Hi All,
I have a Sundial 36" T5 fixure with 39wx4 bulbs (Current). The photo period is about 5-6 hrs a day for 10 months. Do I need to replace the bulbs now or I can wait another 2-3 months before I put the new bulbs in.
Also, what bulbs that would promote coral growth? Someone suggested ATI blue plus & GE 6500k bulb (it is made in China, worry about its quality and bulb life).
I appreciate all comments and advices.
