Seachem Flourish (250ml)
Flourish® is a comprehensive plant supplement for the natural freshwater aquarium. It contains a rich assortment of important micro elements, trace elements and other nutrients. These include calcium, magnesium, iron and other important elements that have been shown to be beneficial to aquatic plants. For macro element (NPK) fertilization, use as needed.
Flourish® is designed to be used in conjunction with other macro and micro-nutrient supplements. Other manufacturers try to include ALL necessary nutrients, leading to overdoses of micro-nutrients in an attempt to raise macro-nutrient levels.

My aquarium plants have grown much healthier since I started using Flourish. The green color of the leaves is more vibrant and the plants seem more robust. I’ve noticed no negative effects on my shrimp either. It’s a simple and effective supplement.
John Walsh –
I used Flourish with my established tank and saw noticeable improvement in plant growth over a few weeks. The iron and magnesium levels seem to support better leaf development. I still use a separate NPK supplement for balanced nutrition.

After switching from another brand, my plants are thriving. The calcium and magnesium in Flourish support strong stems and healthy foliage. No issues with invertebrates. I recommend it for freshwater plant enthusiasts.
