125 Gallon Reef Tank 8 months old- still cloudy

[bobby7]

Hey all! I have a 125 gallon reef tank. I have had it up for a while now. I have tried every single thing I can imagine as well as researched other reasons. I tried chemicals, filter changes, 80% water change at least twice along the way. I have done all but break it down and start over. I even removed every spec of salad and replaced with gravel because I thought my powerhead was kicking up all the same. I keep checking my parameters and they all fall inline with your standard reef tank (yes even the ph, calcium, and alkalinity.. I know someone will ask that lol) Is there ANYTHING that anyone can suggest? I’ll post a photo for viewing pleasure, though you can’t really seem much.

I should add that I upgraded my tank 8pm that ago from a 75 to the 125 but I have not added anything new since then because I’ve been so diligent about the cloudiness.
I’m running a Fluval FX4.
