Dennerle Plant System S7, 250 ml

Plant System S7 is a highly concentrated multi-nutrient fertilser for aquatic plants in freshwater aquariums and is available in several sizes. S7 provides plants with essential trace elements and vital substances that promote balanced growth and produce lush green leaves and intense, bright colours. It also replaces nutrients that have been depleted and prevents deficiency symptoms.

Vitamins, plant enzymes and other organic substances are constantly being synthesised in nature with the help of natural sunlight. These vital substances not only promote good health and vibrant colours in fish but also in aquarium plants. Natural sources of vitamins, on the other hand, are in short supply in the aquarium. In addition, most vitamins do not remain stable for long or are quickly depleted. This makes it crucial to supplement these vital nutrients regularly.

Like all Dennerle fertilisers, S7 is also very well stabilised which ensures a slow-release effect.

Application and dosage recommendation:

Add 3 ml of Plant System S7 per 100 litres of aquarium water once a week. Add it in a place where there is good water movement so it can be distributed quickly and evenly.

The S7 concentrate fertiliser is the perfect way to supplement your fertilisation routine for plants, fish and beneficial filter bacteria.
