I will assume you are setting up this tank, I have been reading posts here about this and the general concept is "don't worry about it" It will settle. If you are really just setting it up turn off pumps and filters it will settle. Water changes are the next thing mentioned mostly to hardly any to never and small ones. I think you don't need allot of changes until you add live stuff. With fishless cycling you could start filters and ammonia after the water has cleared. Once the cycle has been established some people use a large water change. I think getting plants established will help the water cloudiness issue. This will also require live things to provide food for the plants. This is my take as a algae grower, I hope others will chime in here to round out the subject.
