Unboxing SUNSUN GRECH CBG-500 HOB filter (noisy?)

I bought this Sun Sun GRECH-500 with capacity of 10-30gallon because my old filter is not enough for my new aquarium 85cmX34cmX34cm. After 3weeks of using I cant say how good it is because I&using chemical to help my water clear but when I changed my filter after two week it really suck the dirt because my sponge was very dirty and has a very silent motor that you can&almost hear it. For me its a good filter because it already has skimmer and UV light.
