2Hr Aquarist APT Complete (APT3) – All-in-One Planted Aquarium Fertilizer
2Hr Aquarist APT Complete, now known as 2Hr Aquarist APT3, is a comprehensive all-in-one liquid fertilizer developed for planted aquariums. It provides a balanced combination of essential macro, micro and trace nutrients in a single formula, making regular aquarium plant fertilization simple and consistent.
APT3 is particularly suited to established aquariums with higher plant mass and comparatively lower fish load. Its nutrient formulation is designed to support demanding aquatic plants while promoting healthy growth, stronger plant form and rich coloration.
Complete Nutrition in One Bottle
The 2Hr Aquarist APT Complete fertilizer supplies essential nutrients required by aquarium plants without requiring separate bottles for individual macro and micronutrients.
The current APT3 guaranteed analysis includes:
- Total Nitrogen (N): 0.75%
- Available Phosphoric Acid (P₂O₅): 0.69%
- Soluble Potash (K₂O): 4.52%
- Magnesium (Mg): 1.10%
- Iron (Fe): 0.12%
- Essential trace nutrients
APT3 uses multiple nutrient sources and chelated forms of iron to provide plant nutrition across varying planted aquarium conditions.
Designed for Rich Plant Colouration
APT3 uses a carefully balanced, nitrate-limiting nutrient approach. Rather than simply maximizing every nutrient concentration, the formulation balances nitrogen availability with the requirements of healthy plant metabolism.
This approach is particularly useful for aquascapers growing colourful stem plants and red aquatic plants such as Rotala and Ludwigia species.
Suitable for Demanding Planted Aquariums
2Hr Aquarist APT3 Complete is an excellent choice for established planted tanks containing a substantial amount of plant mass.
It can be used for:
- High-tech planted aquariums
- Aquascaped tanks
- CO₂-injected planted tanks
- Red and colourful stem plants
- Carpeting plants
- Established community planted aquariums
- Tanks containing demanding aquatic plant species
Good fertilization works together with appropriate lighting, CO₂ where required, water circulation, biological filtration and regular aquarium maintenance.
APT Complete / APT3 Dosage
Standard Dosage: 3ml per 100 litres daily.
APT3 can be dosed at any convenient time of day. Consistent dosing is more important than dosing at a particular hour.
For aquariums without CO₂ injection or tanks consisting mainly of slow-growing/shade plants, nutrient demand may be lower and dosage can be adjusted accordingly.
When changing from a substantially different fertilizer regime, introducing APT3 progressively can help the aquarium adjust to the new nutrient regime.
Which 2Hr Aquarist APT Fertilizer Should You Choose?
APT3 / APT Complete is designed primarily for established aquariums with more plants and fewer fish, providing comprehensive macro, micro and trace nutrition.
For newer aquariums or tanks with higher fish load and lower plant mass, APT1 / APT Zero may be more appropriate.
For heavily planted aquariums where the aquarist specifically follows the Estimative Index methodology, APTe / APT Estimative Index provides a different nutrient approach.
For newer tanks or aquariums with more fish and fewer plants, consider 2Hr Aquarist APT Zero.
For heavily planted aquariums following the EI nutrient approach, consider 2Hr Aquarist APT Estimative Index.

Good results
Significant growth and coloration of the plants the best fertilizer period.
Magic elixir if you have mostly red plants…my red plants showing neon red colour in just 3 days use… little high in macro and micros hence start with half the recommended dose and increase to full dose to stop algae bloom
Awesome product . Plants growing really well and colourful.
Better price listed here than the amazon
Really nove fertilizer. Imparts good plant colouration and keeps algae at bay to am extend.
My high tech 120l tank is always pearling. The reds are really popping out. A must if you have red plant and the colours aren’t showing.
Very good product
One of the best.
Very good for red plants
