JBL Manado DARK 3l Ideal for freshwater aquarium plant care. Its porous structure stimulates root growth. Suitable for burrowing fish. High iron content nutrient reserve. Capable of absorbing excess nutrients and releasing them when needed. The high iron content can be absorbed by plant roots. Activates the soil flora by promoting efficient and...

JBL ProAquaTest CO2 Direct Refill Simple and safe monitoring of aquarium water parameters. Determination of the optimal carbon dioxide content in freshwater aquariumsUse: fill the plastic test tube with water to be tested, add the reagent drop by drop until stable pink coloring. Number of drops x 2 = CO2 content in mg/lUse in case of no or poorly...

JBL ProAquaTest K Potassium Refill For perfect plant growth: determine the optimal potassium level to control fertilization in freshwater aquariumsQuick test: fill a test tube with test water, add the reagents, pour the cloudy test water into the special test tube until the cross on the bottom is no longer visible, read off the amount filled. This...

JBL ProAquaTest NO3 Nitrate Determine the nitrite level for optimal plant growth or the origin of algae in fresh and salt water. Comparative laboratory system to compensate for clean water coloring: fill test tubes with water to be tested, add reagents to a test tube, place test tubes in the holder block, read the values on the color chart. Use:...

Magnesium Hardness Checker HC The hardness or hydrometric titer (TH) of water essentially corresponds to the presence of calcium and magnesium salts. It is directly linked to the geological nature of the terrain crossed. A calcareous soil will give hard water while a granite soil will produce rather soft water. The total hardness represents the sum of the calcium and...
