Measure & control
Something in the aquarium doesn't seem to be quite right. Algae, aquarium plants or corals die or aquarium fish die for no apparent reason. Recognizable? Then it's time to measure your water values. With an aquarium water test you can measure the most important water values in your aquarium and establish whether your aquarium is in good balance. This is important because the water values tell you whether and which actions you must perform to get a beautiful aquarium or to keep it.
