cycling a new 550 gallon cube with a 15 gallon sump right now. I am currently looking for a new light for the tank. The dimensions are 24x24x20 and was wondering if the AI HYDRA 26 would be enough or if I would have to spend on the 52. I know bigger is better but do you guys think the 26 would be good enough? please let me know, and also any other suggestions on lights you guys might have used on similar tanks would be appreciated...
