pH- / KH- reducer

  • Phosphate-free preparation to safely reduce the pH level. Any pH influence should be tested with a pH test
  • With natural oak extract.
  • Before use the KH should be checked and adjusted to 4 - 8 GKH. (with JBL AquaDur plus).
  • To check the lime content of stones (add a few drops of pH-Minus to the stone: the development of foam indicates lime).
The best possible pH value for keeping most freshwater fish and plantes is the neutral range around 7. JBL pH-Minus lowers excessively high pH values in your aquarium and promotes fish health via added natural oak extract. Avoid any contact with eyes and mucous membranes. In the event of inadvertent contact, rinse with copious quantities of water. Keep out of reach of children.
