Why should the water be softened?

1. Hard water is prone to lime precipitation. Lime deposits in the pipes lead to deposits and biofilms.
2. Lime deposits can reduce the service life of the heating.
3. Hard water leads to strongly increasing pH values which can only be lowered with a lot of pH minus. The constant lowering of the pH-value costs a lot of time and is expensive.
4. Hard water with a high pH value can lead to clouding of the water.
5. Hard water reduces the effectiveness of water care products.

How do I determine the hardness of the water?

Ask your water supplier about the hardness of your water. Let them give you the total hardness in degrees of english hardness.
You can determine the water hardness yourself with our Water Hardness Test Set.

How do I measure the water hardness?

Fill the measuring cup with 5 ml water from the whirlpool. Now add the measuring liquid drop by drop. Shake the liquid after each drop so that the water and the measuring liquid mix. The water turns red. Count the drops you add. As soon as the water turns green, you have determined the degree of hardness. Each drop corresponds to 1 degree of German hardness. If the water in the measuring cup changes colour from red to green with 10 drops, you have a water hardness of 10 degrees German hardness.

What is the ideal water hardness in a whirlpool?

The ideal water hardness is between 7 and 10 degrees of German hardness.

How many Soft Water Pads do I need?

This depends on the water hardness and the water content. Use this table as a guide.The information relates to 1,000 liters.

Initial hardness: 15  20 25  30  35  40  45  50  55 
Target hardness                  
 5  1,1 kg 1,7 kg  2,3 kg   2,9 kg  3,4 kg  4,0 kg  4,6 kg  5,1 kg  5,7 kg
 7  0,9 kg  1,5 kg  2,1 kg   2,6 kg  3,2 kg  3,8 kg 4,4 kg  4,9 kg  5,5 kg 
10  0,6 kg 0,9 kg  1,5 kg  2,1 kg  2,6 kg  3,2 kg  3,8 kg  4,3 kg  4,9 kg 
12   0,3 kg 0,9 kg 
1,5 kg  2,1 kg  2,6 kg  3,2 kg  3,8 kg  4,3 kg  4,9 kg 
15   0,0 kg 0,6 kg  1,1 kg  1,7 kg  2,3 kg  2,9 kg  3,4 kg  4,0 kg  4,6 kg 

A Soft Water Pad has a weight of 0.8 kg.


You have a water hardness of 30 and want to reduce the water hardness to 12. Your whirlpool has a water volume of 1200 litres.
You then take 2.1 kg and multiply it by 1.2(1200 litres). Result: 2.52 kg. You divide the 2.52 kg by 0.8 kg(weight of the Soft Water Pad) The result is 3.15. In this case you need 3 Soft Water Pads as one pad contains 0.8 kg softener mineral.
You can also take 2 Soft Water Pads and soak the Soft Water Pads(when the water hardness no longer decreases) for a few days in distilled water with 30% salt content. This removes the calcium ions from the softener mineral and replaces them with sodium ions. The Pads can then be reused.

Where should the Soft Water Pads be placed?

A good flow is important for a fast and effective softening of the water with the Soft Water Pads. It is best to place them in the filter chamber. For whirlpools without a filter chamber, the Soft Water Pads should be placed directly on the filter. It may be useful to increase the filter running time during the softening period.

How long does it take to soften the water?

This depends on the water hardness, the number of Soft Water Pads used and the flow rate. It can be from one or two days to two or three weeks.

Can I use the Soft Water Pads more than once?

This is possible. After use, the bags must be placed in distilled water with at least 30% salt content. This regenerates the Soft Water Pads.

How do Soft Water Pads work?

The Soft Water Pads contain a special mineral which is charged with sodium ions. These minerals release sodium ions in the water and absorb calcium ions. This makes the water softer.

I have a water softener in my house. Do I still need the Soft Water Pads?

Yes, a domestic water softener can only soften a certain amount of water at once. But never as much as fits in a whirlpool. Once the target water quantity has been reached, the exchanger granulate in the water softener would have to be regenerated. However, since much more water is allowed to run continuously through the water softener, unsoftened water also ends up in the whirlpool after the target water quantity has been reached.

How do I measure the hardness of my water after using the SoftWater Pad?

To measure your current water hardness we recommend the SpaBalancer Total Hardness Test Kit.

The SoftWater Pads should be well flowed through. Now I thought I would put the pads into the filter shaft and remove the filter. Can I do that?

Absolutely not. The pump could suck the SoftWater Pads and they could disappear in the pipes. So in any case leave the filters inside. You could attach the SoftWater Pads with a rubber directly to the filter. Or put them on the filters. Or tie them in the water in front of the filter shaft.

In the time I have the SoftWater Pads in the water, can I add UltraShock as well as the pH minus, as described in the instructions for refilling?

You can do the normal water maintenance while you have the pads in the water.

Can we take a bath while the pads are still in the water?

You can bathe while the pads are still in the water.

The SoftWater pads can be used several times according to the description, after placing them in distilled water with at least 30% salt content. Can the pads be stored for several months up to a whole year after they are no longer effective until they are regenerated in distilled water etc.? Does the regeneration still work after this long time?

I would not store them in the water. Bacteria can form. Leave the pads in the salt solution for about 4 weeks. Then add about 20 ml Ultrashock to the salt water. The Ultrashock prevents bacteria from forming in the wet SoftWater Pad. Leave the SoftWater Pads in the salt water for two more days. Remove the SoftWater Pads from the water. Let them dry a little. They must not become completely dry because the ion exchange resin beads will crack and lose their effectiveness as ion exchangers. Put the pads into the original bag and keep them there.

How long does it need to be soaked in salt water until it is regenerated?

You should leave it in the salt water for at least a week. However, it can also be left in it for longer.

Does the amount of water matter? Is 1 litre enough?

The SoftWater Pad should be completely covered by the salt water.

Does the water need to be mixed or stirred in between?

It does not need to be mixed or stirred.

Is distilled water from the tumble dryer with some lint suitable and can the SoftWater Pad then simply be washed off under running water?

"Dirty" distilled water can be used.

After use and regeneration, should it be left to air dry or stored wet in the bag provided?

After regeneration, the pad should be dried to the point where it is still slightly damp but no longer dripping. It must then be placed in the bag provided and sealed. The resin balls must not dry out, otherwise they will break and no longer be effective.
