## Description

desertcart.co.jp: APT ZERO Liquid Nutrient for Aquariums Except Nitrogen and Phosphorus 33.8 fl oz (1,000 ml) THE 2HR AQUARIST Liquid Fertilizer Aquarium Fertilizer : Pet Supplies

## Features

- APT ZERO, an all-in-one liquid nutrient that excludes nitrogen and phosphorus for aquariums with low plant content. It has excellent running costs, for example, if a 60cm aquarium is 10.1 fl oz (300 ml) for about 6 months, 16.9 fl oz (500 ml) for about 10 months, or 33.8 fl oz (1,000 ml). How do you need liquid nutrients if you use soil in your aquarium? 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
- ■Recommended environment
- Initial launch of aquariums using nutritional soil
- □ Rock style with low amount of water plants
- Aquariums with a large number of fish
- No CO2 added: If CO2 is not added, the speed of aquatic plants grow 5 to 8 times slower than when added, so nitrogen and phosphorus are often sufficient for biological exhaustion or soil supply. If you have a large number of fish or low weeds, this is the same
- Pump is not included as it is refillable. For example, a 23.6 inch (60 cm) aquarium will be equivalent to 33.8 fl oz (1,000 ml) 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 dose (7 times a week): 2ml/day ■Ingredients table Potassium [K] 3.8ppm. magnesium [Mg] 0.5 ppm, iron content: Fe] 0.05 ppm, trace elements; *Calcium is contained in tap water
