Flexi Reef is a reef aquarium supplementation brand built around an adaptive method that tailors dosing to an aquarium’s current condition. Rather than relying on one fixed formula, the system guides reef keepers through a short assessment of tank type, maturity, biology issues and nutrient levels, then generates a custom recipe for two blends, A and B. Users prepare the blends, dose them, and can update their recipe as the aquarium and its needs change.

The product range supports different stages and goals, from maturing tanks to established aquariums with growing coral demand, as well as tanks experiencing dinoflagellate or cyanobacteria issues. Recipe ingredients may include macro and trace elements, amino acids, peptides, vitamins and nutrients. Flexi Reef offers Mini and Max starter packs: Mini covers core elements and trace elements, while Max adds the broader supplement groups for the full method. The brand also provides dosing guidelines, preparation and mixing instructions, a blend recipe calculator, aquarium-stage guidance, educational reefing articles and information for prospective business partners and influencers.
