ESV Kalkwasser Powder (Calcium Hydroxide)

Description

Calcium Hydroxide is a proven standard for maintaining calcium
concentration and alkalinity in closed marine aquaria. The calcium
provided is directly used by calcifying organisms, and the hydroxide
ions provided readily convert dissolved CO2 into bicarbonate and
carbonate ions, which are also directly used by calcifying organisms.
Our product is extremely pure and meets American Water Works Association
and Water Chemical Codex requirements.
