How long will you turn on your fan daily?

on if temp high..

average, I on for 16hours

Turn on with the light which controlled by the timer. Therefore, 13 hours per day

I turn on the fan 24hrs, and keep the temp average at 28C for day.

I turn on 8 hours a day together with light. Temp drop from 31c --> 29c yesterday.

I opening 24 hour, and keep the temp is 27C to 28C.

Bird Nest兄: 恭喜,恭喜 you finally did it. The computer fan is worth to try, Right?

Termak hahaha thanks!

I think it is really safer than an AC high voltage fan!

Ai... i felt sorry regret as i threw 3 AC-->DC transformers away at the beginning of 2002 (i never use this for more than 10 years already). And now i need to pay again to buy a new one ar. so "Charm"~~~

我的魚缸是30吋,when I opening 24 hour, and keep the temp is 25C to 28C ,

How many fans you use ?

Are you using DC computer fan of HK$10 ?

I am using 18" tank, how many should i use ?

我用的是$10一把的電腦fan, 一共用了四把...... 效果真的很好,

Oh icic... so the water must vaporise very fast! But can reduce heat indeed.

一把12V小風扇24小時長開 晚上熄燈後停開，早上水温又升上31度。所以24小時長開。水温25至29度之間上落。
