A small dose is enough to make a real difference.

NYOS - Bacto Plus is a complete bacterial solution that works from the first drops. It contains a proprietary blend of seven highly active bacterial strains , capable of digesting excess nutrients such as nitrates, nitrites, ammonium, and ammonia. At the same time, it helps eliminate organic waste, sediment, and other decaying matter that pollute water on a daily basis. The result: crystal-clear water, a more pleasant odor, and long-lasting stability in the tank.
Its concentrated formula makes each milliliter particularly effective. Weekly use is enough to maintain optimal biological balance in both freshwater and saltwater aquariums. The product is also perfect for restarting a slightly unbalanced system or accompanying a major water change.
When setting up a new aquarium, Bacto Plus plays a vital role: it accelerates the cycling period by immediately establishing a robust and effective bacterial population. This is particularly useful when using artificial rocks or inert substrates that naturally lack microfauna. Within a few weeks, your tank will become more stable and can welcome its first inhabitants in optimal conditions.
The instructions are simple: for a new tank, dose 10 ml per 100 liters once a week for 2 to 4 weeks. Then, a maintenance dose of 2.5 ml per 100 liters per week is enough to maintain a good balance. For best results, remember to shake the bottle before use and turn off the UV during treatment .
