Do I need a powerhead??

[erickrebsbach]

I have a 20L and would like some opinions. My tank is well establised almost 3 years now and over this three year period I have had my powerhead on and off. My question is this, Do I need it in a smaller 20L or can I get along with just my hang on filter???

You want your tank water to turn over 10-15X an hour. If your powerfilter does not provide that much flow you need to suplement. If it were me I would have a small powerhead regardless.

I would use something like a Maxijet 400 or 600 at least if it were me

3 or 4 minijet 606 i.e. 1 in each corner. Definitely use something - so you have good flow in the tank

Yes?

What do you have in your tank?

If you feel like you have dead spots definately add one or more. Besides, why not add a little cheap insurance? If your power filter dies, at least you have some water movement. Filters and pumps never die when you're home. Back-up can be the difference between a minor inconvienience and total loss of your system.
