2HR Aquarist APT Complete – Premium All-in-One Aquarium Plant Fertiliser
If you’re looking for a premium aquarium plant fertiliser, 2HR Aquarist APT Complete is one of the best all-in-one options available for planted aquariums.
APT Complete provides a comprehensive blend of macro, micro and trace nutrients in one easy-to-dose fertiliser. It’s especially well suited to planted tanks where plant demand is high and fish stocking is comparatively lower.
For anyone wanting healthier growth, stronger plants and better colour without juggling several different fertilisers, APT Complete keeps things simple.
What Is 2HR Aquarist APT Complete?
2HR Aquarist APT Complete is an all-in-one liquid aquarium fertiliser developed specifically for planted tanks.
Its formula includes important nutrients such as:
- Nitrogen
- Phosphorus
- Potassium
- Magnesium
- Iron
- Additional micronutrients and trace elements
Rather than simply pushing maximum nutrient levels, 2HR Aquarist focuses on providing nutrients in a controlled ratio designed around healthy, manageable plant growth.
Who Should Use APT Complete?
APT Complete is particularly suited to heavily planted aquariums and aquascapes where the plants require more nutrients than the fish and substrate alone can provide.
It’s a great option for:
- High-tech planted aquariums
- CO₂ injected tanks
- Heavily planted aquascapes
- Tanks growing demanding or colourful plants
- Aquariums with relatively low fish stocking
It can also be used in lower-tech aquariums, although these tanks will often need a reduced dose depending on plant mass, lighting and growth rate.
APT Complete Dosage
The standard 2HR Aquarist APT Complete dosage is:
3 mL per 100 litres daily.
That works out roughly as:
60L aquarium: 1.8 mL daily
100L aquarium: 3 mL daily
200L aquarium: 6 mL daily
300L aquarium: 9 mL daily
Consistency is more important than the exact time of day you dose.
Does Aquarium Fertiliser Cause Algae?
This is one of the biggest concerns people have when they start fertilising planted aquariums.
Adding fertiliser does not automatically mean more algae.
Healthy aquarium plants need adequate nutrients, light and carbon to grow properly. When plants become deficient and lose vigour, they can actually become more vulnerable to algae problems.
The goal is balance rather than simply adding as much fertiliser as possible.
APT Complete FAQ
Can I use APT Complete without CO₂?
Yes. Lower-tech tanks generally require less fertiliser, so the dosage may need to be reduced depending on plant growth and stocking.
How often should I dose APT Complete?
The standard recommendation is 3 mL per 100 litres every day.
What is the difference between APT Complete and APT Zero?
APT Complete contains a broader range of macro and micronutrients, including nitrogen and phosphorus.
APT Zero is designed more for tanks where fish waste and other sources already provide enough nitrogen and phosphorus.
Is APT Complete good for red aquarium plants?
Yes. Red and other demanding aquarium plants often benefit from a stable supply of nutrients, especially when combined with good lighting and CO₂.
Is 2HR Aquarist APT Complete Worth It?
If you want a high-quality all-in-one fertiliser for a planted aquarium, absolutely.
Instead of trying to dose several individual products, APT Complete gives your aquarium plants a comprehensive nutrient supply from a single bottle.
For heavily planted tanks, aquascapes and anyone looking to take their planted aquarium to the next level, 2HR Aquarist APT Complete is one of our top fertiliser recommendations.
