Potent CFL fixture for lagoons

[subsea]

The fixture with 200W 6500 kelvin bulb cost $110. Two of these over a 75G or 90G display would grow most anything.

In second picture, I am adding red macro attached to rock. Red macro appears to be Red Grapes. We shall see.

On this top lagoon tank, tale of two tanks thread, all of C. Paspodies feather Caulerpa has gone sexual. Not just the side with LED reef lights. It is still early to tell, but it looks as if some green emerging starts may be arising from the ghost white stakes of what was.k
