Seachem Plant Pack Fundamentals – Complete Starter Kit for Planted Tanks

Everything a New Planted Tank Needs in One Pack

Starting a planted aquarium means juggling carbon, iron, and trace nutrients, and it's hard to know which products you actually need first. Buy wrong and your plants stall before they ever fill in.

Seachem Plant Pack: Fundamentals bundles the three essentials for beginning aquatic gardeners – Flourish, Flourish Iron, and Flourish Excel – so you get broad-spectrum nutrients, maintenance iron, and an easy carbon source in one proven kit. Together they cover the core needs of a healthy planted tank without guesswork.

Every bottle in this pack comes from Seachem Laboratories, the science-driven aquatics company founded in 1979 in Madison, Georgia, where in-house chemists formulate each product. Plant Pack: Fundamentals is a curated entry point into the coordinated Flourish planted-tank system, pairing the comprehensive Flourish supplement with the carbon of Flourish Excel and the targeted iron of Flourish Iron so beginners start with the pieces that work together.

1. Dose Flourish for a broad spectrum of trace elements, vitamins, and amino acids.
2. Add Flourish Iron to maintain ideal iron levels in the plant-preferred ferrous form.
3. Use Flourish Excel as a simple source of organic carbon, alone or with CO2 injection.

Start your planted tank with the fundamentals covered. Add to cart.
