean non-chemical bathing!
The Filter Foam technology uses Power Disks to provide excellent, chlorine-free water for swimming pools and spas through filtration rather than the introduction of chemicals to the water. Chlorine attacks organic matter, and your skin is your body's largest organ. Chlorine irritates eyes, nose membranes, and lungs and it leaves skin and hair dry and flaky. Studies have shown that long-term exposure to chlorine can be harmful to your health. Polymeric Biguanide products to chlorine can also cause allergic reactions and can permeate the pool or spa walls.
Filter Foam Disks use a unique form of KDF copper-zinc media which has been molded, via a proprietary process, into a soft disk that looks like a gold sponge. KDF is excellent at removing chlorine for long periods of time while also acting as a descalant and maintaining a bacteriostatic environment. KDF meets NSF Standards 42 and 61 and has been tested to remove heavy metals and inorganics as well as chlorine from water.
Filtration inside the pool or spa system takes place as the water twists and turns through the Power Disks' maze of copper-zinc fibers. This tortuous movement increases contact time with the disks during each pass through the media, as the water is recirculated through the media over and over.
Filter Foam Power Disks use an all-natural process that works by catalytic action and the redox (reduction/oxidation) principal of dissimilar metals. As water passes through the Power Disks, a chemical reaction causes zinc and copper hydroxides to form in controlled amounts. These controlled releases of copper and zinc oxides are carried into the filtered water where they provide hostile conditions for growth. This means cleaner water for bathing, plus reduced time and labor in keeping the pool or spa clean.
Filter Foam Disks also safeguard your pool and spa by reducing the need for chlorine and other chemicals that corrode pipes and equipment. Plus, chemical costs are minimal. After heavy loads from excess bathers, heavy rain, wind or pets, a one-time shock treatment, with potassium monopersulfate, or other shocking agents like ozone, hydrogen peroxide, or chlorine, is usually sufficient to solve the problem. The Power Disks also help to neutralize slightly acidic water, thereby reducing or eliminating the use of pH chemicals.
USING THE POOL-DISK AND THE SPA-DISK
Water flowing through the DISK is what makes it work. A pool or spa needs to circulate
the water to provide maximum contact with the disk. The best way to do this is to
circulate the water for at least 12 continuous hours each day at 10 gpm in spas or
the normal flow rate for pools 24 hours 7 days a week. Do not allow suctioning except
at the skimmer or wherever the disk is placed. If 12 continuous hours is not possible,
use the pump to circulate the water for two, 2-hour periods daily AND run the pump
at low speed for at least 30 minutes after each spa use.
Don't worry about pH with the disks. They regulate themselves usually between 7.6
and 8 and occasionally from 7.4 to 8.2. Chemicals intended to control pH severely
reduce the disk's efficiency. Most pH parameters for pools and spas are based on
using chlorine and are not relevant when the disk is used.
Likewise, the disks tend to regulate water's softness. The main reason water is
hard is that calcium is present. The DISKs do not remove calcium, but they make the
water act softer by changing calcium's cellular morphology so that it cannot adhere
to a surface. The calcium does not deposit scale on surfaces.
If you test the water for softness in a DISK treated pool or spa, however, the test will show any calcium present because it does not distinguish between calcium's various morphologies.
There are no health issues with the disk's capacity to make water act softer. Using chemicals to soften the water, in addition to the disk, will restrict the efficiency and life of the disk. In normal operating conditions using the disk, no chemicals are needed for softening.
The POOL DISK comes with a black disk guard designed to capture sediment. If the
guard becomes clogged, it decreases the flow of water through the disk. Keep the
guard clean by peeling it from the disk, washing it in water and replacing on the
top of the disk.
The SPA DISK does not have a disk guard because spas usually have sediment filters
to remove debris, soap or oil. Check your SPA DISK periodically to make sure it is
not clogged as this would reduce the flow of water through the disk. If you notice
debris or material on the disk, remove the disk, clean it with water and replace
it.
