Seachem Flourish Excel

Flourish Excel by Seachem is an excellent organic carbon supplement that’s used and loved by keen aquarium plant growers around the world. It can be used in planted aquariums as an alternative to CO2 injection or in addition to it.

The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Carbon typically comes from CO2, but it can also by derived from simple organic compounds which are found in this formula. Carbon is essential to healthy plant growth, and Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilised by plants than ferric iron (Fe+3).

Aquarists can achieve significant benefits when using Seachem Flourish Excel in addition to in-tank CO2 injections. The combination of these two carbon-based additives is especially suited for situations when continuing to add CO2 could result in dangerously low pH levels within the fish tank.

All plants require a source of carbon, and organic carbon directly benefits the growth and overall development of a wide variety of aquatic plants. Healthy plants create natural beauty in an aquarium, but they also promote a balanced ecosystem and provide many benefits to your fish.

Please be careful

Followed the instructions to the letter.
But absolute disaster. Next day, dead and dying YoYo and Hill Stream loaches.
All adults, healthy long living tank residents. Happend over two established big tanks.
Water parameters were as near to brilliant as you could get before using.
Don't know what happened, but Sorry won't be using again.
Great team, fast to respond and send, super over night courier, even between Islands.

Blackbeard Algae

Bought this to help suppress the blackbeard algae that was taking over the tank, seemed to kill off the last bits I couldn't scrub off, very happy with this.
