I would replace it. In fact, with the same stuff just after I clean it a bit more.
The joy and beauty of a SW tank is never having to clean the sand. In freshwater tanks the cleaners are not very good, and eventually I always landed up cleaning it, taking everything apart. However in a SW tank the CUC critters do an awesome job. I have had my 90g for over 6 years with aragonite sand and I have yet to clean it, vacuum it or anything at all to it. Never remove it to clean it...that is only for freshwater fish tanks.
There are living critters deep in the sand like bristle worms that came on the live rock and set up house in the sand...you don't want to kill them (it is now live sand) and if you crab a handful of sand with one in it you will regret it...they sting.
You may need some more power heads (or adjust what you already have) to move the water over the sand enough to remove the built up sediment, but not disturb the sand and make piles.
The sandsifting starfish eats the fauna out of the sandbed and make it usless for it's true purpose of breaking down nitrates into gas to evaporate out of the tank. Nassaurius snails dig in and mix the sandbed, they eat any wasted food from it as well, they are a much better choice for cleaning the sand.
