ICP Element Alkalinity (Karbonathärte) - ALK - ATI

Maintain stable alkalinity with ATI ICP Elements Alkalinity, a concentrated supplement designed to accurately replenish carbonate hardness (KH) in reef aquariums. This single-parameter solution provides a precise way to correct alkalinity deficiencies and maintain the stable water chemistry required by growing corals. Alkalinity is one of the most important parameters in any reef aquarium. Stony corals, coralline algae, clams, and other calcifying organisms continuously consume carbonate and bicarbonate as they build their calcium carbonate structures. Without regular supplementation, alkalinity can quickly decline, potentially impacting coral growth and overall reef stability. ATI ICP Elements Alkalinity provides a reliable way to replace this daily consumption and maintain your desired KH level. Its concentrated liquid formula is easy to dose manually or with an automated dosing pump, making it suitable for everything from mixed reefs to high-demand SPS systems.   Key Features Concentrated alkalinity / carbonate hardness supplement Corrects low KH and replaces daily alkalinity consumption Supports healthy coral growth and skeletal development Helps maintain stable reef aquarium water chemistry Ideal for SPS, LPS, mixed reefs, and other calcifying organisms Ready-to-use liquid formula Compatible with manual or automated dosing systems Ideal for precise aquarium supplementation   Whether you're correcting low alkalinity or replacing the daily consumption of a coral-heavy reef, ATI ICP Elements Alkalinity provides a simple and precise solution for maintaining one of the most important parameters in your aquarium.
