+++ NEW JBL Fish food range ProNovo +++

The species-appropriate care of their animals is a matter close to every pet owner's heart. Even ornamental fish are increasingly being fed species-specific diets. The times when aquarium fish are fed exclusively with universal flakes for all ornamental fish are over. A species-specific diet for the fish species kept not only ensures well-being, colorfulness and good growth, it also protects against disease. Optimal utilization of nutrients means that the aquarium water is less polluted, thus preventing undesirable algae growth. The protein-fat ratio, which is very important for the organism, is often not optimal, especially with very cheap fish food, so that organ fatty deposits can occur in the animals. With ProNovo, JBL is launching a new food series on the market which is specially adapted to the nutritional requirements of the individual fish species. -uniquely species-appropriate-

+++NEW AQUAEL Flow Heater+++ AQUAEL Thermometer Link+++

AQUAEL Flow Heater is the first intelligent flow heater with variable power. Thanks to the novel SHS system, the power is automatically adjusted to the water volume. The flow heater is connected to the external filter. This eliminates the need for a heater in the aqaurium, creating many more design options than before.

AQUAEL Thermometer Link is an electronic WiFi thermometer. The temperature in the Aqaurium is permanently measured and stored. The data are transferred to the smartphone or tablet. Notifications can be set when the temperature is higher or lower.
