I have a biocube 29 with evergrow LEDs on it currently and I want to replace them with an aqua illumination fixture. My question is, will 1 be enough? And I'm trying to decide between the Hydras, Hydra 52s, and the Vega. I'm leaning towards the Vega becuase of how controllable they are. My tank is a mixed reef, with everything from SPS to leathers. The SPS are all up really high on a rock however I am not getting much growth from them.
