The Aqueon was silent for a couple weeks, but then started making a deep hum. I replaced the Aqueon with a C3 today, and it's making a racket!
The loudest out of the box out of the 4 brands I've tried. I expected this after reading reviews/researching, and I'm sure it'll quiet down. If not I'll break out the Vaseline.
I think the inconsistent reviews are more due to people writing them shortly after getting the filter. I'm not sure why HOB
's are taking awhile to quiet down these days, I don't recall ever having this problem in the 90s. Maybe they just aren't made as precise as they once were. Precision = higher manufacturing cost.
I haven't run the C3 for long, so I don't have much to say about it other than loving the design. It got excellent reviews, and I'm sure they will hold true in the end.
Yep .... but just hang in there. My first C3 was horrible out of the box to the point I was going to get rid of it:
Two days of FluvalC3 are enough .. Best quiet filter?
But it's dead silent now. The C3 I got earlier this month came out of the box quiet and within a week was totally silent. About the same with my C4.
Also .... the inconsistency is absurd with the lids as well whcih is documented on numerous youtube videos. My first C3 makes noise with the lid on (and putting pressure on it does no good so the tape solution does not work) so I run it with the lid off. The second C3 and the C4 on my 29 gallon and the AquaClear 50 have no problem with the lids.
