2Hr Aquarist APT 1 Aquarium Fertiliser

2Hr Aquarist APT 1 Aquarium Fertiliser

2Hr Aquarist APT 1 is a premium liquid fertiliser developed for planted aquariums, delivering the essential nutrients aquatic plants need without adding nitrates or phosphates. Based on the same proven formula as the popular APT 3, APT 1 is specifically designed for newly established aquariums and mature planted tanks with higher fish populations, where fish waste already provides sufficient nitrogen and phosphorus.

Compared to conventional aquarium fertilisers developed for simpler planted tanks, APT 1 is 3× more concentrated for demanding plant species and contains 2× more potassium to encourage richer, more vibrant plant colours. Its highly concentrated formula makes daily dosing simple while supporting healthy growth and helping maintain balanced nutrient levels.

The standard 300ml bottle includes a calibrated pump that dispenses 1ml per press for quick and accurate dosing.
