## Description

Seachem Flourish Freshwater Plant Supplement - Aquarium Element and Nutrient Blend 2L / 67.6 oz

Review: Works great - Nice supplement for plants.
Review: Been using this for e decade - Easiest way to keep a planted tank healthy when properly maintained, last years and MUCH cheaper in this quantity. We only have a few tanks but all are planted. Use a substrate like CaribSea Eco-Complete for a maximum effect since it will absorb this once its initial supply is used. I was having failure after failure in the planted coffee table tank but it now uses that substrate and this freshwater plant supplement. It now looks like a jungle. I have a different approach in my other tanks but all use a LITTLE of their Prime for water changes and then this.

## Features

- SUPPLEMENT: Seachem Flourish is a comprehensive plant supplement for the natural freshwater aquarium, containing a rich assortment of important micro elements, trace elements, and other nutrients.
- ELEMENTS: In order to benefit your aquatic plants and help your freshwater environment thrive, Seachem Flourish contains potassium, calcium, magnesium, iron, and other important elements.
- WATER TREATMENT: For best results, use 1 capful (5 mL) of Flourish for each 250 L (60 US gallons) once or twice a week. For smaller doses, please note that each cap thread is approximately 1 mL. Refrigeration is recommended 3 months after opening.
- SOLUTION COLOR: It is normal for the color of Seachem’s Flourish to vary by batch as the solution color is dependent on the temperature at which the product was blended. This variation in color is of no consequence to the function of Flourish.
- SAFETY: Seachem Flourish is safe to use for invertebrates such as shrimp, but is designed to be used in conjunction with other macro and micro-nutrient supplements in aquariums only.

Nice supplement for plants.

### ⭐⭐⭐⭐⭐ If you have plants in your tanks, you need this
*by G***R on January 8, 2013*

This is the ideal plant fertilizer for tropical aquariums, at least in the US. It is the only liquid fertilizer that I have seen that is comprehensive, which means it has all the nutrients needed for plant growth and in the right proportions. Most fertilizers I have seen only contain a couple, for example Iron and Potassium (Potash). Flourish has in it: Total Nitrogen 0.07% Available Phosphate ( P2O5) 0.01% Soluble Potash 0.37% Calcium (Ca) 0.14% Magnesium (Mg) 0.11% Sulfur (S) 0.2773% Boron (B) 0.009% Chlorine (Cl) 1.15% Cobalt (Co) 0.0004% Copper (Cu) 0.0001% Iron (Fe) 0.32% Manganese (Mn) 0.0118% Molybdenum (Mo) 0.0009% Sodium (Na) 0.13% Zinc (Zn) 0.0007% The dose for this is pretty minimal, so if all you have is a single tank of small to moderate size you should just get the 250 mL or 500 mL bottle. As an example, a 20g tank only needs a dose of 1.6 mL per week so a 250 mL bottle would last you 156 weeks which is a little short of 3 years! The good news is, this product does not expire so having it around for that long is not an issue. If you have a large tank, you can get Flourish in a larger bottle. I have a 125g, 20g, 10g, and 5g aquarium to dose weekly so I use the 2 L bottle. Plus, if you look at price, a 2 L bottle is far cheaper than buying four 500 mL bottles. So buy in bulk if you need it, it won't go bad! I do keep mine in the refrigerator though. The label says you don't need to, but I figure there must be some reason they recommend it. Tip: Add your Flourish 24 hours after your weekly water change. The reason being most water conditioners will bind to 'heavy metals' of which flourish does contain some (for example copper). Plants need this, so you want to keep it available to them. Don't worry about your fish, the levels are extremely low. Second Tip: If you have moderate to bright lighting, you may wish to try doing two doses a week. Light and nutrients must remain in balance, or you'll have algae issues.
