Aquario Neo Plants Tab FE is a targeted iron root fertilizer that addresses iron deficiencies in aquatic plants, such as chlorosis, where new leaves emerge pale, yellow, or bleached white. Manufactured using advanced slow-release technology, these substrate tabs allow heavy root-feeders to absorb essential iron without leaching excess elements into the water column.
| Tab Type | Key Composition | Target Deficiency Symptoms | Primary Effect & Ideal Usage |
|---|---|---|---|
| Tab 1 | Nitrogen, Phosphoric Acid, Potassium | Phosphate or Potassium Deficiency: Red leaves turning green, old leaves melting away, or holes forming in old leaves. | Comprehensive fertilizer promoting quick growth; ideal when a general nutrient shortage occurs or when growing red plants. |
| Tab K | Potassium | Potassium Deficiency: Distinct pinholes forming in older foliage or yellowing leaf borders. | Promotes photosynthesis; ideal for restoring osmotic balance and plant tissue strength. |
| Tab Fe | Iron | Iron Deficiency: New leaves lack color, turn white, or red aquatic plants lose rich coloration. | Enhances color development; resolves new leaf chlorosis and boosts red plant vibrancy. |
| Tab St. Long | Organic Fertilizer Blend | Calcium Deficiency: Abnormal, twisted, or stunted new growth tissue. | Long-lasting slow-release organic formula; ideal for heavy root feeders, established soils (>1 year), or rescaping. |
| Solid / No CO2 Tab | Substrate Carbon & Organic Nutrients | Carbon Shortage: Sluggish growth rates in low-tech aquariums without gas injection. | Provides substrate-based carbon support; ideal for low-tech setups without pressurized CO2. |

1. How do I know if my plants need Aquario Neo Plants Tab FE instead of liquid iron?
Heavy root-feeding stem plants and species with established root systems absorb iron very efficiently directly through the substrate. If new growth appears chlorotic (pale or white) or if red plants fade to dull green, placing Tab FE directly near root structures delivers concentrated iron without fueling water column algae.
2. Can Aquario Neo Plants Tab FE trigger algae growth?
Because the nutrients are engineered for slow-release burial within the substrate, nutrients remain localized around the plant roots rather than leaching into the open water column, drastically reducing the risk of fueling surface or glass algae.
3. How does Tab Fe fit into the rest of the Aquario Neo Plants Tab lineup?
Aquario Neo Plants Tab Fe supplies targeted iron to resolve pale leaves and boost vibrant red colors. In contrast, Tab 1 serves as a broad macro nutrient source, Tab K supplies targeted potassium to fix leaf pinholes, Tab St. Long provides long-lasting organic nourishment for depleted aquasoil, and Solid / No CO2 Tab supplies essential carbon support directly to the root zone in low-tech aquariums.

"Best way to get Iron to my plants. I’m getting better reds than dosing the water column."
"I can't speak to if they grow plants well as I've just put then in my tank for the first time. But they stayed planted in my substrate and did float out. That I'll give 5 stars to"
"Really makes my red pop!"
