Then I realised that’s the pricision problem. The problem was solved after I turn all my amounts to accurate to two decimal places. For each Transaction: Derive Automatically.

底滤板 火山石打底 清洗 火山石冲洗2-3次。 用量 5 斤以内 铺设 平铺后，中间稍低，两边稍高；前低后高 青龙石随意摆放 铺放草泥 前面薄、后面厚 打湿水草泥种水草 种植水草 红绿3:4 前矮后高 两边绿中间红 阴性水草容易 对二氧化碳和光的要求不高。 加水，可以用海绵垫着，防止直冲 灯光 第一天24小时开 后三天每天 5-8 小时 换水 前三天每天换水 二氧化碳 第一个礼拜加大加倍 参考 https://youtu.be/ws89zmwJfcs?si=ig2uVxhgNnRwqy74 https://youtu.be/4weyFa3F9ws?si=aoo_XDUp0q0XPpev https://youtu.be/GxBvWuxhLrY?si=esdnaTrHllYSS5hb
