What is EI?

EI stands for Estimative Index.

Quote from James' Planted Tank

Estimative Index was created By Tom Barr to be a simple method for dosing nutrients to planted tanks without the need for monitoring nutrient levels using test kits. Basically the aquarist doses the tank with a slight excess of nutrients throughout the week to prevent anything from running out and does a large water change at the end of the week to prevent anything from building up. In this way we can provide a close approximation or ‘Estimative Index’ of the nutrient levels during the week as we know what is being added and also what is removed in the water change. Estimative Index works best with high light systems and well planted tanks, but can be adapted for lower light systems by reducing the dosing.
