Dr Foster and Smith sells aquarium safe silicone lubricant:

I don't know if the regular stuff from the hardware/auto parts store works.

Thanks for the review. I might need to pick up a couple to replace some aging aquaclears I have.

Do you happen to know if the intake tubes are the same diameter? I have a couple aquaclear surface skimmers attached to my current HOBs and am wondering it the adapters will fit the fluvals.

Does this mean they're going to discontinue the older style Aquaclears?

That would be a shame. I've gotten used to their quirks and rather like them. Plus I figured out how to get highly efficient CO2 diffusion out of them.

Oh, one more thing. I recall someone reported success using teflon tape to silence a noisy impeller. You'd have to wind it the opposite direction from impeller spin to keep it from coming unwound; if it spins clockwise, wind counterclockwise.

I gave my last AquaClear away, so I'm not sure if the intake tubes are the same size. The new intake on the Fluval C-Series is black, it's length is adjustable and the grate is smaller in case you worry about small inhabitants or debris from getting sucked in. I use a sponge pre-filter on mine to protect the impeller. Overall it's a much nicer set-up IMO. I'm sure you could get the accessory to work with a home made adapter or some teflon tape.

You have some nice tanks, by the way.

I'll check out that lube.

I doubt they will ever get rid of the AquaClears. The Fluval version is more like a deluxe model.

Because impellers spin so fast, anything that sets them out of balance will make them rattle. I'm sure the teflon tape fix was an attempt to repair a damaged one. The problem with taping the magnet is the impeller is still inefficiently bouncing around, the noise is just subdued by the tape.

I have a C3 waiting to be installed. Question donnoj. Did you find that your C2 or C3 doesnt fit down on the rim of your tank all the way? I did a test fit the other day on mine and noticed that it doesn't go all the way down. It kind of sits on a tab under the output area and the intake tube is really tight against the glass. I wonder if it is supposed to sit up further than I was expecting or if the lip on my tank is wider than usual?

I checked my C2 and there's about an inch to play with. Check that the leveler at the bottom right side of the filter is adjusted correctly. Because the level adjuster is off to one side of the filter it's easy to have the filter sit crooked if your not careful.

My AC's had the same problem. I thin my fake wood trim on my tank is thicker than a normal black trim tank. I had to bump up to an AC110 to get one to fit without modification.

1 year update

Just thought I'd post an update on my Fluval C2 impeller lube, if anyones interested.

It's still dead silent, no rattle.

I also just purchased another tank and installed an AquaClear 20. It rattled out of the box. Applying some Vaseline to the impeller shaft fixed it. Silent with the lid on.

So just to reiterate what you did, you remove the motor, then took the impeller out of the well. Then lubed up the entire impeller (or just the part of it that sits in the well?) with Vaseline. Put everything back together. Relaxed there was no noise. Break out the beer?

Something along those lines?

Fish Shrimp tanks are like cups of coffee, one is never enough.

First, break out beer.

Second, remove motor from AquaClear/Fluval C.

Third, remove impeller.

Fourth, lube the shaft inside the motor. (Put a small glob on the end of the shaft, the impeller push it down the rest of the shaft when you install it.)

Fifth, install impeller on to lubed shaft and slide back down into the motor.

Sixth, install motor back onto the AquaClear/Fluval C.

Seventh, break out another beer and enjoy the silence.


ok, I've realized I used the word lube and shaft too many times for one day.

Haha! Hilarious! I guess I'll know what you're talking about when I get my AC20's soon. Guess the impeller has it's own tube, that doesn't show up in the parts manual haha.

I see now, I was like... my finger is too big to lube the shaft all the way down.
