Seachem Flourish Excel
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

Seachem Flourish Iron
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 • Professional-grade concentration 🌿 Symptoms of Iron Deficiency If you notice: Yellow new leaves with green veins Increasing paleness in each new leaf Weak stem structure Your plants are likely iron deficient — supplement promptly for optimal results.
