ASF Reef Shot – Alkalinity (KH)

Stable Alkalinity for Strong Coral Growth

ASF Reef Shot Alkalinity is a ready-to-use, single-dose alkalinity supplement designed to quickly increase or maintain stable KH levels in reef aquariums.
Alkalinity is a core pillar of reef chemistry, directly influencing coral calcification, skeletal growth, and overall system stability.

Maintaining alkalinity between 7–9 dKH (2.5–3.2 meq/L) is ideal for most modern reef systems.
