Seachem Laboratories Flourish Excel Plant Supplement 1.7 fl oz

If you love watching a planted aquarium fill in lush and green, Seachem Laboratories Flourish Excel Plant Supplement gives your underwater garden a steady source of organic carbon. This is the compact 1.7 fl oz bottle, a tidy size for smaller setups or for hobbyists who want to try carbon supplementation before committing to a larger volume. All plants need carbon to thrive, and Flourish Excel offers a bioavailable form to help yours do their best.

• Delivers a source of bioavailable organic carbon, which every plant in your tank requires to grow.
• Provides carbon that plants typically get from CO2, but here it is derived from simple organic compounds such as photosynthetic intermediates.
• Works as a flexible option, since Seachem notes it can be used either on its own or alongside CO2 injection.
• Gives you a substantial benefit either way, because producing and building on photosynthetic intermediates happen at the same time.
• Pairs especially well with CO2 in situations where adding more CO2 could push pH dangerously low, according to the brand.
• Also has iron-reducing properties that, Seachem says, promote the ferrous state plants can use.
• The 1.7 fl oz bottle suits nano tanks, desktop aquariums, and first-time carbon dosing.
• Helps round out a planted-tank routine when paired with the rest of your fertilizing schedule.
• Designed for the freshwater planted aquarium hobbyist who wants greener, fuller growth.
• An easy way to support root and leaf health without a full CO2 system.

Carbon is one of those quiet essentials. Your plants pull it constantly as they grow, and when the supply runs short, growth can stall no matter how much light you provide. Flourish Excel is Seachem's answer to that gap, a liquid carbon source you can fold into your normal dosing rhythm. The brand points out that the combination of Flourish Excel and CO2 is particularly ideal when more CO2 would tip your pH too low, so you have room to keep your water chemistry stable while still feeding your plants. Whether you run a single planted bowl or a modest aquascape, this small bottle is a practical starting point. Give your aquatic plants the carbon they need, and enjoy the payoff of a healthier, greener tank.
