I think I should agree with you. I replaced the azoo bulbs with my old bulbs
and the plants started to pearl again.

I just wasting my money . Maybe I should ask first before doing any
experiment.

wrong spectrum, try 6700 K, i have two and the plants are very beautiful.
blue light is to mimmic deep ocean water, like most corals like, plants
dont
grow very deep they are acustomed to another spectrum, 5000-6700K. too
much
blue light can increase algae growth.

take care.

I never tested my water perimeter but I consider I am not off track
when
I
saw my plants keep on pearling after several hours when the light on
daily.

Trying to improve the condition, I bought Azoo coral blue light to
replace
my existing bulbs, ordinary shoplight Philips TLD. My idea, if the
light
works well with coral then it should be worked even better with
plants.

To my frustration, my plants stopped from produce any bubble. I do not
feel
lack of co2 is the problem. My co2 injection is constant 2-3 bubble
per
second or in other word just like before I change the bulbs. I also
fertilised the plants like what I did previously.

Am I making a big and silly mistake by changing the bulb ? But the
blue
light give more pleasant looking.

Coral blue is the wrong spectrum for plants. Look for a bulb with
temperature between about 5300° and 6700°. It will appear much more
'yellow.'
