I have one tank that is like your setup that has been up for 3 years. It is ok, but now I wish it was like my other tank that has been drilled, and then plumbed through an overflow to a sump underneath. This makes it possible to have suspended detritus overflow the main display, and go into the sump filtration to be easily removed. After some time, it can be a pain removing crud when it is not skimmed out that way. But the tank looked fine for the first couple of years in spite of this problem. Hair algae popped up in the third year, so have had to manually scrub corals, and rocks, along with using a phosphate removing product.
I recommend using chemipure elite, and the mechanical filtration provided with most hang on filters.
