This 1 1/4 inch by 6 inch core SpaCore Natural Water Filter provides excellent, chlorine-free water for natural spas and hot tubs. Place inside your sediment filter – no plumbing involved to install. Takes out the chlorine that irritates eyes, nose, and lungs, skin, hair – and bathing suits!
Copper-zinc media maintains a bacteriostatic environment in the filter and removes heavy metals and inorganics. Releases low-level healthy trace elements copper and zinc ions into the water to prevent algae and fungus growth. Controls scale, renders chemicals inert. Place the SpaCore inside your sediment filter. For spas and hot tubs up to 400 gallons – lasts 4 or 5 months. If the water gets cloudy sooner, it’s time to replace the filter.
All the water does not need to touch the disk. The filter material works by releasing trace elements into the water.

If as a result of heavy usage or rainfall, you can mini-shock your spa with chlorine or a non-organic shocking agent. Take the filter out for 12 hours, then then insert to clear the water again.
