Aqua Clear impellers interchangeable?

[Tsuzot]

A local person has an Aqua Clear 70 for sale for $20 but it needs an impeller. Can I use an Aqua Clear 20 impeller in the 70 to lower the flow rate?
I'd like to put it on my 10g and I'm afraid the 70 with the stock impeller would be to strong. I was thinking with the 20 impeller the flow would be lower but I'd still have the big media basket for extra filtration.

I don't think they fit as the 20 is much smaller . I have like 30 + aquaclears .Great filters .
The replacement impeller for the 70 is only $15 so $35 for a 70 is not all bad . New is $50 usually.

The impellers of aquaclear 20-70 are all interchangeable.

^^ I am corrected and agree ^^
My bad !
I just ordered al sorts of parts and note only one impeller on my shelf..They do all fit 20-70 and like OP asked have different amount of paddles so a 20 would just run a 70 slower..Tubes change at 70 and pumps change on 110 I believe..They are a very universal filter as far as parts go.

I'll be putting it on a 10g that already has a 20 on it. I was hoping to pull the impeller out of my 20 and swap it.
Do you know anything about aftermarket filter inserts. He said he had an acrylic insert that changes the way it flows through the filter for it he'd sell for $15 extra. He said he used it as a refugium on a salt water tank.

Correct size impellers are cheap enough online. For the proper performance, I'd recommend getting the proper impeller.

This is probably what he is talking about:
InTank AquaClear 70 Media Basket

It forces the water to go through the sponge and down, then up through your media.
