I've had my HW-302 running for a week now and it's noisy, it rattles!!! I've read other users say that theirs is silent, that they had to double check to make sure it was running because they couldn't hear it, but mine is annoying me. Granted it is out in the open, not inside a furniture piece or something. It sounds as when you have something loose, not properly closed, but I would have water leaks if it wasn't properly sealed. I have unplugged it and plugged it back again and no change. I have shaken it vigorously to make sure there are no bubbles, tilted it back and forth, opened it and closed it, removed the baskets and placed them back again. No change. I am about to toss it!
This is my second canister filter, the first one is a Marineland C-160 that I thought it was too small for my tank (30g), got the SunSun, used the C-160 for a month, removed it, and replaced it with the HW-302, but the Marineland was a lot quieter. It is in the bedroom, so I am about to order a Marineland C-220 and get rid of this SunSun after only a week. It works fine, even though the Marineland is sturdier, thicker plastic. I am actually impressed that it works as well for the price and the cheaper feel of the canister.
I don't expect a filter to be "silent", they have to make some noise, but this is a little too much for me. Now, I don't have experience with canister filters and their noises, I don't have friends that have canisters for me to go check theirs, but I am going to AFA tomorrow to listen to theirs. All the times I've been there I've never paid attention to the filters under the cabinets but I have to compare noise levels.
It's driving me crazy!
