Long-term care for biologically healthy water - for up to six months.

Reduces the number of water changes required.

• thanks to the reliable stabilisation of the pH-value and the carbonate hardness value, chemical changes in the water quality are minimised, preventing sudden dangerous drops in acidity that can endanger the life of fish
• reduces phosphate and now also nitrate in a purely biological manner, preventing excessive algae growth (...)

Peat blocks are used as the lowest level in the aquarium.

• They slightly acidify the water and counteract the formation of algae.

Humic and tanning substances have numerous positive effects

• special advantage: The majority of the humic and tanning substances contained in TR7 Tropic have only a weak discolouring effect,
  or do not discolour the water at all. In contrast to many conventional peat products, the water does not take on an unsightly brown colour.
  Guaranteed free of phosphoric acid and hydrochloric acid.
• facilitates the acclimatisation and care of all fish from black water regions, such as discus, neons, scalares, dwarf cichlids and long-whiskered catfish

For the controlled adjustment of the pH-value and the carbonate hardness level.

• increases the carbonate hardness level and pH-value, e.g. in Cichlid tanks and for other species that require a pH-value between 7.5 and 8.5 and a water hardness of 10 - 15° dH
• allows the carbonate hardness level and pH-value to be precisely adjusted to planned or recommended levels
• compensates for carbonate hardness losses in marine aquariums and carbonate hardness losses that frequently occur in densely populated tanks (...)

High levels of phosphate cause an above-average growth of algae.

• 800 g of HOBBY Phosphate Killer binds 15,000 mg of phosphate without releasing it back into the water even when the material is saturated.

High nitrate levels help cause algae growth in aquariums.

• in addition, when there is insufficient CO2, the danger exists that nitrate can be reduced into nitrite, which is highly poisonous for the fish
• 250 ml HOBBY Nitrate Killer removes up to 12,500 mg of nitrate from the water in a short time by way of ion exchange and does not release it back into the aquarium water
