I have to ask, your not mixing your salt and water in the tank right?
Get some Power Heads at least two. I have one on the right side pointing down and toward the front, the other is pointing up and towards the back. I try to keep the flow going circular around my rocks. My Canister filter out flow is just doing it's thing and creating more movement.
I will also suggest you get a Skimmer!
Here are the powerheads I have.
Here is the Skimmer I have!
I would suggest this Skimmer because it's cheaper and it's the same brand. I didn't know they made this one otherwise I would have bought this one.
I don't have a sump tank with an overflow and using all the methods I have been using I have not had a cloudy top. I think a hang on the back Skimmer will really help you out! Also make sure to change your water every two weeks, and clean your canister filter out when you change your water. Just don't clean all the filter media out with clean water, use the dirty tank water that you suck out of the tank to clean your filters and sponges inside the canister. Good luck!
