KH Plus

The correct Carbonate Hardness (KH) is mandatory for clear pond water and healthy fish and plants as well as a stable pH. KH is a measurement for the total amount of dissolved carbonates in the pond water. When the KH is too low the pH can fluctuate which is very harmful for the aquatic life.

Sufficient for:

  • 1.000 ML= 7.000 ltr + 4˚DH
  • 2.500 ML= 17.500 ltr +4˚DH
  • 5.000 ML= 35.000 ltr +4˚DH
  • 15.000 ML= 105.000 ltr +4˚DH

GH Plus

A correct General Hardness (GH) is essential for clear water. GH is a measurement for the total amount of dissolved minerals in the pond water; these minerals mainly consist of Calcium. These minerals are essential for the well being of your fish and plants.

Sufficient for:

  • 1.000 ML = 7.000 ltr + 4˚DH
  • 2.500 ML = 17.500 ltr +4˚DH
  • 5.000 ML = 35.000 ltr +4˚DH
  • 15.000 ML = 105.000 ltr +4˚DH

Balantex

The KH and GH value can be maintained with Balantex. Regularly adding Balantex to the water prevents the KH and GH value from becoming too low. Too low KH value can lead to large fluctuations in the pH value, which is very harmful to everything that lives in the pond. Fish and plants cannot thrive in water with a low GH value.

Sufficient for:

  • 1.000 ML= 7.000 ltr + 4˚DH
  • 2.500 ML= 17.500 ltr +4˚DH
  • 5.000 ML= 35.000 ltr +4˚DH
  • 15.000 ML= 105.000 ltr +4˚DH

pH Min

The pH is mathematical reference for the amount of acids dissolved in pond water. The pH can have a value between 0 and 14. A low pH means the water is acid; high pH means the water is alkaline. Large fluctuations in the pH are harmful for fish. Especially when a filter has just started.

Sufficient for:

  • 1.000 ML = 5.000 ltr
  • 2.500 ML = 12.500 ltr
