I keep both soft and hard corals (sps) in my 30g tank and I am using 2x150W 20000K HQI + 1x39W T5HO Actinic 03 + 1x39W T5HO 11000K. The distance between the bulbs and the sand bed is just 21inches, do I need to upgrade the HQIs to 2x250W 20000K? And I want to replace all the T5HOs, but only D&D and some china made T5HOs are available in my country. As I know that, there are several T5HOs from D&D, such as actinic plus... etc. So which D&D T5HOs should I buy (I want to use 20000K HQI)?
Ah, also I want to know the URL of D&D, anyone knows?
Thx~
