Starter Bacteria - Bacteria for cycling a saltwater aquarium

The use of a bacterial supplement is particularly useful for quick starts and/or when using artificial rock. So-called starter bacteria accelerate the tank cycling by converting ammonia, which is toxic to fish, via nitrite to non-toxic nitrate. Nitrifying bacteria like Nitrobacter play a key role in the nitrogen cycle. In addition, the bacteria colonise free surfaces such as artificial rock, sand or panes right from the start and thus prevent undesirable microbial infestation.

Bacteria against Cyanos

Bacteria are a wonderful treatment against cyano layers in the aquarium. Ideally in connection with further actions (sucking off the coating, optimising nutrient levels etc.) "good" bacteria can quickly displace the cyano population and take their place. Phototrophic purple bacteria, which feed on light like cyanobacteria, are particularly strong competitors.

Bacteria as Probiotics

As prevention is better than cure, bacteria can be used to improve fish health. Particularly after transport or medical treatment, the natural microflora is weakened so that probiotics such as Saccharomyces or Bacillus subtilis strengthen the fish's defences.

Adding bacteria in seawater - tips for application

In the cycling phase bacteria can be used immediately. In order to ensure sufficient multiplication, we recommend the use in combination with a carbon nutrient dosing such as Tropic Marin Plus-NP. In this case, dose at the beginning of the lighting phase. In order to inoculate the filter material specifically, the bacterial solution can also be added directly into it.

In genereal, switch off skimmers, UV and ozone filters for 3-4 hours immediately before dosing. 

In case of a localized cyanobacterial mat on the substrate, you can use a syringe to inject the solution directly into the affected areas. In this case, you should avoid an additional carbon dosage, as this would also promote the growth of cyanobacteria.
