The Estimative Index (EI) Method, coined by Tom Barr, is a straightforward method for providing nutrients for a planted tank. The idea behind EI is to introduce an excess amount of nutrients within an aquarium, throughout the week. This excess of nutrients floods the water column and feeds the plants. This is an estimative method; measuring specific nutrient uptake rates is not necessary and no test kits are involved. EI provides a surplus of nutrients that helps to prevents plant deficiencies, and allows plant growth to out compete algae growth.
