Sunken Garden Green: All-in-One Liquid Fertilizer for Planted Aquariums (100&200ml)

What is Sunken Garden Green?

It is a liquid aquarium plant fertilizer with macronutrients (nitrogen, phosphorus, potassium) and micronutrients and trace elements. It is dosed into the water column, where leaves and stems take it up. It suits low-tech and CO₂-injected planted tanks.

What do aquarium plants need to grow?

Light, carbon (CO₂ or a carbon source), and nutrients. A fertilizer supplies only the nutrients. If light or carbon is the limiting factor, adding fertilizer won’t speed growth.

How much fertilizer per litre?

Use 2 ml per 20 litres of aquarium water. That is 0.1 ml per litre. Dose 2 to 3 times a week.

How do I use it?

1. Shake the bottle well.
2. Calculate your tank’s actual water volume.
3. Add 2 ml per 20 L, 2 to 3 times a week.
4. Adjust gradually to your plant density and growth rate.
5. Do not overdose, and do regular water changes.

Frequently asked questions

How much fertilizer do I add per litre?

Add 2 ml per 20 litres of aquarium water, 2 to 3 times a week.

Will it cause or prevent algae?

Neither. Algae depends on light, CO₂, nutrients, and maintenance. A fertilizer supplies nutrients, but if light is strong and CO₂ is low, extra nutrients can feed algae. Dose conservatively, and keep lighting and water changes consistent.

Does it work in low-tech tanks without CO₂?

Yes. Use the lower end of the dose, since growth is slower without CO₂.

What do yellow or pale leaves mean?

It can mean a nutrient deficiency such as iron, nitrogen, or potassium, but can also come from low light, poor CO₂, or a new tank adjusting. Check the cause before increasing the dose.

Do I need root tabs as well?

For heavy root feeders in inert substrates, often yes. This is a water-column fertilizer. See Sunken Garden Root Tabs.

Can I use it with Sunken Garden Root Tabs?

Yes. Reduce the liquid dose if you see algae.
