Recommended Filter For 20gal?

[SimonSays]

what would you guys recommend for a 20 gallon tank? preferably not too expensive, but works well with the tank! thanks!

Anything works really. As long as it filters then it works. You can buy the really cheap ones from the pet store as long as the flow is rated for 20g. The equation I use when measring flow is: 4 * Tank size = How much GPH you want. So if you have a 20g you gennerally want something that flows around 80 gph.

I've found it's best to overfilter, but if you do make sure the flow rate
is not to high for your tank.
An internal aimed at 30 gallons would be ideal.

Eheim aqua balls are good, they don't seem to take much room up in the tanks like fluvals.
plus there green and hide better with plants.
I have the 2210 with an extra basket.
