I have 2 of the c-530's. One is in service the other is in the garage. I called Marineland on the first one because of noise. They asked about the impeller and we exchanged a few more emails. They sent a complete new filter which I setup and installed back on the 180g. It's running and doing a fine job, it's just noisy. It's a little quieter than the first one but still very noisy. The 180g is in the living room. When I unplug the C-530 it gets fairly quiet in there except for the tanks with top filters. On those you just hear the water.
