Brown algae everywhere !

I agree with most, I am not a fan of a canister filter on a reef tank. they work great on fresh water tanks, even on a fish only salt tank. On reefs I like either a wet/dry or refug. refugium being better in my opion. I also feel a skimmer is very important. There are some good skimmers out there that you don't have to spend a lot on for a 55 gal. Bak pak is good, also prism, stay away from seaclone.
If you want spend more I like the turboflotter 1000, very easy to use and setup.
You do not have to use cycle, continue to use stress coat to declorinate. I would not leave the light off if you have live rock. Start putting in coral, you should be fine. first i would do another water change, and check your levels.
