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.

Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO₂, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). Therefore, one can derive a substantial benefit with the use of Flourish Excel™ either alone or in conjunction with CO₂ injection.

Flourish Iron™ is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement. It should be used in those cases where the iron requirements exceed that which can be delivered by Flourish™ at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins.)

My tank is doing terrific. I am using [Flourish Nitrogen™] at about 4-5 capfuls per week an am not seeing any algae problems at all because the plants are growing just great. I have to trim my cabomba at least once a week and my anubias barteri has bloomed twice and it's never done that before. Also, my dwarf sag. grrass is sending out so many runners it's like regular grass.

I was searching the internet for a inexpensive method of adding carbon dioxide to my aquarium, and I found your web-site and a description of Flourish Excel™. It was exactly what I needed! I asked my local aquarium store to order some of it for me. I was amazed at the results I saw within three weeks. I then ordered Flourish, Flourish Iron™, and Flourish Potassium™.... My plants showed a dramatic improvement. The java fern no longer turned black and spotty. The Amazon sword plants in my other tank doubled their number of leaves. But the most amazing thing was that plants I was unable to even keep alive before such as cabomba and red ludwigia are now "Flourishing!"

I just wanted to tell you how great your Acid Buffer is. I have been trying to lower the pH of my water for about 2 months now but it kept going back up. Out of the tap my water is has a pH of 7.6-7.8 and is very hard. Your product was the only one that would lower the pH of my water and maintain a constant level.
