More info

Most bacterial aquarium starter products have the problem, that bacteria won't develop very quickly or even dies off before being able to establish a working filtration colony, if there are not enough nutrients available. Dennerle Aquarium Start Rapid comes as a 2-component solution with a specifically developed nutrient, that will be added on a daily basis to help the bacteria grow.

2-component bio-activator

Aquarium Starter Rapid

  • For a rapid and safe aquarium start
  • First fish can be added after just 24 hours
  • For rapid biological activation of filter material and substrate
  • Adds the biologically "correct" bacteria to the aquarium right at the start
  • Active mixture of selected live filter bacteria + bacteria booster
  • Prevents fish losses
  • Strengthens the self-cleaning power
  • For all freshwater aquaria
  • Excellent bio-compatibility for all aquarium inhabitants (fish, shrimps, crayfish, snails, etc.)

Dennerle Aquarium Starter Rapid is a highly effective product for a rapid, safe start for newly established aquaria. It is made up of two components:

1. Living filter bacteria – they settle on filter material and gravel and instantly begin breaking down pollutants. The bacteria solution is highly concentrated, with a guaranteed 500 million bacteria per millilitre (when filled).
2. Bacteria booster nutrient solution - the specially developed "bacteria food" ensures rapid growth and reproduction.

How it works:

  • Powerful nitrification bacteria (Nitrosomonas, Nitrobacter) convert harmful ammonia into nitrate via nitrite, detoxifying the water
  • In the anaerobic areas of the aquarium - primarily in the substrate and the filter - denitrifying bacteria (Paracoccus) convert nitrate into gaseous nitrogen, reducing the nitrate content.
  • The filter bacteria also break down dead plant matter and food residues, fish excrement, organic impurities, proteins, fats, carbohydrates, harmful organic substances and organic sludge


Filter starter bacteria

Dosage: 100 ml in 50-100 L of aquarium water. Apply half of the starter bacteria to the filter material and put the other half into the aquarium water (25 °C).


Bacteria booster nutrient solution

Day 1: 50 ml in 100 L of aquarium water (25 ml / 50 L) - Day 2-6: 10 ml in 100 L of aquarium water (5 ml / 50 L) each day

Size: 2x 100ml, sufficient for up to 100L
