水草情迷

請問 30" 魚缸用2支150w, 5200k 的 hqi 要高過水面幾多 ?請指教 .

Thks.

Wow!!! That's so much of light! I had problem with 2 X 150W in my 36" and I had to block off about 30% of light to make it work, and still quite difficult to manage. I will say at least 2 - 3 feet away given your tank is relatively small.

chris0103兄.......你個缸幾高呀??? 通常水面離鹵素至少6吋左右.....

唉....那麼多的人玩 HQI.但是,他們玩過度哦。

最好10寸至12寸高

不對的,是6吋!
一個正常的尺寸,6吋是正規的

我個缸係16"高, 現在HQI 離水面是 8" , 正確嗎? Thks

如果出泡情況理想就可以了~

我有個建議,不如用兩枝70w hqi仲好啦!又唔怕有死位,又唔怕o的光勁過頭

Thks For All Information . ^.^

Its hard to tell whether 8" is right. For example, Dupla recommend at least 15" away from water surface while some people make it work less than that. Personally, I wouldn't have it too close to achieve the sun like effect, as long as the light has a good reflector which doesn't blind people getting close to the tank, its okay to have HQI quite far away without lossing much of the intensity.
