That is the question! I've got a 3.5 gallon tank kit and I'm currently using the filter that came with it. I just introduced our first live plant (java moss) to Bruiser's tank and he's blowing bubbles all over :-D So, I'm considering adding another low maintenance plant to his tank. My thoughts are that the combination of live plants and regular water changes will keep him happy and his water healthy so I could remove the filter. With the right amount of plants, do I need a filter in a 3.5 gallon tank? More importantly, other then providing a home to beneficial bacteria, what real purpose does the filter provide in a smaller tank?

thanks for your feedback

Bubbles!!!

From having experience on a non cycled tank compared cycled one, A cycled tank will have an effect on the ability of harmful substances such as ammonia, along with nitrites to buildup. Taking away your filter would make it much harder on you and your stress. due to the fact of the stressed caused by constant water changes which wouldnt happen as much with a bacteria colony.

the Plant will have a somewhat large effect in such a small tank depending on the size of the plant. Most of the time you wont see a substancial difference in the water quality unless the tank is moderately planted with plants such as hornwort, anacharis, and java moss that suck up ammonia and other toxic substances fast and efficient.
