Thrive+ is designed for tanks with a ph of around 7 or below. Thrive can be used at any ph level. Thrive+ contains 60% more iron and two forms of nitrogen(organic and inorganic). If you have a higher tech tank with a ph of around 7 or below then go with Thrive+, if not go with Thrive.
All of the Thrive products supply a comprehensive assortment of nutrients with one exception. If you have a soft water tank you are also going to want to add a gh booster(Magnesium and Calcium). Other than that you are good to go.
This comes down to a question of the focus of the tank. If shrimp are the focus of the tank then you want to go with ThriveS. If the focus of the tank are plants then go with Thrive, Thrive+ or ThriveC. If you have ever had a shrimp focused tank before then you know the importance of water stability. Water changes are important, but they are normally small and infrequent.
ThriveS is designed to not increase the necessity of water changes above what would normally be done with good tank maintenance on a shrimp tank. While Thrive, Thrive+ and ThriveC are shrimp safe they are concentrated to provide the plants with all the necessary nutrients, which also increases the need for frequent larger water changes.
ThriveC is designed for lower tech tanks or tanks with a high bio load where nitrates can reach elevated levels. ThriveC has lower levels of nitrate compared to the other nutrients. When dosing ThriveC you are still getting all the other nutrients without adding as much nitrate as you would with Thrive and Thrive+.
You certainly could just dose less Thrive or Thrive+ to help with elevated nitrate levels, however when doing this you are also reducing the levels of all the other nutrients. Nutrients such as iron and potassium as well as a few other micronutrients are not commonly supplied by fish waste so dosing a well rounded fertilizer is important in these tanks. ThriveC does just that, it has lower levels of nitrogen as well as phosphorous (which can also creep high in heavyily stocking tanks), while still providing adequate levels of potassium, iron and other important micronutrients.
