Premium Iron Supplement for Planted Aquariums | Fast Foliar Absorption | Prevents Chlorosis
💚 Restore Vibrant Green Growth
Iron is immobile in plants, meaning it cannot be transferred from older leaves to new growth. When iron is deficient, symptoms appear first in young leaves, causing:
✔ Yellowing (chlorosis)
✔ Pale emerging leaves
✔ Short, slender stems
✔ Progressive lightening of new growth
Flourish Iron™ provides iron in the preferred ferrous (+2) form, allowing rapid uptake and correction of deficiencies in planted aquariums.
🔬 Why Iron Form Matters
When selecting an iron supplement, the oxidation state is critical:
❌ Ferric Iron (Fe³⁺)
Only soluble below pH 5.5
Precipitates in typical aquarium pH
Settles into substrate
Not available for foliar absorption
Often chelated as Iron-EDTA
Requires plant energy to reduce to ferrous form
✅ Ferrous Iron (Fe²⁺)
Soluble at all aquarium pH levels
Immediately bioavailable
Easily absorbed through leaves
No energy wasted on reduction
Flourish Iron™ uses a ferrous iron gluconate complex (not a chelate) for superior availability.
🌱 Advanced Formula Advantage
Highly Concentrated – 10,000 mg/L Ferrous Iron
Unlike iron-EDTA products:
✔ Weaker bonding than EDTA = better release
✔ Faster plant uptake
✔ No physiological energy drain
✔ More effective foliar feeding
✔ Provides additional carbon via gluconate
Despite common myths, ferrous gluconate is safe for fish and plants when used as directed.
🐠 Ideal For
High-light planted aquariums
CO₂ injected systems
Red plant enhancement
Rapid growth aquascapes
Correction of iron chlorosis
Professional aquascaping layouts
Perfect for gallery-style planted systems such as Nature Aquariums, Iwagumi layouts, Dutch style tanks, and contemporary aquascapes.
📌 Key Features
• 10,000 mg/L ferrous iron gluconate
• Immediate bioavailability
• Prevents yellowing in new growth
• Supports chlorophyll production
• Safe for freshwater planted tanks

Bioavailable organic carbon source for the planted aquarium
Use as an alternative to CO2 injection or in addition to it
Introduces photosynthetic intermediates
When you are looking at creating your first planted aquarium you have to initially decide whether you want to do High tec , or low tech , with regards to the infusion of CO2 gas into the water . If you went for the low tech solution wouldn't it be good to have a compromise between and all in CO2 system and a slow growth set up ? Well your prayers have now been answered in the product which is " Seachem Flourish Excel "
One of the first things young children are taught at school is that animals breath Oxygen and exhale CO2 , while plants take in CO2 during the day and release Oxygen . This is called photosynthesis , where plants used the energy in sunlight to convert Co2 and water to sugar and oxygen . The more Co2 in the air means the more plant growth there is
Flourish Excel is an additive for aquascaped aquariums that you can use as an alternative to CO2 injection . You simply add the Flourish Excel liquid each day to your aquarium and it becomes the carbon source for your plants . We don't claim that Flourish Excel would have the same growth rate as using CO2 but it is a great option available to you at a fraction of the cost , you just need to be a little more patient . For those of you already using a CO2 unit the addition of flourish excel into your aquarium could see a substantial benefit and is really useful for situations when continuing to add CO2 could result in very high pH levels.
Another benefit of Seachem Flourish Excel is that it has iron reducing properties which enhance the ferrous state of iron which is more easily utilized that ferric iron (Iron can exist in a number of different energy states but basically it occurs most frequently as Fe3+ (ferric)this is useless to plants as they can’t absorb it, plants need iron as Fe2+ (ferrous)
On initial use or after a major (> 40%) water change, use (5 mL) for every 40L

As Seachem Prime neutralises chlorine and chloramines, ammonia is formed as a side product, this happens with all dechlorinators. Prime has a unique benefit in that it neutralises the ammonia, but crucially, leaves it available for the tank bacteria to digest.
Also present in tap water are any number of highly toxic heavy metals, which Prime detoxifies and leaves them completely safe.Seachem Prime is non-acidic and will not change the pH
When used during water changes on established tanks, it's unique formula also helps in the reduction of nitrates, often a common problem on older tanks and increasingly a problem in some water areas, even for new systems.
If Seachem prime isused in a marine system, it will not cause the skimmer to either over produce foam or stop the skimming process, a critical factor to take into account for marine use.
The inclusion of essential ions within the formula will naturally encourage the fish to produce excess slime coating, it doesn't simply 'add a coating' to the fish, rather it boosts the fishes own natural defences.
Seachem Prime : dechlorinator, chloramine remover(via breaking the chloramine bond), ammonia detoxifier (but allowing the filter to consume the ammonia, so removing it), binds heavy metals, increases the fishes slime coat, helps with the removal of nitrate, safe for marine use.
The strongest, most complete,most concentrated, cost effective water conditioner currently available.
Directions Use 1 capful (5 mL) for each 200 L (50 US gallons) of new water. For smaller volumes, please note each cap thread is approximately 1 mL. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal
The Seachem Prime 500ml Dechlorinator is a water conditioner specifically designed to remove harmful substances such as ammonia, nitrite, and nitrate from the water in fish tanks. This product is suitable for all water types and effectively eliminates chlorine and other harmful chemicals to ensure the health and well-being of fish and other aquatic animals.
