水草情迷

Hi all,
In summer time, many of us use fan to cool down the water in our tank. The disadvantage of this method is that water level drops down real quick especially in small tanks. Here is a Japanese answer to this problem. I would think it only works with small tank since if you want to refill a big tank, the container will be huge!!!

Hope we all learn a thing or two and be creative, don't let the Japanese be the king of DIY innovation!

Very good idea !
