水草情迷

What is different between "氣石", "氣木", "陶瓷氣石" ?

Many sales told me that "氣木" only for salt water !

想有細粒的氣泡!

Thanks !

"氣石" 最平既細化空氣, 耐用, 不過出泡大. 品質差既好快碎.
"氣石" 如果氣泵夠力, 可以出到好細泡, 不過好多時都係海水用多, 氣動底既化氮器常見, 好快就會發霉變黑, 就要更換新既.
"陶瓷氣石" 好多時都係白色成條狀, 出泡介乎於氣石同氣木之間, 亦係較貴既, 不過都幾易塞, 有些品牌可以將膠塞分開後, 用火加熱還完, 回復出泡量.
