So I recently purchased and cycled a 3.5 gallon aquaponic tank for a Betta. I’ve never had an aquaponic tank before and I wonder if they require more water changes than just weekly changes because the plants are the filtration? My nitrate levels have been increasing over the past week even with weekly changes. My tank has live plants in it and gravel as the substrate so it’s not an option to use a gravel pump because of the space and plants getting disturbed. Does anyone have any experience with a small Aquaponics tank?
