### ⭐⭐⭐⭐⭐ Review
*by R***. on 23 May 2020*

Un gran producto de la mejor marca de productos para acuariofilia. Un aporte necesario de CO2 para los acuarios plantados (si están muy plantados es preferible un sistema de inyección de CO2 por bombona) e, incluso, aditándolo por la noche, funciona como un gran antialgas. Muy recomendable!
