Does anyone know how to make water crystal clear? I can't make my water to look clear. I have a hang on back filter and also have a sump. I'm not sure if my sump is doing its job. Any suggestion?

Agreed Need more info.
Maybe try putting the HOB hanging on the sump. You shouldn't need an HOB filter if you have a good skimmer etc.
bio protein skimmer?
What the heck are you doing with 2 tangs and an angel in a 30 gallon? I assume you plan to move them, but still this is adding to your problem...
Not the best filtration + that many large fish = lots of junk floating around.
