Aquavitro Eight Four

Introduction

Aquavitro eight.four is a premium, high-performance buffer formulated to raise and maintain pH and alkalinity (KH) in marine and reef aquariums. Unlike standard single-component buffers that struggle to hold pH above 8.0, eight.four uses a superior blend of carbonate and bicarbonate salts with an industry-leading pK of 8.6, making it easier to stabilize reef pH in the optimal 8.3–8.5 range.

This advanced, phosphate-free formula effectively counters acidification caused by organic acids while remaining highly soluble and safe for daily use. Aquavitro eight.four supports healthy coral growth and skeletal development and can be dosed daily alongside other aquavitro products without requiring multi-day intervals, allowing precise and active control of marine water chemistry.
