Thank you for your comment ah flash8 … Since the water is only 16” deep. (3” soil + 1” gap at the top) So, I think T5HO will be bright enough and more economical ah… Hee, Also, I don’t want to use hqi (I know the light will be sufficient) because it will raise the temperature of the tank (More equipment to be added = More cost) and it is more expensive (about 1400 for two if DIY) than the T5HO …

That is the reason lo… Less cost is my objective ma, otherwise my wife is going to kill me ga la…
