My SPS/LPS tank uses a 250W Gisemann 12,5K MH and one 75W Coralife VHO blue, which I want to improve. Since just have space for 2x24in bulbs/reflectors, my options are change 75W Coralife for:

1) 2 x 75W URI 75 watt Actinic Blue - VHO
or
2) 2 x 24W T5 (Giesemann or Fauna Marin) with FM propper reflector

Which one is best option ?
