Lighting situation

So I got my 75 gallon tank. I have this awkward brace on top of my tank. I was wanting some opinions about what I should do. I was going to get a 4 or 6 bulb t5 fixture, but I'm thinking that it might cause a shadow. I was also thinking that maybe getting 2 radions or 2 kessils. Thoughts???

Depending on what lights you get will determine if you get a shadow or not but whatever you do don't remove the brace. With t5 you will get no shadow but if you go with 2 pendant style fixtures whether MH or led you likely will see the shadow but that depends on how high above the tank they are. The lower they are the less shadow but the more risk of burning unacclimated corals.

I don't think you'll get a shadow either way you go. I have a brace in the middle, with two led lights a foot above the tank on each side and there's no shadow. Also I've had t5's over the tank without a shadow also.

I am worried about my 280g though when I set it up. The middle brace is about 15 inches and the tank is 6 feet long. It is acrylic though so maybe the light will penetrate it well enough.

I have a buddy that has a 75g with LEDs and he has a shadow, could be due to them being DIY and he grouped each pendant pretty tightly. A premade led unit would probably have the led pods spread out more which would likely reduce if not eliminate the shadow.

I appreciate the help. I really really really want the radion lights, but don't know if budget will allow me to get two of them which i think i will need.

Ya you would need two, they are typically considered to cover a 2 foot square area each. I would save your money while the tank cycles and get two or post another thread about led lighting suggestions. Alot of members have been having success with an led unit that is alot more cost friendly, I believe the brand was taotronics but hopefully Carey or mr x can chime in and let you know, or you could private message them and ask.

I have read that the taotronics arnt any good as the leds are week (less than one watt each) and cant penetrate a deep tank well and that you should be getting leds of at least 2 watts 3 is better i am currently debating picking up a 150 watt led fixture by aquapro using 50 3 watt crees for my 24inch deep tank but i would need two of them on amazon they sell for around 200 im posting from my phone so putting a link to them is to hard for me at the moment but might wanna take a look they have a 75 watt one as well using 3 watters mix of white and blue with a switch for the blue and one for the white

Yeah they are using 3w LEDs driven at 2w each. Those suckers are powerful.
