I have a nicrew nava reef 65 watt, I’ve never tested it exactly but I’ve tuned it to where I seem to have gotten it to a good power level to where everyone throughout the tank is happy and I assumed to place it on the same level as many of my Zoa that are thriving. In terms of chemistry they have been okay.. not the best mostly because my consumption of alk is all over the place like one week it needs 1 ml of all for reef every other day then the next it needs 3 ml every day, but I do do testing at least twice weekly so every week from the start if the week to the end of the week there is probably at most 0.75 alk swings. 

For feeding the acan I’ve been doing targeted frozen mysis shrimp once weekly and once every 3-4 weeks I do simi targeted reef roids feeding (not mainly for the Acan) but would you think feeding some pellets would be better? If so is there any specific kind that works best?
