Call me crazy but if each LED unit equals a 250w Halide would you really need 3-6 fixtures on a 90?.. I can't imagine anyone having 6 - 250w halides on a 90 gallon tank.
- 55 gallon aquarium – 3 fixtures
- 58 or 65 gallon aquarium – 2 fixtures
- 75 or 90 gallon aquarium – 3 or 6 fixtures, depending on how much coral you plan
- 125 or 135 gallon aquarium – 8 fixtures, depending on how much coral you plan
- 180 gallon aquarium – 8 fixtures for full coverage
