In total of wattage is 476watt with all my lights(96watt PC and 382watt fixture.
Remember my tank is 32"h
If anybody knows a better fixture then this. Please post.

 

Does it have to be a fixture? What are the dimensions of the tank?

 

Well no, but I'm not the diy type of guy.

36"w x 32"h x 15.5"d

 

I think he was asking because there's also pendants.
