Why should water be softened?

  1. Hard water tends to cause limescale. Limescale deposits in pipelines lead to fouling and biofilms.
  2. Limescale deposits can reduce the lifespan of the heater.
  3. Hard water leads to rapidly increasing pH values that can only be lowered with a lot of pH-minus. Constantly lowering the pH value is time-consuming and expensive.
  4. Hard water with a high pH value can lead to cloudiness in the water.
  5. Hard water reduces the effectiveness of water care products. 

IMPORTANT!

Do I need additional equipment?

Yes, we recommend purchasing an "aquarium submersible pump" with a flow rate of 500L to a maximum of 1500L per hour. Ideally, use the following pump with a 600L flow rate per hour: Click here

 

What do I need the aquarium pump for?

The granules in the Calc Down Pads must be flowed through with water. When the granules absorb water, the flow is significantly disrupted. With the aquarium pump, we force the water through the granules. Without the aquarium pump, the Calc Down Pad cannot function properly.

How do Calc Down Pads work?

Calc Down Pads contain special granules that are charged with sodium ions. In water, the granules release sodium ions and absorb calcium ions, thereby softening the water.

How do I determine water hardness?

Ask your water supplier. They know your water hardness. Ask for the total hardness in German degrees of hardness. Alternatively, you can determine the water hardness yourself with our Water Hardness Test Kit.

What is the ideal water hardness in a hot tub?

The ideal water hardness is between 7 and 10 German degrees of hardness. Do not lower the water hardness below 7 °dH. Water that is too soft can quickly become corrosive and the pH value will not remain stable.

How long does water softening take?

The duration depends on the water hardness and the number of required cycles.

Application

Pad placement

Good flow through the pad is important for quick and effective water softening. Cut the conical end with scissors to the diameter of the pump nozzle. Insert the pump nozzle into the cut end of the Calc Down Pad and secure the pump nozzle with the enclosed hose clamp.
Submerge the pad in the hot tub and switch on the aquarium pump.

Important: Do not use the hot tub while the aquarium pump is switched on.

Reducing water hardness

To reduce 1000 liters of water by 7 °dH, you need one cycle (approx. 1 day). After that, the pad must be regenerated. Regeneration also takes approx. 1 day. In the diagrams, you can see how many cycles you need. If your hot tub size is not included, take the first diagram and multiply it by the respective factor. For 1200 liters, this would be 1.2, for a capacity of 2000 liters, it would be 2.0. These are approximate figures that may vary on-site. With the total hardness test kit, you can measure the exact amount of one cycle at your location.

Note:
You cannot measure when the pad is charged or discharged. You can only measure whether it still reduces water hardness. Use our total hardness test kit for this.

How do I regenerate the Calc Down Pad?

Remove the pad from the hot tub and place it unchanged, connected to the aquarium pump, in a sufficiently large container with approx. 25% salinity. This corresponds to approximately 360 grams per liter at room temperature. Use dishwasher salt for this, as other salts have an anti-caking agent added. Switch on the aquarium pump and leave the pad in the saline solution for approx. 24 hours.

How is the Calc Down Pad stored?

The pad must not dry out, otherwise the granules will crack and become unusable. Place the moist pad in the original bag and seal it.

How often can I use the Calc Down Pad?

We recommend using the pad a maximum of five to six times. The seams are not designed for continuous operation and may tear with prolonged use.
