The Red Sea Reef Foundation B (KH) - 1 Litre is a ready-to-dose KH/Alkalinity supplement for reef aquariums, helping maintain carbonate availability, alkalinity stability and proper pH support.

1 Litre KH/Alkalinity Supplement for Reef Systems

This larger bottle is a practical option for aquariums with steady alkalinity uptake from stony corals, coralline algae and other calcifying organisms. Foundation B is one of the core components of balanced reef supplementation and should be managed alongside calcium and magnesium levels.
