FAUNA MARIN BACTERIA SYSTEM for nutrient reduction in Reef tanks  

UltraBio can also be used for nutrient reduction without the use of Zeolites or other adsorbers. If you want to use UltraBio without Zeolith, you have to use UltraBio in combination with Ultra-BAK as a food source for the bacteria.  

Dosing :  
Shake well before use  

1 drop each of UltraBio and 3 drops of Ultra-BAK per day per 100 L/26gal, directly into the aquarium.
Keep this dose until Nitrate and Phosphate levels have dropped significantly.
After you have reached the desired water parameters, decrease the dose by 50%.  


The combination of UltraBio and UltraLife are a very effective treatment against cyanobacteria in reef tanks. Cyanobacteria form red films or carpets which can cover the entire decoration. They are good indicators for a misbalance between nutrients. An addition of UltraBio and Ultralife will reactivate the growth of a healthy and diverse bacterial population by balancing out the nutrients.  


Different products have to be mixed before dosing.
The daily dose per 100 L of tank volume is 2 drops of UltraBio, half a tablespoon of UltraLife and 2 drops of UltraBio.
Mix all the ingredients together and add them into the intake of a pump or any other place with high flow.

Maintain this treatment until the Cyanobacteria are clearly reduced. This may take several days to weeks, so please be patient. In most cases the treatment works in less than one week.


UltraBio is a mix of highly active bacteria, specifically formulated for the Zeolight-System. This bacteria mix will prevents a monoculture in the filter, and promoteios the rapid processing of nutrients in the filter.

After this initial phase, add 1 drop per 100L/26 gal. every thre days, until the nest exchange of the Zeolith filter medium. Please add the UltraBio either directly into the tank or into the intake of the Zeolith Filtter.

It is advisable to turn off skimmer for 2-3 hrs after the addition of the UltaBio.

UltraBiop is a mix of several nitrifying and denitrifying bactreiapopulatioins that were carefully selected for their ability to convert amonia to nitrite. Nitrite to nitrate, and nitrate to nitrogen gas. Please add UltraBio a the beginning of the Zeolith system and after an exchage of Zeolite.

Our Bacteria Mix is highlyh concentrated. You can actually see the bacteria with the naked eye, as the aggregates drift in the solutioin. Please shake the bottle slightly before each use.

UltraBio contains the marine nitrifying and denitrifying bacteria strains, Nitrosomas sp. , Nirtobacter sp. ,Nitrospira sp., and Pseudomonas sp., and is highy concentrated.


In older tank with high nutrient concentrations, please reduce the phosphate concentration with Ultraphos, down to levels around 0.1mg/L - 0.05 mg/LBefore using UltraBak. After the phophate reduction, dose UltraBio as recomended above.
