水草情迷

Just wondering is HQI must be better than FL ma? for my opinion HQI is good but the coverage is not as even distribute as FL la and coz of the temp. is too high so that why i hesitate to have one.....

umm.. for my opinion, use FL tube will be have more balance light output in the wide area of the tank, but FL can not reach tank size higher than 50cm, so most people will use HQI as light source because my tank height over 50cm and can the number of bulb is less than using FL tube. but HQI is very very hot is its side effect..over 100 degree wooo...
