種印度莕菜問題~

我之後係街度執左個魚缸返黎種印度莕菜...
但青苔問題極之嚴重....成日要換水

我想問用瓦缸/水桶種會唔會好d呢??我唔想每星期同佢換一次水
我見有花友用d正方形藍色桶種蓮花....好似幾好
想問可以係邊度搵到?(我個花槽唔係好大咋...放唔落d大瓦缸/水桶)

另外我想問應該用咩泥種?
佢e家種係一個同珍珠奶茶杯size差唔多既容器....d根生哂出黎
我想種過佢呀~

唔該哂大家

如果用唔透明嘅容器，水上面嘅水草生滿晒之後，就唔會有/得好少藻

yes, keep chaning water for short time is quite a problem, i want to grow the same thing too, but i am quite worry about the frequency of changing water also.
