Tropical Aqua Plant Liquid Fertiliser

Tropical Aqua Plant is a liquid fertiliser containing nitrogen and phosphorus, formulated specifically for aquatic plants in aquariums with low fish populations. Where fish stocking is light, natural nutrient input is reduced — this supplement fills that gap, giving rooted and stem plants the building blocks they need to grow consistently and healthily.

What It Does

Low fish populations mean reduced organic waste, which in turn means less naturally occurring nitrogen and phosphorus in the water column. Tropical Aqua Plant addresses this directly, delivering both macronutrients in a ready-to-use liquid form that plants can absorb immediately.

How to Use It

Dose during water changes, at least once weekly, for consistent results. For best plant health, use alongside a ferric (iron) preparation — Tropical Aqua Plant covers nitrogen and phosphorus, but iron supplementation remains important for complete plant nutrition. The product works in both traditional planted aquariums and submerged culture setups, including those running CO2 injection. Dosage is 10 ml per 100 litres of water.

Suitable Setups

Effective in a wide range of planted aquarium styles — from lightly stocked community tanks to dedicated aquascape displays and CO2-supplemented systems. Available in a range of sizes to suit tanks of different volumes, from smaller aquariums through to larger planted displays.

Choosing the right bottle size for your tank volume and change schedule means you can maintain a consistent dosing routine without interruption — select your preferred size from the options above.
