Plants need oxygen and co2, and while they'll do fine without any circulation (no filter walstad tanks exist), you'll notice your plants stay healthier and easier to care for with a filter. Staying with the idea of walstad, Diana Walstad actually recommends a filter for this reason; primarily for water circulation instead of removing nitrogen.
An aquarium water pump is a fish tank accessory that aerates and circulates water to make it healthier for marine life. The current produced by a water pump ensures that all water in a tank feeds through the tank’s filter. This constant flow evenly distributes nutrients throughout the tank, creating high-quality water that prevents diseases

Aquarium plants don’t need a filter to survive and thrive. I have several tanks without any type of filter installed and the plants are thriving. So unlike fish, plants don’t need an internal or external filter to survive and thrive. Believe it or not, some plants don’t even need additional light sources to do well. Don’t sweat about it, this shouldn’t be an issue. Best of all, you don’t need to empty your tank. A quick gravel vac should get rid of all the tiny particles resting at the bottom of the tank. If you find tiny bits floating through the tank, put some filter floss (50um) in the filter and this will get rid of the free-floating stuff. What Other Things Do Betta Fish Need To Thrive. Bettas need a filter and probably a heater, too, but it also requires the ideal temperature, slow-moving water, and an adequate amount of space to thrive. You can also decorate the tank with rocks, plants, and other objects to make it aesthetically pleasing and exciting for you and your fish. The filters need to be fully submerged to work correctly.

This is done by placing a small amount of water in the bottom of your filter and submerging it completely.

Filters for Frogs. Unless keeping species that inhabit rapidly flowing streams, use low-powered filters with aquatic frogs; the turbulence can be too much for them to handle, causing them to be thrown around the tank. Additionally, it's important to keep your frog from being sucked into the intake -- use a sponge or mesh barrier on the intake
