Best Filter/Heater for a 20 Gallon Fish Tank?
I just really need some suggestions on brands…
I really don't know which filter would go best with a 20 gallon tank, suggestions would be great?
For the filter, can your suggestion be sure to "hold" the beneficial bacteria and when cleaning all you have to do is rinse it off in tank water so I don't have to do a cycle again?
All suggestions WILL be appreciated!
