Thrive S is a comprehensive supplement specially formulated for freshwater planted aquariums which contain shrimp. Due to the sensitivity of freshwater shrimp, it is important to have a balanced composition of nutrients. ThriveS does not contain copper which shrimp are especially sensitive to.
Copper is necessary for all living organisms, including shrimp. They are however quite sensitive to elevated levels and it is because of this that it is not included in Thrive S. Shrimp will get all the necessary copper from their diet. There is no need to add additional copper through the process of dosing for your plants.
Dose is 1 pump per 5g, 1-3x per week.
I am very pleased with the simplicity of this fertilizer and my plants response to it.
