【アクアリウム】CO2添加をやめた水草水槽の今。寿命を迎えたソイルで維持しています

This August marks the 3rd anniversary of my 90cm driftwood aquarium, and I'd like to share its current state. Actually, six months ago, I stopped adding CO2, which is considered essential. The soil's nutrients have completely depleted and it's turned into mud, but the aquatic plants are thriving, even needing trimming. This time, while doing maintenance, I'll discuss: Why aquatic plants grow beautifully even without CO2 How to maintain a tank with soil that has reached the end of its lifespan and how to deal with blue-green algae The characteristics of aquatic plants that dislike ammonia (such as water lawn) My adorable hand-tamed velvet blue shrimp, which I've been breeding for over 5 years, will also make an appearance! My goal is to maintain it for 5 years. Please watch until the end. 🍀 Main aquatic plants featured: Water lawn, Cryptocoryne, Marsilea, Sagittaria, Pearl grass, Rotala blood red, Aponogeton, Nymphaea, Anubias, Microsorum, Bucephalandra, Vallisneria
