Flourish Phosphorus is a safe solution (4,500 mg/L phosphate) of potassium phosphate that takes the guess work out of phosphate dosing.

KEY FEATURES:
Phosphorus supplement for the planted aquarium
A safe 4500 mg/L solution of potassium phosphate
Takes the guesswork out of phosphate dosing
DIRECTIONS:
Beginner
Use 2.5mL (half a cap) for each 80L (20 US gallons) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, plant dark green).

Expert:
The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15-1.0 mg/L.

To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons, p=desired phosphate increase and m=volume of product to use in mL. For example to raise 20 gallons to 0.1 mg/L phosphate you would use: 0.8*20*0.1=1.6 mL.

Equilibrium is specifically designed to establish the ideal mineral content for the planted aquarium. Equilibrium contains no sodium or chloride. Equilibrium contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth.

KEY FEATURES:
Restores and maintains mineral balance and GH
Does not contain sodium or chloride like competing products
Ideally suited for use with RO or DI water or any mineral deficient water
DIRECTIONS:
To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16g (1 tablespoon) for every 80L (20 US gallons) when setting up an aquarium or when making water changes (add to new water). For optimum solubility we recommend mixing with 1L (1 qt.) of water (the resulting mixture will have a white opaque appearance). When this mixture is added to the aquarium it will impart a slight haze that should clear within 15-30 minutes.

Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a beneÞt from Flourish Iron because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it.

KEY FEATURES:
Highly concentrated (10,000 mg/L) iron source for the planted aquarium
Ferrous gluconate iron
Ferrous gluconate is better suited to foliar feeding than iron-EDTA
DIRECTIONS:
Use 1 capful (5mL) for each 200L (50 US gallons) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1mL.

Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium.

Key Features:

– Does not contain phosphate or nitrate making it ideal for use with Flourish Nitrogen and Flourish Phosphorus.

– Use Flourish Potassium to prevent potassium depletion and maintain the highest level of growth.
