GROTECH CORALL A 
   Add to basketBasketAdd to favourites

One of the most important tasks of marine water aquaristic is to build an optimal surrounding, which is adapted to the demands of the invertebrates which have to be taken care of.
This comprises besides light, filtering and water quality also a refill of the trace-elements which have been absorbed by the invertebrates in an optimal quantity and composition.
Corall A, B and C are 3 trace-element mixtures which have to be dosed separately and which fulfill all requirements of the invertebrates in every respect.
The composition of Corall A,B and C has been optimized in cooperation with experienced marine water aquarists and during longterm tests in different aquariums, so that with the combined use of Corall A,B and C an equal excellent growing rate and colouring of soft, leather as well as hard corals will be achieved.

Corall A contains Strontium, Magnesium, Barium, Lithium ...

Corall B contains Magnesium, Iron, Chrome, Mangan, Nickel, Kobalt, Copper ...

Corall C contains Fluor, Iodine, Bor, Molybdenum ...

GROTECH KH 1 CARBONATE BUFFER 
   Add to basketBasketAdd to favourites

The solutions for the quick increase of carbonate hardness and Calcium contents.
In the marine water aquaristic the combined addition of kH+Ca 1 and 2 in a dosing of 15-20 ml/100 l aquarium water per week is recommended.
The liquids have to be dosed separately. Please do not mix in a measuring cup. In case of a combined use of kH+Ca 1 and 2 the ion proportion will not be moved within the marine water aquarium.

kH + Ca 1:The solution for a quick increase of the carbonate hardness.
The infeed of 50ml kH + Ca 1 increases the carbonate hardness by 2°kH with 100 l water. The ideal value is abt. 10° kH. The kH-value reflects the pH-buffer volume of the water. In case of a too low kH-value, there will be the danger of a pH-drop.
kH + Ca 2:The solution for a quick increase of the Calcium contents. 10ml kH+Ca 2 contains 200 mg immediately available Calcium. The ideal Ca-content of the ocean is between 400 - 450 mg/Liter. Please add kH+Ca 2 only in connection with the same quantity of kH+Ca 1 to the aquarium.

GROTECH MAGNESIUM PRO GRANULES 
   Add to basketBasketAdd to favourites

Additive for the Calcium reactor for the increase of the Magnesium contents. In the marine water aquarium, a great quantity of Calcium and Magnesium is required in order to achieve an optimum growth of corals and red calc algaes. With the normally used materials in the Calcium reactor, the Calcium content will be increased more than the Magnesium content. By mixing of up to 10% Magnesium pro into the used material, there will be a continuous feed of Magnesium and the Magnesium contents in the aquarium is stabilized.
