水草情迷

各位用光管的朋友,大家覺得哪一支光管是最好的?

請寫下牌子型號,及大約價錢

Please state wattage and length for the tubes you want to know about.

How about 18W PL for 18" tank

Well, a basic question, good for which area?
- good for our eyes?
- good for our pocket ($$)
- good for tall slim growth?
- good for red color.......
......etc.
depends on what do you want to achieve.

for my case, also using 18" tank, I found I am satisfy with normal daylight FL tube (18") from any hardware store. Each cost me HKD6-8 dollars. I use four of them. At least I get bubbles from plants, of course get some algae too!!!

my exp.

18W PL X2 (AQUA-ONE)
11W PL X1 (P.M.L)

請問 18W PL管是否有三波段燈管?? 如果有的話, 大約多少錢和是什么牌子型號?

係咪靜管先??

是的

about $70 per one.

最好既光管咪係飛利浦865系列囉！又夠平，又係三波長，又唔會時間耐左光度弱左好多，只會永遠保持咁光！咁既光管真係好過買ADA！

雪山飛狐兄, 請問飛利浦865系列是否有PL管, or 只有FL管??
