the only thing a filter will really be doing is mechanical filtration anyway. But like I said I am getting one. Plus the endlers and cherry shrimp don't have much of a bioload, I put one flake it and they do not finish it totally.
you dont even need a filter. I didn't use a filter on my 75 gallon. If the plants are growing, they are filtering the water. If you do 2 waterchanges a week you shuld be fine. IMO, no nano tanks should have filters. They are too big for such a small tank,and make it look ugly.
I made a homemade filter for my 5 gallon... I simply found an empty fish food container, punched a hole in the center of the lid, stuck a tube connector on a tube, put it in through the hole, opened the lid, and added gravel from a cycled tank. You could also add filter floss to this. I then connected the tubing to an air pump.
I careful hid my "filter" in 10 lbs. of gravel. You could get an air diffuser (sp?) to slow down the flow.
No tank should be without a filter, besides betta tanks (since they don't like a strong flow).
i have my nano 1 gallon running now for almost three weeks without any filtration or waterchange. it has a 9 watts over it. the plants are growing well. I beginning to see algae on the glass. I think I will have to clean it soon. I did ordered a nano filter from bigals just didn't have time to p ick it up from my friend yet
