ZOA Bacter is a concentrate of non-pathogenic live bacteria fixed on a maerl substrate, designed to stabilize the biological balance in both saltwater and freshwater aquariums. Its multi-strain consortium naturally competes with unwanted algae, lowers nitrates and phosphates through assimilation, and transforms organic deposits into resources for filtration. Result: cleaner windows, clear water and a healthier biotope. Fish and corals regain vitality and resistance (protection against vibrioses), while a beneficial biofilm is established to feed certain invertebrates. Compatible with skimmers and filters, the effect is quickly seen, especially with correct mixing. 40 ml bottle (34 g) – 10 9 CFU/g , GMO-free, no risk of overdose .

This kit includes everything you need to set up a “carbo-based” (sodium carbonate) Balling , up to 3x more concentrated than a classic Balling. It is particularly suitable for high-consumption reef aquariums and for those who wish to maintain a higher pH when the ambient air is rich in CO₂.
Populated reefs (SPS/LPS), systems with chronically low pH , or installations that require powerful and compact balling.
Mix Zoa Carbo in a quantity of reverse osmosis water according to the desired volume and concentration. The table below allows you to prepare 5 liters of solution in single , double or triple concentration. These doses are to be dissolved in reverse osmosis water. You can prepare smaller or larger quantities by dividing or multiplying the doses below.
| Supplements | Simple conc. for 5 L |
Double conc. for 5 L |
Triple conc. for 5 L |
| Zoa Calcium | 355 g | 710 g | 1065 g |
| Zoa Carbo | 265 g | 530 g | 795 g |
| Zoa Mineral | 120 g | 240 g | 360 g |
All our Balling products are prepared and packaged on site in our warehouse to guarantee freshness and traceability.
Objective: stable KH , higher pH and sustained coral growth , with a method that is simple to manage on a daily basis.
