The GreenWave tank media can be checked by using the following boil test
method. The GreenWave tank cannot be checked by using a hardness test be-
cause the elements that make up hardness will still be present in the water. A
hardness test will always show hardness because the GreenWave tank does not
remove hardness, it only isolates it and prevents it from scaling.
1. Fill a pan with about 1” of treated water.
2. Bring the water to a boil and allow it to boil violently until all the water has
evaporated.
3. Immediately remove the pan from the stove when the last bit of water is evap-
orated and allow it to cool.
4. The residual solids in the pan should wipe out easily with a wet cloth.
If the residual solids will not wipe out easily with a wet cloth, the media may need
to be replaced.
