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 .
Visible reduction in filamentous algae and less dirty windows.
Progressive reduction of nitrates and phosphates, clear and stable water.
