The product had to undergo a long-term practical test in various aquariums and under various conditions. User safety is a very high priority at Dennerle. The old rule also applies to the active ingredient glutaraldehyde: the dose makes the poison. Glutaraldehyde in concentrated form is a hazardous substance. At a dosage of 3 ml per 100 L of aquarium water, the active ingredient is diluted by a factor of 33,000. This application concentration is sufficient to significantly promote plant growth, but is so low that the aquarium inhabitants cannot be negatively affected. In addition, glutaraldehyde is readily biodegradable in the application concentration used here. What the plants do not absorb is \"eaten\" by the filter bacteria - all that remains is CO \u003csub\u003e2\u003c\/sub\u003e , which in turn benefits the plants, and water. Even with long-term use, there is no accumulation of glutaraldehyde in the aquarium. A safety buffer is built into the dosage. Even accidentally dosing twice will not lead to negative effects.

In aquariums that have been undersupplied with phosphate for a long time, this means that the added phosphate initially \"disappears\" from the water again. After around 7 - 14 days of regular addition, when the plants have filled their phosphate stores again, the measurable phosphate content in the aquarium water then increases again. At this point, the amount of phosphate added should be reduced accordingly. Phosphate is a real growth engine, both for aquatic plants and for algae. Phosphate can therefore be used to control both plant growth and algae growth. It has proven useful to use phosphate as a shock fertilization with 0.1 - 0.2 mg\/L. You then only fertilize again when the phosphate content has been at zero for a few days. Aquatic plants can store phosphate better than algae. This method can be used to make life difficult for the unwanted algae. While the plants feed themselves from their internal phosphate stores and continue to grow in \"phosphate-poor times\", the algae \"starve\" and their growth is thus significantly slowed.

The nutrient ratios have been chosen so that all macronutrients are absorbed by the plants in equal proportions. Even with long-term, regular use, deficiencies or disadvantageous accumulations of individual nutrients cannot occur. Biological balance is particularly important with macronutrients, i.e. the nutrients should always be present in a certain ratio to one another. Nutrient imbalances should be avoided as they usually lead to algae problems.
