Seachem Plant Pack Fundamentals

The Seachem Plant Pack Fundamentals contains the three most important liquid supplements for planted freshwater aquariums in a single starter set: Flourish, Flourish Iron, and Flourish Excel — each in a 100 mL bottle. These three products cover the core nutritional needs of most planted tanks without requiring an elaborate multi-bottle fertilizer regimen. An ideal starting point for customers setting up their first planted aquarium or adding live plants to a shrimp or nano fish tank for the first time.

Flourish is a comprehensive trace element, vitamin, and amino acid supplement for stems and leaves. Flourish Iron provides concentrated ferrous iron (Fe+2) that plants prefer and readily absorb. Flourish Excel is an organic carbon source that supports plant photosynthesis without a CO2 injection system. Together the three cover plant nutrition from the ground up.

Why It Works

Product Highlights

01

Three Essential Supplements in One

Covers the core planted tank nutrition basics: comprehensive trace elements (Flourish), iron supplementation (Flourish Iron), and organic carbon source (Flourish Excel).

02

Beginner-Friendly Starter Set

Three 100 mL bottles provide enough product to trial the full Seachem fertilizer routine and determine what your plants need before committing to larger bottles.

03

Safe for Shrimp & Planted Tank Livestock

All three supplements are safe for freshwater shrimp, snails, and nano fish at the recommended dose when used as directed.

How to Use

How to Use

Flourish: 1 capful (5 mL) per 60 US gallons once or twice a week. Dose directly into the aquarium. For smaller tanks, each cap thread is approximately 1 mL. Flourish Iron: 1 capful (5 mL) per 50 US gallons as needed to maintain approximately 0.10 mg/L iron. Test iron within 30 minutes of dosing as it is rapidly absorbed by plants.

Flourish Excel: On initial introduction, use 1 capful (5 mL) per 10 US gallons. For ongoing maintenance, use 1 capful per 50 US gallons daily. Flourish Excel may be used as a partial substitute for CO2 injection or as a supplement alongside CO2. Do not overdose Flourish Excel, as high concentrations can stress certain sensitive plants like Vallisneria and some mosses.

Common Questions

Seachem Plant Pack Fundamentals FAQ

What does each bottle do?+
Flourish provides comprehensive trace elements, vitamins, and amino acids for plant stems and leaves. Flourish Iron supplies a concentrated, readily absorbed form of iron that prevents iron deficiency (yellowing between leaf veins). Flourish Excel is an organic carbon source for photosynthesis, useful when CO2 injection is not available.
Do I still need CO2 if I use Flourish Excel?+
Flourish Excel provides a readily available organic carbon source that partially compensates for the lack of CO2 injection. It can be used as a standalone carbon supplement in low-tech tanks or alongside CO2 injection in higher-tech setups.
How long will 100 mL last?+
This varies by tank size and dosing frequency. In a 10-gallon tank dosed once weekly, 100 mL of Flourish provides roughly 20 weeks of treatment. Larger tanks will use it more quickly.
What is the free shipping threshold?+
Free shipping on plants and dry goods at $75+.
Is this safe for shrimp tanks?+
Yes — all three supplements are safe for freshwater shrimp and invertebrates at the recommended dose. Note that Flourish Excel should not be significantly overdosed, as high concentrations can stress certain invertebrates and sensitive plants.
Do I need all three, or can I use them separately?+
Each bottle can be used independently and all three are available as separate full-size bottles. The Fundamentals pack is an ideal trial set to start with before deciding which supplements your specific planted tank needs most.
How is it shipped?+
Packed securely and shipped Monday through Thursday via standard ground shipping. Plants and dry goods ship free at $75+. Transit times vary by location.
Can I order this with livestock?+
Yes. Dry goods can ship together with livestock orders.
