When I got my first actual tank (my first fish were from some store that shipped out square boxes with 3 tetras in it...) was a litle 1.5 gallon. It had an air pump and no filter. When I got my 10 gallon, I had a filter but no air pump, same as now with my 30 gallon.
I am getting a bigger tank, 75 gallon, and was wondering.. should I ad an air pump to get extra oxygen into the water?
I was thinking about using real plants in my new aquarium.. but feel that I need to learn more about plants before I start with them. So If I am using an air pump.. would it be beneficial to my fish?
Thank you...
