Hi Bappa,bmukh wrote: So if you have something like a cube, LED it is, but any longish tank, it should be T5HO. My cube 9rockscape) has one 50 watts LED and one 36 watts PLL..
Since i came late to your place and with so much to take in a little time i don't remember which tank as you have so many...
Which cube is this? What size is it?
I was just estimating why u need the PLL along with such a high powered LED?
Is it something because of the spread of light or something else..?
I plan on lighting an 18inch cube hence the query !
