APT All-In-One Estimative Index EI Fertilizer 2hrAquarist Dennis Wong Advanced Planted Tank Aquarium Plant

Product Description:

Award-winning aquascapers’ choice.

Designed to exceed the maximum estimate of plant-growth requirements, the famous nutrient dosing approach pioneered by Tom Barr is now available in a ready-to-use concentrate that removes the guesswork from trying to recreate this powerful and sometimes elusive formula.

The default dosage saturates the water heavily with NPK, Mg, Fe, and Traces, removing nutrient deficiencies from the equation and allows the aquarist to then focus on tuning light, CO2, and other variables. An overview of the EI methodology can be found here.
