Description

Seachem Flourish Excel Organic Carbon Planted Aquarium Supplement is a source of bioavailable organic carbon that helps aquatic plants flourish. While carbon is typically obtained from CO2 injection, this supplement offers a convenient alternative. It can be used on its own or in conjunction with CO2 injection, especially useful when CO2 alone results in dangerously low pH levels. It also has iron-reducing properties which promote the ferrous state of iron, making it more easily utilized by plants than ferric iron.

Key Benefits
  • 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).
  • also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).
  • Promotes easily utilized, ferrous-state iron as opposed to ferric iron.
  • Bioavailable organic carbon source for the planted aquarium.
Precautions

HAZARDS TO HUMANS: Do not eat, drink or get into eyes. In case of eye exposure, promptly & thoroughly wash eyes with water & seek medical attention.

FAQ

I have a AP Bio-Chem Zorb pouch in my filtration system. Will it scavenge the organic component of Flourish Excel?

Chemical filtration medias will have a very minimal impact on Flourish Excel but not enough to warrant removing them from your filter when you dose this product.

Is it better to add Flourish Excel at night or in the morning based upon plant carbon uptake physiology?

Carbon intake is a function of photosynthesis. Based on this, it would be ideal to dose Flourish Excel during the day. But given that Flourish Excel can stay complexed as a carbon source for up to 24 hours before it dissipates, you can dose at any time of the day and the product will be available for the next 24 hours. Flourish Excel is not carbon dioxide and there is no impact on pH using Flourish Excel.

Is Flourish Excel a replacement for CO2 in a planted aquarium?

Yes and no. It provides the same benefit as CO2, i.e. it provides the plants with a source of carbon for growth just as CO2 provides them with carbon. However CO2 by itself will give you quantitatively more growth than Excel by itself, although Excel does provide a substantial amount in comparison. If CO2 is a 10, Excel is a 6-7. Using both together provides additional benefit. One of the advantages of the Excel is no up front equipment costs and complexity of valves, hoses and regulators, etc.

I've been using Flourish Excel for the 4 days, and I've noticed that my Anacharis seems to be dying, while my other plants are doing fine. Why is this?

Anacharis is a particularly sensitive species (known to be sensitive to high temperature, trace copper, formaldehyde etc.). It is also sensitive to Flourish Excel. If you have Anacharis in an aquarium in which you are dosing Flourish Excel we recommend using Flourish Excel every other day rather than daily.

Is Excel safe to use with marimo moss balls? I’ve heard conflicting reports.

One side effect of using Flourish Excel that hobbyists have reported is that certain types of algae growth tend to lessen when Excel is dosed in an aquarium. Black beard algae seems to be particularly affected. Marimo moss balls aren't actually moss, but are actually a type of algae. Because of this, many people have been concerned about using Excel with marimo balls, however, the majority of the feedback we have gotten is that Excel has no negative effect on marimo balls when used according to directions. With marimo balls or any sensitive plant you can begin with a small dose and increase slowly over time after observing for any negative reaction. If the moss balls are the only plants or the tank is sparsely populated, reduce the dose accordingly as they are low-light, slow growing plants and will not use as much carbon as other faster growing plants.

Will the Excel kill Vals or will they adapt over time as some people suggested?

We had received reports from several hobbyists who said that they had seen Vallisneria melt when Flourish Excel was used with them. We also had reports of them thriving with Excel. Because of this, we decided to do several experiments to test this in our lab. We were able to make a few generalizations from our experiments and what we have heard from hobbyists:1. Large doses of Excel can sometimes cause some melting of the leaves of Vals. The larger the dose, the more likely there might be an issue.2. The damage is temporary; the roots aren't affected and it grows back strongly and tolerates future dosing of Excel even at higher than recommended doses.3. Vals normally tolerate the regular maintenance dose with no problem. In both experiments they weren’t affected by the daily dose, only higher doses.4. When other nutrients (nitrogen, phosphorus, iron, potassium) are dosed, Excel doses could be much higher without melting any leaves of the vals.

Is Flourish Excel™ safe for fish?

Yes, when used as directed, Flourish Excel is completely safe for fish.

    Plants love it!

    My plants were barely showing any growth before this- and I was using flourish as well. Just days after the first dose they were growing like crazy. Just be careful with dosing!

    Anubias No Algae

    By on

    I bought a little 4 oz bottle of this product to try from my local Aquarium store. I paid a higher price, though this product goes a long way since I only have plants in 2 @ one gallon, 1 @ 3 gallon, and 1 @ 5 gallon. Anubias grows slowly, not like Swords. I have used DIY co2 from a 2 Litre w yeast and sugar. I am preferring this product over the co2. This product has eliminated the algae growth on the plants, and in the tanks. The Anubias are growing fine, slow, but I have patience, and they are looking great.

    Great product for planted freshwater aquariums

    By on

    I read information on this product and being that I have 3 planted freshwater aquariums I wanted to get CO2 to help with the growth. I followed the directions on the bottle and slow but sure my aquariums are showing full, lush growth and this product DID NOT kill any of my fish. I recommend this product to anyone who cannot afford a CO2 system but wants CO2 in their aquarium and to get this from Chewy because of the price and their fantastic shipping and service.

    This stuff really helps keep live plants healthy.

    By on

    Can't say why it works but it really does. Been having problems with our water here lately so switched to all distilled. Plants started looking stressed and not doing well so started using excel at one capful per day (29 gal. tank) and after a few days the plants started coming back and all is now well.

    Kills staghorn algae!

    This killed the staghorn algae in my 20 gallon planted tank in just a few days at double dose. No harm to the rams or BN plecos!
