## Description

desertcart.co.jp: APT COMPLETE Liquid Nutrient for Aquatic Aquariums, 16.9 fl oz (500 ml), THE 2HR AQUARIST Liquid Fertilizer, Aquarium Fertilizer : Pet Supplies

## Features

- Recommended for authentic aquariums such as large amounts of aquatic plants and small organisms. It has a balanced amount of nutrients needed for aquatic plants. It has excellent running cost, for example, a 23.6 inch (60 cm) aquarium will give you approximately 20 months of supply. Depending on your environment, you can manage your aquarium with this single tool. (We recommend using APT JAZZ, a solid nutrient for aquariums and roots that use a lot of fast-growing stemware and prefer to supply nitrogen from aquariums and roots when soil nutrients are depleted out.) How do you need liquid nutrients if you use soil? There are some aquarists who think of. But the nutrients contained in the soil are unstable. For example, you don't know how much nutrients are contained in the soil. Furthermore, the soluble nutrients are easily lost in water. If you want to bring out the health of your aquatic plants, we recommend using liquid nutrients from the start. APT COMPLETE is controlled with trace amounts of nitrogen so red water plants grow more dense and compact. It also helps reduce moss by keeping small amounts of nitrates in water
- ■Recommended environment
- Nature style with lots of aquatic plants
- □ In an environment where soil nutrients have been depleted over time from its launch
- Water tank without soil
- Aquariums with fewer organisms
- Pump is not included as it is refillable. For example, a 23.6 inch (60 cm) aquarium will give you approximately 10 months of supply for 16.9 fl oz Japanese instruction manual included
- ■How to Use Dosage Amount / Water Volume: 0.04 fl oz (1 ml/20 l) / Daily Dosage = [Water volume l/20 x 4] / 7 days ■Example: For 23.6 inches (60 L) of water tank □ Daily dosage (4 times week): 3ml/day ■Ingredients table Nitric acid [NO3] 1 .8ppm, Phosphate [PO4] 0.7 ppm, potassium [K] 4 ppm, magnesium [Mg] 0.4 ppm, iron [Fe] 0.03 ppm, trace element *Calcium is contained in tap water, so it does not contain calcium
