Superb products.
Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.

Muy necesario para cuidar bien peces y gambas en el acuario.
Muy bien producto a precio racionable, dar bien mediciones comprobado contra otras test kits mucho mas caro y todos muestra la misma nivel de GH y KH. Muy facil de usar aunque con agua muy blanda como el mio hay que mirar desde arriba contra algo blanco para ver el color de inicio en test GH.
