Description

MasterLine All In One Boost — Complete Liquid Fertilizer for CO₂ Planted Aquariums

MasterLine All In One Boost is a concentrated, all-in-one liquid fertilizer built for CO₂-injected planted aquariums that need maximum growth speed. In a single bottle it combines nitrogen, phosphorus, potassium, magnesium, iron and a full spectrum of trace elements (manganese, zinc, boron, copper, molybdenum) — the highest nutrient concentration in the entire MasterLine All In One range.

It's the fertilizer aquascapers reach for when running a heavily planted, fast-growing "Dutch-style" tank and want one bottle instead of juggling five different dosing bottles.

  • Comes with a graduated measuring cup for accurate dosing

Who is it for?

All In One Boost is designed for CO₂-injected tanks with high plant density and fast-growing stem plants such as Rotala, Ludwigia and Alternanthera. It's the strongest formula in the MasterLine All In One line — best suited to experienced aquascapers running Dutch-style or high-tech setups rather than low-tech or beginner tanks.

  • Store at room temperature, away from light, heat and frost
  • Keep out of reach of children and pets; do not ingest

Frequently asked questions

Do I need CO₂ to use MasterLine All In One Boost?
Yes. This is the high-growth formula in the MasterLine range, formulated specifically for CO₂-injected aquariums. For non-CO₂ or low-tech tanks, MasterLine All In One Lean or All In One Red is a better fit.

Can I use it with shrimp?
Yes, All In One Boost is safe for shrimp and other invertebrates when dosed correctly.

How long does one bottle last?
A 500 ml bottle provides roughly 500 daily doses for a 30 L aquarium (fewer, larger doses for bigger tanks). Also available in 200 ml, 1000 ml and 5000 ml.

What's the difference between Boost and Golden?
Boost is the fastest-growth formula in the range; Golden offers a more moderate growth rate focused on root health and thicker growth.
