AquaLabs Lean Grow 500ml

AquaLabs Lean Grow 500ml

Description: AquaLabs Lean Grow is a complete aquarium fertiliser designed for controlled growth and vibrant colours in CO2-injected aquariums. Through nitrate limitation, aquarists can enjoy deeper reds and less maintenance. This special formulation allows all essential macro and micronutrients to be delivered in one convenient bottle. It is safe to be used with fish, shrimp and snails.

Consider this formulation if you are setting up hardscape centric aquascape. The macronutrient ratios significantly limit the growth of green spot and green dust algae which are commonly seen on wood, rocks and slow growing plants. Additionally, the growth of plants will be slower and more colourful, allowing the aquarist to spend less time maintaining and more time admiring their work. If you are running a dutch style aquarium or just want faster growth, consider AquaLabs Max Grow.

Dosage: Shake well before use. Dose 1 pump (2.0ml) per 30 litres, 3 times a week. Perform a 30% water change weekly to retain nutrient levels within desired ranges.

Storage: Store in a cool, dark place away from sunlight.

Analysis: 1 pump (2.0ml) in 30 litres yields the following:

  • 2.67ppm Nitrate

  • 1.50ppm Phosphate

  • 4.30ppm Potassium

  • 0.01ppm Magnesium

  • 0.10ppm Iron

  • + Trace Elements

Highly recommend this for contest tanks

I used the Aqualabs lean grow fert on my 2023 competition tank that came first in the SAAC. I find that these ferts are very well balanced, giving the plants everything they need to grow fast and healthy, while also keeping the water column lean , so there is minimal chance for algae. I was able to reach my goal this year - grow lush and healthy plants with no algae. These ferts did just that for me. Would recommend to anyone that has a competiton tank!
