仿真超市商品驚喜文具系列｜筷子墨水筆 藍色/紅色/黑色

The "Eco-Bio Ring Series" now features a new, uncolored black model. This brick breaks down water pollutants like fish feces and leftover bait, utilizing the power of BB bacteria. BB bacteria are naturally occurring microorganisms that thrive in water temperatures between 10°C and 65°C and can survive at pH levels between 3 and 11. It helps reduce the need for frequent tank water changes, and its effects last for about a year.
