Need - Small Powerhead ... Edmonton

[JerseyJune]

Hi everyone !
I am looking to buy a small power head for my 20 g.
I have one that is 800 LPH ... No thank you a little too much !
If anyone has a small P/H to sell or knows a store where I can purchase.
I've dealt with larger tanks before (50, 60 & 90g), this is my 1st small one.
That would be greatly appreciated ! I've checked out most fish stores here in
Edmonton, no such luck, unless I have a larger tank.

Thanks again for the friendly advice
