Review: APTシリーズは色々出ていてどれがいいか分からず（エビが主に多いので）、とりあえず魚が多い物、でこちらを購入。 特にエビが☆になる事もなく大丈夫そうでした。 伸び悩んでいたウォーターウィステリアがこちらを試すようになったら水面までぐんぐん伸びるようになり、 モスも元気になった気がします。レッドミリオフィラムもかなり成長しまくったので切れたらまた買ってみようかなと思います。
Review: シュリンプがいるので気を使って説明よりも少量添加していますが、少量過ぎるのか水草は特に活性したとは感じませんが、栄養のバランスが良くなったみたいでコケがまるではえなくなりました。黒ひげやサンゴ状や緑コケなど見かけていましたが、コケ類が一切はえてきません。

## Features

- For aquariums with a low amount of aquatic grass and a large number of fish, APT ZERO, the all-in-one liquid nutrient excluding nitrogen and phosphorus is recommended. With excellent running costs, for example, a 23.6 inch (60 cm) aquarium, it can be used for approximately 6 months at 10.9 fl oz (300 ml), for 16.9 fl oz (500 ml), and 20 months for 39.4 fl oz (1,000 ml). Why do you need liquid nutrients if you use soil in aquatic aquarium? There are also aquariists who think of. But the nutrients in the soil are unstable. For example, you don't know how much nutrients are contained in the soil. In addition, soluble nutrients are easily lost by water change. If you want to bring out the health of your aquatic herbs, we recommend advertising liquid nutrients at the beginning of the launch. It can also be used with solid nutrients APT JAZZ to suppress moss. It is also recommended if you want to bring out the color of the aquatic grass that turns red due to nitrate restrictions. Also recommended for use when the aquarium is first launched (less than 3 months) or when using nutritional soil. However, over time, the nitrogen of the soil will dry out. We recommend switching to APT COMPLETE or replenishing nitrogen with APT JAZZ
- ■Recommended environment
- Beginning to launch an aquarium using nutritional soil
- Rock style with little weed amounts
- A fish tank with a large number of fish
- □CO2 is not added: If CO2 is not added, the water growth speed is 5 to 8 times slower than when added, so nitrogen and phosphorus are often sufficient for biological exhaust and soil. Even if you have a large number of fish or a small amount of aquatic grass is the same
- Pump is not included. For example, a 23.6 inch (60 cm) aquarium, 16.9 fl oz (500 ml) will last for approximately 10 months. Japanese instruction manual included
