水草情迷

I am now using PML 11W PL 紅白管, the height of my 缸 is 14 寸 and the depth is 12 寸. Do you think its bright enough??

起碼要2支啦！

Is there any 40cm(16”) long light rack sell on Fish Street can support 20W or above PL tube??
Last time when I bought my tank with the PML light, the sales told me that 40cm long PL light rack only support up to 11W, is that true??

18寸缸的配件是較小型號可以選擇的。
20W好像只有24寸缸能用到。
你的Sales應該沒有說錯。

Is it mean the only method I can increase the bright of the light is to add another 40cm light rack with 11W PL tube
=> 2 light racks, 2 11W PL tubes => Total 22W

Or any Big Brother can get me some suggestion?? Thanks!

為一方法就是這樣！

我18"tank 用緊2支 24" 36wPLL, 因為頭尾火牛位無光，　所以用長小小，　草不會追光呀

Good idea, but the top of my tanks has not enough place to handle the 24" long tube ar...

Any other suggestion??

換缸囉！24寸的配置比較容易啊！

14"缸可用18W X 2 PL......我以前都係O甘用~

Owen, do you mean I need 2 rack for 2 18W tube
Or there is one rack which can connect 2 18W tube
How long is the rack you used before?

我買飛碟形 一個rack 兩支18w..... 個rack都十八吋o架~

18" is diddicult to buy lamp

2 PL is the good choice

我諗要最少70w先夠如果你想要睇到水草出泡

贊成beach boy 建議
和水流不要太急....否則無泡睇
