Seachem Reef Kalkwasser 500g – Premium Calcium Hydroxide for Reef Aquariums

Seachem Reef Kalkwasser 500g is a high-purity calcium hydroxide powder specially formulated to help reef aquarists maintain optimal calcium and alkalinity levels essential for thriving coral and marine invertebrates. Known commonly as “limewater,” this supplement is critical for sustaining healthy skeletal growth in stony corals (SPS and LPS) and stabilizing water chemistry in marine reef tanks.

Why Use Seachem Reef Kalkwasser?

Maintaining calcium and alkalinity in reef aquariums can be challenging due to constant uptake by growing corals and organisms.
