Aquario Neo Fluid No CO₂ is a complete liquid fertilizer designed for planted aquariums without CO₂ injection. The formula contains nitrogen, phosphate, potassium, iron, and trace elements, so no additional fertilizers are needed. With regular use and good aquarium care habits, this fertilizer supports faster plant growth, stronger root systems, and the development of fresh new leaves! Great for tanks that contain stem plants or species that require good nutrition levels for proper growth.
Key Features & Benefits
- A true all-in-one macro and micro formula bundles nitrogen, phosphate, potassium, iron, and trace minerals, so you don't need secondary bottles.
- Tailored specifically for non-CO₂ layouts to encourage steady leaf development without overloading the water column.
- Promotes rapid root anchoring and faster growth for demanding stem plants and heavy-feeding column species.
Dosing & Administration Guidelines
- Standard Dosing Cap Scale: 1 full capful (on standard 300ml bottles) = 5ml
- Dosing Frequency: Add 2 capfuls (10ml) for every 10 gallons (40L) of tank water every 3 days.

Order arrived very quickly!
"Plants came very healthy and everything was delivered super quickly!"
So far so good
"Fast delivery of products. Excited to see how the Co2 tablets affect my scape."
Honestly Fantastic
"I may never buy another liquid fertilizer again. After using other liquid fertilizers that either just did not work or would turn the water green, I have never gotten growth in my plants like I have with this one. It's only been two weeks as of now, but I definitely already see a huge difference in my plant growth."
