125 reef breeders suggestion

I have a125 that I plan to have softies, lps and anemone would I be ok with just two of the photon 24 I'm trying to save as much as possible. It has a center brace

 

For LPS and softies, yes. Our Photon24s will cover 36" of tank no problem

 

I don't really know anything about LEDs but how high should they be and at what % do they need running also can they be put in a canopy

 

You will be at 6-8" off the water with 90 degree optics. Start at 25% power and work your way up 5% every few days. They can be put in a canopy, but you must drill holes in the top for the fans, and have fans removing warm, moist air from the canopy. If you keep the air cool, the LEDs will stay cool, shoot for less than 90 degrees (fixture temp, not air temp), the cooler the better.

 

Do I need to buy more fans and if so what kind and how many

 

1 computer fan on each end of the canopy, pulling air out

 

Ok I have one more question sorry. What is the difference with 90 and 120 optics and which is better for my tank

 

The 90s are a little tighter, so you will need to mount the light higher. I prefer 90s, as they reduce light spill, and will still work over 36" of tank.

 

Can the value fixtures be put on a timer

 

Yes, They can, and the blues and whites/colors can be switched on and off separately.
